In this article, we’re going to outline what an uneven brake pad means and all the possible causes of uneven brake pad wear.
The brake system is one of the most important components of your vehicle because of the role it plays in keeping you and other road users safe. That is one of the major reasons you should maintain the braking system properly so that it will be able to walk properly as it is designed to.
The braking system employs some components and these components must be well protected.
Brake pads are designed to fit inside your brake calipers and clamp down onto the rotors, which are manufactured to be the source of friction and provide you with stopping power.
Brake pads are one of the consumable categories in your vehicle parts. The brake pad and other components of your brake system wear down over time after use for a long time, and they need replacement.
That’s why it is very important to maintain or monitor the amount of brake pad material that remains on your brake pads so that it will be able to keep you safe on the roads.
The rate of wear or uneven brake pad depends on a wide range of variables, your brake pad, driving style, condition of your brake rotors, or if your brake calipers are working as they’re supposed to.
There are numerous signs that you need to look out for because they indicate that your brake pads are reaching the end of their service life or wearing unevenly.
If your brake pads are on their way out, then you will begin to feel them not working as well as they used to. Another popular sign that you may experience is the squealing sound when you hit the brakes.
Vibration under the braking components is also one of the popular signs of uneven brake pads.
What Does It Means
Do you want to know the meaning of an uneven brake pad? If yes, it usually occurs as a result of caliper failure. The caliper contains a piston that presses on the brake pads so that it will be able to stop the vehicle. When the driver releases the brake pedal, a seal inside the caliper pulls the piston away from the pad.
Uneven brake pads indicate the common cause of unevenly worn brake pads is Disc Thickness Variation or DTV. Any difference in the thickness of your discs will cause the brake pad to wear down differently over time.
Causes Of Brake Pad Uneven
1. Caliper Failure
Caterpillar failure is one of the common causes of brake pads uneven. In case you have noticed your car’s brake pads wearing unevenly, it could be a caliper failure. Brake pads are manufactured to wear down evenly so they will be able to provide even braking pressure for the driver.
Uneven pad wear can develop if any metal-on-metal contact in the brake system. Luckily, with proper maintenance, it is possible to avoid this.
Have you ever noticed that your brake pads are wearing unevenly? Then, there is a good chance that your car is out of alignment. Misalignment is one of the common causes of uneven brake pad wear. Misalignment may cause a lot of problems, and uneven brake pad wear is just one of them.
Misalignment is designed to make the front wheels pull to one side or the other when braking and can result in uneven wear on the pads. This is because if one tire wears faster than the other, your vehicle won’t be able to turn properly, and it will cause more friction on the side of your brakes. It usually causes squealing noise and an unbalanced feel while driving.
3. Slide Pins
The slide pins it’s also one of the major causes of uneven brake pads. It is designed to keep your brakes and wheels connected so that they can become corroded, preventing the caliper from moving back and forth with each revolution of tires on rims.
You will see signs of a decrease in stopping power as this happens; if it lasts long for pads to wear down too much, there could be a problem.
It is advisable to use a wire brush (or rag) to clean the issue before applying grease. Immediately after you have cleaned it, make sure not to overspray any important areas where rust may begin to build again.
4. Sticky Caliper Pistons
Debris or rust that enters any of the pistons can cause sticky brake calipers, in case your piston does not slide smoothly, the brake pad will become stuck to the rotor. It is common for a caliper that is jammed to wear down the brake pads.
One of the most common reasons for uneven brake pad wear is the caliper issue. Pressure to the piston is for not being applied or not being released properly when a caliper fails to engage.
Likewise, if the piston is being ejected, but refuses to return. A bad seal or piston, or corrosion on the piston can cause it to bind against the internal cylinder, which is the cause of either of these symptoms.
If you can hone the cylinder; clean or replace the piston; then replace the seal to fix it. It’s known as rebuilding the caliper, it’s an easy and inexpensive method of fixing uneven brake wear on a car. But, if you don’t have the right equipment or knowledge, then you need to take it to your mechanic so that they will be able to help you to fix it properly.
