Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)
When removing piston with compressed air, piston can
develop considerable force and fly out of caliper bore.
Keep hands away from piston to avoid possible injury.
(00530b)
NOTE
Phenolic insulators may be loose when the brake pads are
removed, or may loosen when the pistons are expanded from
their bores. If insulators are not damaged, they can be reused.
3. See Figure 2-77. Remove pistons.
a. Place BRAKE CALIPER PISTON REMOVER (Part
No. HD-48648) (3) into caliper housing. Install bolt
(2) only enough to hold tool in place.
NOTE
Tool retaining bolt (2) is used only to keep tool from slip-
ping out of the caliper during piston removal, and does
not need to be tight. Do not use a wrench to tighten.
b. If the bleeder valve was removed, install it finger-tight.
c. Apply low pressure compressed air to banjo bolt hole
(1) to remove pistons from caliper bores. Listen for
both pistons to "pop" against the tool.
d. Remove piston remover tool.
4. Wiggle pistons from caliper bores to completely remove.
