WARNING
Do not use more than 25 PSI(1.72 Bars) to remove
the piston. If the piston does not come out using 25
PSI then the piston is seized and the caliper should
be replaced.
5: Using compressed air, slowly increase pressure
in the caliper until the piston is pushed out.
6: Remove the wood block and piston.
7: Remove the o-ring.
8: Inspect the caliper bore for any signs of damage
or wear. If there are any signs of damage or wear
then the caliper should be replaced.

wear. If there are any signs of damage or wear
then the piston should be replaced.
10: Lubricate a new o-ring with DOT 3 brake fluid and
install it into the caliper bore.
11: Lubricate the piston with DOT 3 brake fluid and
CAREFULLY place the piston into the bore and
press in using hand pressure only. Excessive or
uneven force may damage the piston sides and
result in a brake fluid leak.
