(8) Using a soft tool, such as a plastic trim stick,
work piston seal out of its groove in caliper piston
bore (Fig. 94). Discard old seal. Do not use a screw
driver or other metal tool for this operation,
because of the possibility of scratching piston
bore or burring edges of seal groove.
(9) Clean all parts using alcohol or a suitable sol-
vent and wipe dry using only a lint free cloth. No
lint residue can remain in caliper bore. Clean out all
drilled passages and bores. Whenever a caliper
has been disassembled, a new boot and seal
must be installed at assembly.
(10) Inspect the piston bore for scoring or pitting.
Bores that show light scratches or corrosion can usu-
ally be cleared of the light scratches or corrosion
using crocus cloth. Bores that have deep scratches or
scoring should be honed. Use Caliper Hone, Special
Tool C-4095, or equivalent providing the diameter of
the bore is not increased more than 0.0254 mm
(0.001 inch) (Fig. 95).
