Brake calipers hold the brake pads and force them against the brake rotors when you push on the brake pedal. The calipers move in and out on slide pins, which must remain free of corrosion, excessive brake dust and road dirt. Dirty or unlubricated caliper slide pins are the No. 1 cause of sticking brake calipers. When performing brake pad replacement, always make sure you take care of the caliper slide pins in order to avoid a sticking brake caliper.
