You rely on your brakes each day. Despite this fact, most people rarely think about their brakes until there’s a problem. Unfortunately, a problem with your brakes can have major consequences. Car brake replacement is a serious subject.

Signs that Car Brakes Need Replacement

Knowing when your brakes need to be replaced is a great way to avoid problems. The only thing is, you might not know or recognize the early signs. If your brakes become too warn, they might do enough damage to make it a costly repair and maybe even require professional servicing.

Watch for these classic signs indicating your brakes need to be replaced:

• Squealing: If your brakes make a high-pitch squeal each time you press on the pedal, that’s usually a sign the pads are too far worn. The sound is made by a metal shim or indicator that’s designed to get your attention. Sometimes, though, if your car has been sitting where it’s exposed to water, the brake discs develop a thin layer of rust. This generates a squealing sound, but it is temporary and won’t keep up for long.
• Grinding: When you hear a grinding sound as you step on the brake pedal, not a squeal, that almost definitely means your brake pads are worn to nothing. As the caliper, which holds the pads, scrapes against the discs, the metallic grinding is produced. If you don’t address this problem right away, irreparable damage to the rotors is imminent.
• Vibration or Fluttering: As you push on the brake pedal, you might feel a vibration or slight flutter. During hard braking situations, like if a car pulls in front of you, this could be the ABS system pumping the brakes for you. This is different, because you feel it all the time, even when casually slowing to stop. Over time it grows. Usually, this is an indication the discs are warped, usually from riding the brakes as you go down steep hills repeatedly. Sometimes the rotors can be resurfaced and saved, otherwise they must be replaced.
• Pulling: As you brake, you might notice the car consistently pulls left of right. This is a sign the pads have worn unevenly, or that something foreign got into the brake fluid. Obviously, not only can this be annoying, it’s dangerous.
• Diminished Power: If you notice your brakes don’t stop as well as before, or that the brake pedal just sinks to the floor of your car, that one of the signs of old car brakes. This problem usually means you have a bigger problem than worn brake pads. Likely, it’s a sign that the brake lines are leaking, or at least that you need to top off the brake fluid reservoir. If you also notice an oil-like substance pooled wherever you park the car, a leak is likely.

If you notice one or more of these issues when you step on the brakes, car brake replacement may be necessary. At the very least, you may want to consider a visit to your mechanic to make sure there isn’t another underlying problem.

DIY Brake Replacement

If you’re mechanically inclined, you can swap out brake pads with relative ease. Car brake replacement requires some specialized tools and supplies before beginning. If you don’t have these supplies on hand, many tool rental shops have them.

• New Brake Pads
• Brake Fluid
• Gloves
• Jack
• Jack Stands
• Lug Wrench
• Wrench
• C-Clamp
• Wire Brush
• Penetrating Grease

First, you want to loosen the lug nuts before raising each wheel and supporting that corner of the car with the jack stands. Loosen the bolt on one end that hold the caliper in place, then pivot the caliper to access the brake pad, which you pull out.

If you’re having trouble loosening the bolts, use the wire brush to remove surface rust, or apply penetrating grease to the threads, being careful to not spray the brake disc. Compress the pistons on the calipers with the C-clamp so they’ll clear the new, thicker brake pad. Insert the new pads into the calipers, then reassemble everything by reversing the order you followed to take it all apart.

Most people just don’t think about their car’s heater until they’re in need of auto heating repair. After all, you basically flip a switch and hot air comes out of the vents. It’s a great feature everyone takes for granted, which is why having problems with it can be infuriating – especially during the winter!

The good news is you can turn to car heater repair shops and have the problem fixed. Depending on what’s wrong, you might be on your way in a short while. Trying to repair the heater yourself, unless it’s an incredibly basic problem, isn’t advisable. The level of difficult for those kinds of repairs is well beyond the mechanical skills or expendable time on most people’s hands.

How do Car Heaters Work?

The hot air you feel blowing through the air vents originates in something called the heater core. It’s basically like a small radiator embedded under the dash. Hot coolant is transported from the engine to the heater core, where a fan helps extract some of the heat, blowing it into the cabin. This is why people say if your engine is overheating, you should roll down the windows and turn the heater all the way to full blast.

When you first get into your car on a cold winter morning, the air coming out of the vents isn’t hot. This is because there literally is no coolant running to the heater core. As you drive, the engine heats up, which increases the coolant’s temperature to the point it’s ready to be sent to the heater core. As it does, the air coming through the vents heats up as well.

Do Heaters do Anything Besides Heat?

Your car’s heater system also affects the defroster. Vents aimed at the windshield (and on some models the back window) blow hot air directly onto the glass. Their purpose is to remove any fog, snow, or ice buildup. Without the defroster, you might have a hard time seeing, especially at night.

Since the defroster is also dependent on the heater core working properly, you should get any heater system issues fixed immediately. Losing the defroster because of a problem with the heater system can actually cause a wreck, putting you and fellow drivers in serious danger.

Common Car Heater Problems

Because the heater works by using coolant that’s been heated up by the engine, a coolant level that’s too low can cause serious issues. Sometimes, fixing the problem might simply require topping off the coolant to a normal operating level. You need to be careful about doing this yourself.

Opening up the radiator or pressurized overflow reservoirs when the car is even a little hot can be catastrophic. The coolant can be incredibly hot, spewing out and burning you. Always heed any warnings printed on the cap of whatever you intend to open. If you’re not sure what you’re doing, it’s best to not risk serious injury and call a professional for auto heating repair.

Other problems could have to do with the heater core, or the hoses that transport coolant to and from the car’s coolant system. Replacing old, cracked hoses should only be done when the engine is cold. There’s a slight chance the fuse your car’s heater runs on could be blown. Checking the fuse is a quick and easy solution for auto heating repair, as is replacing it, if needed.

What About Plug-In Heaters?

You might be considering a plug-in heater for your car instead of repairing problems with the built-in heater. One factor to consider is that plug-in heater can put an extra drain on your car’s battery during the time of the year when cold weather puts a strain on them. You’ll also need to find a spot to place the plug-in heater, which can be tricky depending on the car’s interior layout.

Just as important is the fact that the hot air from this type of heater might not reach the backseat quickly, especially if your car has rear air vents, making trips uncomfortable for your backseat passengers.

Most importantly, plug-in heaters don’t defrost windows, so you could still suffer from serious visibility issues.

Many people are attracted to hybrid and electric cars for a variety of reasons. Cutting down on tailpipe emissions, fewer to no stops at gas stations, and other advantages can be enjoyed by anyone willing to take the plunge. One area of concern that quite a few shoppers have is what kind of maintenance hybrids and electrics require. After all, maintaining hybrid cars and fully-electric vehicles can seem daunting, considering how technologically advanced they are. This guide to maintaining an electric or hybrid car will help you feel less intimidated!

Guide to Maintaining an Electric or Hybrid Car

Electric and hybrid cars have many of the same components as standard gasoline automobiles, so most areas which need repair are similar to your typical vehicle.

Engines

Remember that hybrid cars still have a gasoline engine, which works in tandem at least part of the time with one or more electric motors. That means the usual maintenance items you would expect with a traditional vehicle will be required on electric hybrid vehicles, such as oil changes, timing belt replacements, valve adjustments, etc. Of course, the amount of maintenance required and the cost varies from one model to the next, so it’s a good idea to check out how different options compare before you make a final purchase decision.

The owner’s manual in your vehicle, or the manufacturer’s website, should offer detailed instructions on how to care for the engine. A maintenance schedule should be part of the instructions, taking the guesswork out of when you should have certain items addressed by a technician.

There are also diesel electric hybrid car models on the market. Like the gasoline versions, these require the same kinds of maintenance items as the traditional version of the same vehicle.

One big advantage of hybrid cars is that the gasoline or diesel engine isn’t put under as much strain, when compared to non-hybrid versions of the same model. This means wear and tear on the engine is less, so if maintained properly it should continue running without any major problems far longer.

Motors

Both hybrid and electric vehicles come with at least one electric motor. There are few moving parts in them, a stark contrast with gasoline engines. That means less can break or go wrong, so little maintenance is required. When components do wear out, it’s far easier for a technician to replace them, so the cost is quite a bit lower.

Hybrid-Specific Components

When looking at hybrid car repair, you might be surprised to find there’s really nothing beyond what you’d do with a traditional vehicle. The manufacturer has a checklist of items that should be inspected at certain mileage intervals, with many of them matching what you’d do with any other car. A qualified technician who’s familiar with your specific vehicle make will know exactly what to look for in terms of potential problems, catching them before they can develop into something serious.

Little of the regular maintenance items involve hybrid-specific components, although how much this is true depends on the exact hybrid model you own. Unlike gasoline engines, batteries and electric motors don’t need oil changes, valve adjustments, or even new timing belts on a regular basis. In other words, you’ll actually need to spend less to maintain the hybrid system on your car, making it a wise financial move.

Coolant

Hybrid and electric cars for the most part use coolant, just like traditional vehicles. Not only do hybrid cars have an internal combustion engine to keep below dangerous temperatures, it also must regulate the temperature of the battery pack. This means sending the coolant over a larger area of the car, which requires a more complex setup.

You must maintain the liquid at an ideal level, otherwise the car won’t run correctly. In some extreme cases, a vehicle could suffer serious damage from overheating because of a lack of coolant. It’s a good idea to check the coolant level once a week, or more if you’re driving in especially hot weather.

Just like other vehicles, hybrid and electric cars need coolant changes at regular intervals. Because of the more complex nature of the cooling system, this particular maintenance item can be more involved. That translates into more expensive, because techs must perform more work each time. The good news is the coolant usually doesn’t have to be replaced any more often than in other vehicles.

Batteries

Some people have been concerned about buying a hybrid or electric car because of the potential cost of replacing batteries. It’s an honest worry, considering that with traditional cars an owner will replace the battery multiple times.

Unlike the batteries in traditional cars, the batteries in electric hybrid vehicles are large, complex and quite expensive. It’s understandable that anyone would be worried about replacing such a costly component, especially if it needs to be replaced every few years.

The fact is that may hybrids and electric vehicles run for well over 150,000 miles on the original battery pack. There are electrified taxis in cities such as New York and San Francisco that have been able to go well over the 200,000-mile mark without replacing the battery. In other words, you don’t really need to worry about this any more than you need to worry about replacing the engine in a traditional car.

Thanks to an automotive technology called shocks, we enjoy a more comfortable and controlled ride. It wasn’t always like that, because back when cars were still relatively new machines the ride was bouncy and rough.

Automobile Shocks: How They Work

The common misconception is that car shock absorbers actually support the vehicle’s weight, but that’s far from the truth. What they really do is control any movement in the suspension and springs. To get a little scientific, shocks do this by taking the movement or kinetic energy and converting it into heat. That energy is stored inside the shocks’ hydraulic fluid, before escaping into the surrounding air.

If you were to cut a car shock in half lengthwise, you’d see a cross section of how it works. There’s a long piston rod with a piston on one end, which sits flush with the walls of the shock cylinder or pressure tube. Hydraulic fluid sits inside as well.

When the car drivers over a pothole or bump, the piston is forced up and down in the pressure tube. Small holes in the piston, called orifices, allow the hydraulic fluid to pass through. Because the flow is only slight, thanks to the size of the orifices, the shocks are able to absorb the energy transferred from the suspension and vehicle springs.

All shocks provide greater resistance the faster the suspension bounces. This allows for adjustments based on different surfaces, making for a more comfortable ride quality on rough pavement Of course, not all shock absorbers are made equal. Some provide more resistance than others, thanks to factors like the size and number of piston orifices.

Automobile Shocks: Recognizing Trouble

Now that you have a basic understanding of what shocks are and how they work, you’re ready to learn the different warning signs that they need to be replaced. Failure to replace worn shock absorbers not only means you’ll be enduring a rougher ride; it can also lead to damage as the undercarriage comes into contact with the road. That’s why you should always be watching for these warning signs, the taking action as soon as they crop up.

You should know that shocks don’t just suddenly wear out. It happens gradually over time, so you might not realize what’s going on until they’re pretty far gone. That’s why when you’re in doubt, have a trained auto tech take a look to see if the shocks are bad enough to justify swapping them out, preventing serious damage.

Also, know that you can’t just replace your shocks after a set number of miles. How quickly they wear depends on how you drive your car, what the roads are like where you live, etc.

One of the telltale signs of worn shock absorbers is a bouncier ride. If you notice that when you go over bumps in the road, your car dives up and down wildly, that means you need to have the shocks inspected. The problem could also manifest when you drive over a series of small bumps or ripples in a road, with the traction control system light flickering on in the instrument cluster as one or more wheels literally bounces up and down while struggling to attain enough grip.

Most people realize that bottoming-out is a bad thing, so that’s perhaps the most obvious sign of worn shocks. The problem usually first manifests when you go over railroad tracks or have trouble with steep driveway skirts.

If you hear a strange sound whenever the car goes over a bump, that also can signal trouble. As the shocks age and reach the end of their life, they can begin creaking, popping or making other noises that let you know it’s time to have them replaced.

When you hit the brakes hard, like during a panic stop, your car might lean forward slightly before coming to a complete stop. If the front end dives down hard, that can be a sign of worn shocks. The same is true with what’s called acceleration squat. If when you accelerate hard, the back end of the vehicle sinks down, that’s not a good sign.

Too much body lean is another indication something’s wrong. When they’re in good condition, a vehicle’s shocks regulate at least some of the body lean, which boosts handling ability and comfort when navigating through turns.

Perform This Simple Test

You can perform a simple test at home to tell if the shocks on your vehicle are worn enough that they need to be replaced. Push down as hard as you can at each corner of the car, then let go abruptly. If after you release the vehicle it keeps bouncing, you likely need new shocks.

T3 Atlanta

The only way to tell for sure if a vehicle’s shock need to be replaced is to have a highly skilled technician look at them. At T3 Atlanta we have all of the necessary equipment and training to take great care of your car.
