Begin by checking the level of the brake master cylinder reservoir; if the level fall between the maximum and minimum points, there is no need to take out any fluid out. Raise and support the vehicle, remove the tire and the wheel assembly. The large c-clamp compresses the caliper piston into the caliper bore, but make sure you do not exceed 1mm (0.039 in) of piston travel lest you create a compromise to the internal adjusting mechanism. After the compressing the piston, off the c-clamp, as well as the lower brake caliper guide pin bolt, while supporting the brake caliper with a heavy mechanic wire to avoid straining the hydraulic flexible brake hose. Rotate the caliper upside and pull out the brake pads and Brake Pad retainers from the brake caliper mounting bracket . Check the components of the brakes for worn and corroded components and replace the damaged parts. Inspect the Brake Caliper Piston boot for wear and replace if it appears to be worn. Twist the Brake Caliper Piston into the bore using a piston installation tool; install Brake Pad retainers and brake pads on to the mounting bracket. Put the brake caliper in the direction over the brakes and into the caliper bracket, install the brake caliper guide pin bolt and tighten it to 35 nm (26 lb ft). Replace the tire and wheel assembly, lower the vehicle and slowly press the brake pedal about 2/3 of its way, then release. With the engine off, do this. Do this for as many times as it takes to obtain a firm pedal that should properly seat the caliper pistons and brake pads. Finally, top up the brake master cylinder reservoir to the right level, apply and release the park brake lever four times, and burnish the pads and rotors.
