1. Corrosion: Brake calipers are exposed to moisture, road salt, and other corrosive elements that can cause them to rust and deteriorate over time. Rust can build up on the caliper's piston, preventing it from moving freely and causing the brake pads to drag on the rotors.
2. Seized Piston: The piston inside the caliper is responsible for applying pressure to the brake pads. If the piston becomes seized due to corrosion or lack of lubrication, it will not be able to move properly, leading to brake failure.
3. Leaking Seals: The seals around the caliper's piston can become worn or damaged, allowing brake fluid to leak out. This loss of fluid will reduce the caliper's ability to apply pressure to the brake pads, resulting in decreased braking performance.
4. Excessive Heat: Brake calipers can overheat due to excessive braking, especially in high-performance vehicles. Overheating can cause the caliper's seals to melt or fail, leading to brake fluid leaks and reduced braking performance.
5. Improper Installation: If a brake caliper is not installed correctly, it can cause premature wear and tear. For example, if the caliper is not properly aligned with the brake rotor, it can cause the brake pads to wear unevenly or become damaged.
