Important: 

   • Install all new components included in the repair kit used to service this caliper.
   • Lubricate rubber parts using clean brake fluid in order to ease assembly.
   • Do not use lubricated compressed air on brake parts. Damage to rubber components may result.
   • If any hydraulic component is removed or disconnected, it may be necessary to bleed all or part of the brake system.
   • Replace the brake pads in axle sets only.
   • The tightening specifications are for dry, non-lubricated fasteners.
   • Perform service operations on a clean bench, free from all mineral oil materials.

This caliper contains a single bore. The caliper is mounted to the steering knuckle using 2 mounting bolts. Hydraulic pressure, created by applying the brake pedal, is converted by the caliper to a stopping force. This force acts equally against the caliper piston and the bottom of the caliper bore in order to move the piston outward and in order to move (slide) the caliper inward. This results in a clamping action on the rotor. The clamping action forces the linings against the rotor, creating friction in order to stop the vehicle.
