braking system Brake Caliperss in GMC Envoy car's function is to clamp the brake pads against the rotors, and to stop the motion of the car. The action is accomplished by hydraulic pressure exerted on the brake fluid each time the brake pedal is depressed; the caliper's pistons can be of plastic, aluminum or chrome plated steel. GMC Envoy models utilize two primary types of brake calipers: stationary and variable bearer types with the latter being split in floating and non-floating. Semi-floating calipers are screwed into position, have four or more pistons on each side of the rotor and are more effective than floating piston calipers but more expensive. Sliding calipers, or floating calipers, use only one piston to slide the caliper to either side of the rotor and apply pressure, which makes this kind of caliper less complicated, but more susceptible to flaws such as sticking. It is therefore important that these differences are well understood so that the maximum level of braking on the Envoy can be achieved at all times.
