CLEANING AND INSPECTING
1. Clean all caliper components (except the brake pads)
with DOT 4 brake fluid. Do not wipe dry.
2. Inspect the brake pads for damage and excessive wear.
NOTE: For measuring brake pads, see Periodic
Maintenance/Tune-Up.
3. Inspect the brake caliper housings for scoring in the
piston bores, chipped seal ring grooves, or signs of
corrosion or discoloration.
4. Inspect the piston surface for scoring, discoloration, or
evidence of binding or galling.
5. Inspect the caliper holder for wear or bending.
ASSEMBLING/INSTALLING
1. Install new seals into the brake caliper housing and
apply a liberal amount of DOT 4 brake fluid to the
cylinder bore of the housing, seals, and brake piston.
! WARNING
Make sure to hold the towel firmly in place or the piston
could be ejected from the housing causing injury.
CAUTION
Make sure the seals are properly in place and did not
twist or roll during installation.
