Do not press the brake pedal when the caliper is taken out. The first step to follow is to take out the cap in the brake fluid reservoir and it will take only a little over two thirds of the fluid which is then replaced with the cap again making sure that the spilled brake fluid is immediately washed away using clean cold water so as to avoid paint damages. Unscrew the bolts of the front wheel, elevate the front part of the car, and hold it firm on jackstands and block the wheels on the other end. Take the wheels off, one brake assembly at a time and wipe out the caliper and disc with brake system cleaner and allow to dry placing a drain pan underneath to receive any run off. Models which have Teves/Ate calipers, Unclipping the pad retaining spring, eliminating it, and exposing the caliper guide pins requires removal of the end caps on guide bushings. Remember to remove the caliper guide pins, pull the caliper off the mounting bracket and tie it to the suspension strut, to ensure that it is not hanging on its own off the flexible brake hose. Unscrew the inner pad of the caliper piston and take off outer pad of the mounting bracket. On any model using Lucas calipers, tighten the caliper mounting bolts every time they are removed, make the upper mounting bolts and lower mounting bolts unscrewed, and suspend the caliper on the coil spring. Take out the inner and outer pads on the caliper mounting plate, not forgetting the circular heat shield plate attached to the piston. Check the brake disc and then in case of machining, take the required steps to cut the disc and pads. Notice Before fitting the new pads, ensure that the guide pins insert freely in the body bushings of the caliper and lubricate them as required and clean the caliper and piston using brake system cleaner. Check the dust seal and piston, looking at them to see if they are damaged or have leaked, and replace the caliper, where necessary. To fit the new pads, insert a piston retraction tool or C-clamp to push the caliper piston into the cylinder to attach a brake bleeding tool to the caliper bleed screw. When using models with Teves/Ate calipers, cut the inner pad to fit the caliper piston, attach the outer pad to the mounting bracket, lubricate the pins of the caliper guide and push the caliper in place attaching the guide pins, which are tightened to the required torque. Install pad retaining spring and end caps and make sure that they are properly installed. In models that have Lucas calipers, the new pads should be inserted in the bracket, the caliper mounted over the pads and new mounting bolts fitted with these being tightened when the guide pins are held. Lastly, press the brake pedal several times till a firm touch is achieved, repeat the same to the other front brake caliper, attach the wheels and bolts, lower the car, and screw the bolts. Press the brake pedal several times so that it gets in touch with the disc and check the amount of brake fluid and test the brakes before getting the vehicle back on its normal service.
