Bad Brake Caliper Symptoms You Shouldn't Ignore

Bad Brake Caliper Symptoms You Shouldn't Ignore

Uneven brake pad wear

Uneven brake pad wear is a sign that your brakes are having trouble. It can be caused by a variety of things, including a dirty brake caliper, worn brake pads, or a non-concentric brake. It can also indicate that your brake pad sensor needs to be replaced. Luckily, this symptom usually goes away once you clean your car's brakes.

Grinding or growling noises

If you're experiencing grinding or growling noises from your brakes, don't ignore them. This noise can mean that you need to replace your brake pads. You can hear the noise in your car even with the windows open or if you're listening to the radio or air conditioning.

Vibrations in steering wheel

Vibrations in the steering wheel can be caused by several different automotive problems, but almost always the culprit is your brake caliper. These discs clamp down on your brake pads to slow the car. If they're worn, they can cause the caliper to vibrate and cause the steering wheel to shake.


A squealing brake caliper can be a symptom of a serious brake problem. You should contact a mechanic if the noise persists after these steps. In some cases, the noise can be reduced by using aftermarket brake pads. Some parts are specially designed to reduce noise and squeals. You can also try applying anaerobic adhesives to the brake piston, according to Popular Mechanics. However, this may not be the right solution if the problem is more serious.

Guide pin corrosion

Guide pin corrosion is one of the bad brake caliper symptoms you shouldn't ignore. When changing the brake pads, it's important to inspect the guide pins as well. To check, lift the car and remove the caliper, exposing the guide pins. In most cases, there are two guide pins, which are surrounded by a rubber housing.

Unbalanced braking

If your car pulls to one side when braking, it may be a sign that your brakes aren't applying enough pressure. This can be caused by air or moisture getting into the braking system, or a caliper or hose issue. In either case, unbalanced braking should not be ignored.

Brake fluid leaks

Brake fluid leaks are one of the most serious brake problems. If you notice fluid leaking from your car, it's important to take it to a mechanic right away. A brake fluid leak can lead to complete failure of your brakes, which could be dangerous.

Brake light on

If your brake light is on, it's a sign that there's a problem with your brakes. The most common reason for this is low brake fluid. However, it can also be caused by a variety of other issues, including a faulty sensor or an issue with the braking system itself. If your brake light is on, it's important to have your car checked out by a mechanic.


Bad brake caliper symptoms shouldn't be ignored because they could lead to serious problems. If you're experiencing any of these symptoms, it's important to take your car to a mechanic and have it checked out. Ignoring these problems could result in complete failure of your brakes, which could be dangerous.
