Brake calipers, although robust components, can experience some failures over time due to normal wear and tear, driving conditions, or lack of maintenance. Here are some of the most common failures that can affect brake calipers:
Wear and fluid leakage.
Brake pads, which are an integral part of the braking system, can wear out over time. This wear is normal, but if not replaced in time, it can lead to more serious problems, such as damage to the caliper.
In addition, brake calipers operate with hydraulic fluid. Leaks in the hydraulic connections or in the caliper itself can reduce the efficiency of the braking system and require repair.
Piston seizures and corrosion
Brake dust, dirt and moisture can build up inside the caliper, causing clogging or corrosion. This can affect the smooth movement of the pistons and reduce braking performance.
As such, the pistons inside the caliper may stick due to dirt or corrosion build-up. This can lead to uneven braking or, in extreme cases, total loss of braking on a wheel.
Uneven wear and braking noises
If the brake pads wear unevenly, it may indicate a problem in the caliper. This may be due to a piston that is not moving properly or uneven wear of the pads.
Also, squeaking or crunching noises when braking may indicate caliper problems, such as pistons that do not move freely or worn pads.
Overheating and incorrect calibration due to impact damage
Finally, excessive or prolonged braking can cause brake calipers to overheat. This can affect the efficiency of the system and damage the internal seals.
Incorrect caliper calibration can lead to uneven braking, resulting in uneven pad wear and reduced braking efficiency. In addition, shocks or impacts to the calipers, whether from road conditions or accidents, can damage the structural integrity and performance of the calipers.
