First thing that you should do in order to replace the front disc brake pads should be the inspection of the fluid level in the brake master cylinder reservoir; if it is at the midway point between maximum-full point and minimum allowable level watere is not required to be drained but if it is high, drain out to the midway point. Lift the vehicle and remove the tire and wheel assembly. Push a large c-clamp over the brake caliper body against the brake caliper outer Brake Pad and compress the Brake Caliper Piston completely into the brake caliper bore with a c-clamp. Prevent using air tools for the guide pin bolts; instead use hand tools and an open end wrench to hold the caliper guide pin lined when removing the lower brake caliper guide pin bolt. Lift the brake caliper towards you and locate the Brake Pad wear sensor, in order to install correctly, and remove the inner Brake Pad and outer Brake Pad and the upper and lower Brake Pad springs. In case of replacing brake pads, dispose of the old springs; insert, the inner Brake Pad and outer Brake Pad, and return the brake caliper back into the desired position. While holding the brake caliper, the pin of the guide with the help of a back up wrench, tighten the lower brake caliper guide pin bolt to 27 nm (20 lb ft). Reinstall the tire and wheel assembly, gradually press down the
Brake Pedal to about 2/3rd of its travel distance with the engine off, then slowly release it until you work up through this cycle until afirm Brake Pedal is achieved to seat the Brake Caliper Piston and brake pads properly. Lastly, top up the master cylinder tank and burnish the brake pads and rotors.
