One should be careful not to depress the brake pedal when the caliper is removed. Whenever non-screwed, the caliper guide pin bolts should be replaced with new ones. Start by loosening the bolts of the rear wheel, chocking the front wheels, lifting the rear of the car, and firmly holding it on jackstands, then removing the rear wheels. Leverage the parking brake to release the lever and back the parking brake cable adjusters to allow the maximum freeplay in the cables and be sure the two caliper parking brake lever are clear of their stops. Unscrew caliper mounting bolts keeping the guide pins fixed by holding with an open-end wrench and discarding the old mounting bolts that are needed to install new ones. Unhook the caliper off the brake pads and hold it by a piece of wire length of wire tied to the suspension strut without any unsupported hanging on the flexible brake hose. Take off brake pads in the caliper mounting bracket and ensure that the guide pin slides easily and the rubber guide pin boots are not worn before lubricating them with high temperature brake grease in case they do not show any form of wear. Wipe the caliper and piston with brake system cleaner and check the dust seal and piston, searching damage and leaks, replacing the caliper (where needed). In order to fit the new brake pads, completely insert the piston into the caliper bore by rotating it clockwise with a retraction tool or needle-nose pliers so that excess brake fluid will be expelled through the caliper bleed screw. Take the protective sheet off heat plate backings and fit in the pads in the mounting bracket with the friction material facing the
Brake Disc. Slide the caliper back in the same order as before over the pads with pad anti-rattle springs in place in the right spots, and install new mounting bolts and tighten them to the required torque without turning the guide pins. Wipe the same procedure on the other rear brake caliper then repeat the pedal pressing on the brake pedal just to make sure that the pads and discs are firmly touching, and that the discs are moving freely once again when normal pedal feel is regained. Install the wheels, wheel bolts, and adjust the parking brake cables, lower vehicle to the ground, and also tighten the wheel bolts to the required torque. Lastly, top up the level of braking fluid when required and thoroughly test that the brakes are working well before allowing the vehicle to resume normal service.
