Consult with a trained technician to properly diagnose and repair the problem. However, this may not be the caliper at all. If the caliper leaks, drivers may notice an oily spot on the ground inside the tire. Modern brake systems use hydraulic pressure to operate. Leaking Brake Fluid On the Ground Inside the Tires Take the vehicle into an auto repair shop and have a trained technician take a look at the problem. If it seems that the brake pads on one side of the vehicle are thinner than the other side, it’s possible that the brake caliper is at fault. Make sure to take the vehicle into an auto repair shop as soon as possible, as a frozen or stuck caliper can eventually cause the brakes to lock up completely. This sound, if it’s due to the brake calipers and not the brake pads, will occur during driving, while brake pad issues will cause a noise when the driver applies the brakes. High-Pitched Squealing or Metalic Rubbing NoisesĪnother symptom of a sticking or frozen brake caliper is a noise emanating from the damaged part. This can happen when the brakes are applied or during normal operation. If the brake pad fails to come into contact with the rotor, the vehicle will pull away from the damaged side. In the first case, the car will pull toward the side where the damaged caliper is. If the pistons freeze up due to debris or corrosion, the brake pads will either fail to release the rotor or fail to come into contact with the rotor. If your vehicle shows any of these signs of brake caliper problems, bring it into Ron’s Auto & RV for proper diagnosis and repair!ĭoes the car seem to pull or steer to one side while the vehicle is in operation? The brake caliper contains pistons that move in and out due to hydraulic pressure from the master cylinder. Vehicle Pulls To One Side When Driving or Braking If the brake caliper fails, the brake pads wear out faster than normal. Unlike brake pads, which wear out over time with normal use, brake calipers are supposed to last the life of the vehicle. The brake caliper squeezes the brake pads in toward the metal disc until the vehicle slows. The brake fluid then activates the brakes, forcing the brake caliper to squeeze the disc and slow the vehicle. Then, the brake booster transmits the force to a piston inside of the master cylinder, which forces brake fluid out of itself into the brake lines that go to each wheel. Press on the brake pedal, then the brake booster amplifies that force. When motorists press the brake pedal with their foot, the vehicle turns kinetic energy (the car’s wheels rotating) into heat energy (by way of friction). Having brake caliper problems? To understand the function of a brake caliper, motorists first need to understand how their vehicle’s disc brakes work.
