Take off the cap for the brake fluid, and then, drain the existing liquid about one-and-a-half inches or 40mm and dispose it effectively. Lose the wheel lug nuts, lift and safely jack up this car, then, place it on suitable stands before removing the wheels. Place a drain pan beneath the brake caliper assembly and wash the disc together with the caliper with the brake system cleaner, guaranteeing that you do this without the use of compressed air. Look at the
Brake Disc and if it has to be machined, remove the disc together with the calipers and pads. When it comes to fixed calipers, please refer to the pad replacement illustrated here, where the caliper is dismantled and retaining clips, shrouded anti-rattle springs and pad pins pulled out are removed. The brake pads need to be pushed inward to force the pistons back, after that backplates and contact surfaces have to be cleaned, new pads have to be lubricated and put back on with shims if needed. For floating calipers, retract the piston back into the bore with the help of C- clamp; make sure that the master cylinder's fluid does not spill over. Pull out the caliper, pads and the support plates but while replacing the parts that have worn out and lubricant the new ones before fitting. Replace the new pads as the next step after removing the wheel and lug nuts, put back the wheel and the lug nuts, lower the car, and finally, tighten the lug nuts. Crank the engine and apply the brake pedal several times for the pads to contact the discs, then inspect brake fluid level, and add it if necessary, for proper braking before operating the vehicle.
