CAUTION
In the following step, do not use a
sharp tool to remove the dust and pis
ton seals from the caliper cylinder.
Sharp tools could damage the cylin
der surface. The caliper will have to
be replaced if the cylinder surface is
damaged.
4. Use a piece of plastic or wood to carefully re-
move the dust seal (A,
Figure 30
) and the piston
seal (B) from their grooves in each caliper cylinder.
Discard both seals.
5. Clean all caliper parts and inspect them as de-
scribed in this section.
NOTE
Never reuse the old dust seals or pis
ton seals. Very minor damage or age
deterioration can make the seals use
less.
6. Coat the new dust seal and piston seal with fresh
DOT 4 brake fluid.
7. Carefully install the new piston seal (B,
Figure
30
) and dust seal (A) into the grooves in the caliper
cylinders. Make sure the seals are properly seated in
their respective grooves.
8. Coat the pistons and caliper cylinders with fresh
DOT 4 brake fluid.
9. Position each piston with the open end facing to-
ward the brake pads (
Figure 31
) and slide the pis-
tons into the caliper cylinders. Push the pistons in
until they bottom in the cylinders.
10. Install the pad spring. Make sure the spring is
completely seated in the bottom of the caliper body
as shown in
Figure 27
.
11. Install the caliper and brake pads as described
in this chapter.
Inspection
1. Clean all parts, except brake pads, with clean
DOT 4 brake fluid. Place the cleaned parts on a
lint-free cloth while performing the following in-
spection procedures.
2. Inspect both seal grooves (
Figure 32
) in each
cylinder for damage. If they are damaged or cor-
roded, replace the caliper assembly.
3. Inspect the walls (
Figure 32
) in each cylinder
for scratches, scoring or other damage. If there is
rust or corrosion, replace the caliper assembly.
