First, check the master cylinder reservoir and filler caps, next remove the filler cap and drain about 1/4 fluid with a clean suction gun. Pull the car up with a jack and afterward remove the front tires. Put a C-clamp at the bottom of each piston in the bore, with the clamp frame on the back of the caliper and the clamp screw next to the outboard brake shoe. Insert a screwdriver between the caliper spring and its clip, then pull up on the spring and move it out of the holes. Next, remove both slide pins, the caliper and the brake shoes. To remove the outboard brake shoe, pull one end of the spring away from the caliper, lift and swivel the shoe outwards. Tip the inboard shoe away from the caliper so the retainer spring passes over the caliper piston, but don't leave the hose to bear the caliper weight. The adapter ledges should be cleaned with a wire brush and then coated thinly with high-temperature grease before installation and only replace the slide pin bushings if they are damaged. Fix the inboard shoe, with the retainer spring securely in the piston and then insert the outboard shoe, with the retainer spring placed in the caliper. Set the caliper and brake shoes on top of the rotor within the adapter and after hand-turning the caliper slide pins, tighten them securely to 30 Nm (22 ft. lbs.). Cover one caliper hole with the spring and put the other end under the adapter, holding down the spring while you use a screwdriver to seat the spring in the caliper. Your last step should be to mount the wheels and tires, let go of the support stand, lower the vehicle, pump the brake, check the brake fluid and press the brake pedal to confirm it's firm.
