Brake Calipers apply the pressure required to the brake pads which grip the brake discs and slow or stop the vehicle. Over time the heat caused by on off braking can cause the brake caliper to rust and corrode, especially in atmospheric conditions.
Common signs your brake calipers gone bad include, vehicle pulling to left or right, smells of burning rubber and vibration when applying the brakes. Before you rush out to replace your brake calipers, check the fluid levels of the master cylinder and wear on the brake pads are not the cause of the issue.
A malfunctioning disc braking system is highly dangerous and an MOT failure which cannot be ignored. If your brake caliper has reached the end of it’s life cycle, it can be easily replaced at low cost with moderate mechanical knowledge.
