Removal

• Before proceeding, refer to => [ Safety Precautions ] Service Precautions.

- Using a brake pedal holding tool, depress the brake pedal past its first one inch (25 mm) of travel and hold it in this position. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid to drain out of the master cylinder reservoir when the lines are opened.

- Raise and support the vehicle.






- Remove the wheel mounting nuts (3), then the tire and wheel assembly.






- Remove the banjo bolt (3) connecting the brake flex hose (2) to the brake caliper (1). There are two washers (4) that will come off with the banjo bolt. Discard the washers.







When removing or installing a caliper guide pin bolt, it is necessary to hold the guide pin stationary while turning the bolt. Hold the guide pin stationary using a wrench placed upon the pin's hex-shaped head.

- Remove the two brake caliper guide pin bolts (2, 3).

- Slide the disc brake caliper (4) from the disc brake adapter bracket (1) and brake pads and remove.

Installation

- Completely retract the caliper piston back into the bore of the caliper. Use a C-clamp to retract the piston. Place a wood block over the piston before installing the C-clamp to avoid damaging the piston.







Use care when installing the caliper (4) onto the adapter bracket (1) to avoid damaging the guide pin boots.

- Install the disc brake caliper over the brake pads on the brake caliper adapter bracket.

- Install the banjo bolt (3) connecting the brake flex hose (2) to the brake caliper (1). Install new brake hose washers (4) on each side of the hose fitting as the banjo bolt is guided through the fitting. Thread the banjo bolt into the caliper and tighten it to 24 Nm (18 ft. lbs.).
