For 1990-2009 cars only

Important: 

   • Install all new components included in the repair kit used to service this caliper.
   • Lubricate rubber parts with clean brake fluid to ease assembly.
   • Do not use lubricated compressed air on brake parts as 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 brake pads in axle sets only.
   • The tightening specifications are for dry, unlubricated fasteners.
   • Perform service operations on a clean bench, free from all mineral oil materials.

This caliper has a single bore and is mounted to the steering knuckle with two 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 to move the piston outward and to move (slide) the caliper inward resulting in a clamping action on the rotor. This clamping action forces the linings against the rotor, creating friction to stop the vehicle.
