REMOVAL & INSTALLATION
See Figure 1
- Loosen, but do not remove the reservoir cover.
- Jack up the car and remove the wheel and tire.
- Using a punch, remove the two pins which retain the disc brake pads in the caliper.
If the pads are to be reused, mark the pads to insure that they are reinstalled in the same caliper and on the same side of the disc. Do not invert the pads. Changing pads from one location to another can cause uneven braking.
- If the pads are not going to be reused, force a wedge between the disc and the pad and pry the piston back into the caliper as far as possible.
- Using a suitable brake parts cleaner, rinse away the brake dust. Pull the old pad out of the caliper and insert a new one, taking care to note the position of the retaining plate.
On ATE and many Teves disc brakes, before inserting the brake pads, make sure the relieved part of the piston is in the correct position to accept the retaining plate. In the illustration, the sides of the retaining plate "b" fit into the relieved area while the circular part of the plate "a" fits in the piston's center. On some Type 2's and other models, the retaining plate is simply a flat piece of metal with two notches which fit into the relieved areas in the piston. The relieved side of the piston should face against (away from) the rotation direction of the wheel when the car is going forward.
- Now insert the wedge between the disc and pad on the opposite side and force that piston into the caliper. Remove the old pad and insert a new one.
- If the old pads are to be reused, it is not necessary to push the piston into the caliper. Pull the pads from the caliper and reinstall the pads when necessary.
- Install a new brake pad spreader spring and insert the retaining pins. Be careful not to shear the split clamping bushing from the pin. Insert the pin from the inside of the caliper and drive it to the outside.
- Pump the brake pedal several times to take up the clearance between the pads and the disc before driving the car.
- Install the wheel and tire and carefully road test the car. Apply the brakes gently for first 500 to 1,000 miles to properly break in the pads and prevent glazing.
