A trained technician raises your vehicle on an approved automotive life, removes the wheels to gain access to brakes, removes the brake caliper and then removes the brakes pads, inspects the rotors for signs of damage or excessive wear, inspects the brake caliper and brake hoses for damage and leaks, adjusts the brakes as necessary, cleans and lubricates all sliding and mounting points between the brake caliper and the caliper mounting apparatus, reinstalls the wheels and torque the lug nuts to the vehicle manufacturer’s specifications, lowers the vehicle from the automotive lift and tests for proper braking.
A floating caliper (also called a “sliding caliper”) moves with respect to the disc; a piston on one side of the disc pushes the inner brake pad until it makes contact with the braking surface, then pulls the caliper body with the outer brake pad so pressure is applied to both sides of the disc.
Floating caliper (single piston) designs are subject to failure due to sticking which can occur due to dirt, corrosion or rust build-up between the surfaces. This can cause the pad attached to the caliper to rub on the disc when the brake is released. This, in turn, can reduce fuel efficiency and cause excessive wear on the affected pad. Additional heat generated by the constantly-running pad can also lead to warping of the rotor. Regular service to brake calipers will prolong the life of your brake pads and rotors and minimize drag caused by sticking brakes.
