While servicing disc brakes, you must use good quality name brand pads of national repute. To determine the type, inspect the caliper with the wheel removed. It can either have sliding type caliper or floating type caliper. To reduce the risk of spilling on painted surfaces, remove the cap to the master cylinder reservoir in the sliding calipers and siphon out approximately half the fluid. Loosen the lug nuts on the front wheel, securely raise the vehicle on jackstands, then remove the wheels, working on one brake assembly at a time. In the case of sliding calipers, the two spigot pins should be removed from the stopper plugs and these should be pulled out along with the stopper plugs and pad support plates. If necessary, remove the top bolt to hang the caliper out of the way. Remove the pads from the caliper bracket. Separate the outer pad from the shim and remove the pad clips. Assemble new pads with the shim on the outer pad, insert piston with wood dowel or hammer handle and lubricate contact with multi-purpose grease. Place the caliper assembly over the new pads and refit the pad support plates, stopper plugs and spigot pin. For floating calipers, first, use a large C-clamp to push back the piston. Next, remove the lower mount bolt and rotate the caliper to get to the pads. Detach any anti-rattle springs, remove the brake pads and shims from the bracket, and clean the surfaces. To install the pads and shims, install the new retaining clips and coat the shims with disc brake grease. As the caliper is installed, lower the vehicle, Press the pedal for the pads to touch the disc, and check the fluid level in the master cylinder. Make sure to perform a careful road test before normal use.
