Both front and rear disc brakes adopt this technique. Start with unbolting the front wheel lug nuts, lifting then the front part of the car and placing it on jackstands, and engaging the parking break. Once again, if only working on the front wheels of the car, then remove the front wheels; otherwise, if working on the rear wheels which have discs, then remove the rear wheels. After that, drain out approximately, two thirds of the brake fluid from the master cylinder reservoir and dispose, placing a drain pan under the brake assembly and cleaning the caliper and the surrounding area using the brake system cleaner. The C-clamp should then be employed to force the piston back into the bore to make enough room for the new brake pad; when pressing the piston remember not to give the master cylinder much fluid; if this has to be done it should be decanted in order to avoid spilling much of it. If pads have been remove, then one should check for the brake fluid leakage and whether the piston boot has been ruptured or not, and if yes then either overhaul or replace the caliper, and while inspecting the
Brake Disc in case if machine is required then one should follow certain procedure. Examining and removing if essential, the caliper guide pin bolts should be cleaned and checked, for signs of corrosion; if severely corroded or damaged, then it was replaced before being tightened to the required torque. Place the brake pads on the other wheel and fit the wheel and then raise the car and over tightening the nuts to the standard torque. The reservoir should be filled with brake fluid, then to ensure that pads are seated on the disc, the brake should be pumped severally before the level of the brake fluid is checked again. Last but not the least, the brakes should be checked thoroughly for its working before it is put to normal use, one must not use more force while applying the brakes until the brake pads are applied several times so that they sit correctly on the disc.
