2	Brake Hose Fitting Gasket (Qty: 2) Procedure: Discard the brake hose fitting gaskets and install new gaskets.
3	Brake Hose Fitting Tip: Plug the brake hose fitting to prevent brake fluid loss and contamination.
4	Brake Caliper Guide Pin Bolt (Qty: 2) Procedure DO NOT use any air tools to remove or install the brake caliper guide pin bolts. Use hand tools ONLY. Install an open end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolts. DO NOT allow the open end wrench to contact the brake caliper. Allowing the open end wrench to contact the brake caliper will cause a pulsation when the brakes are applied. Ensure the brake caliper guide pin seal is fully seated in the groove of the brake caliper guide pin and the guide pin slides freely in caliper bracket bore. Tighten: 100 N.m (74 lb ft)
5	Brake Caliper Procedure Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding (Manual) or Hydraulic Brake System Bleeding (Pressure) . After the installation is complete and with the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance. Slowly release the brake pedal. Wait 15 seconds, then repeat steps 2-3 until a firm brake pedal is obtained. This will properly seat the brake caliper piston and the brake pads. Fill the master cylinder to the proper level. Refer to Master Cylinder Reservoir Filling .
