Brake Caliper: Testing and Inspection
NOTE: If inspection reveals rubber piston seals are worn or damaged, they should be replaced immediately.
If it is necessary to remove the caliper for installation of new parts, clean all parts in alcohol, wipe dry using lint-free cloths. Using an air hose,
blow out drilled passages and bores. Check dust boots for punctures or tears. If punctures or tears are evident, new boots should be installed upon
reassembly.
Inspect piston bores in both housings for scoring or pitting. Bores that show light scratches or corrosion can usually be cleaned with crocus cloth.
However, bores that have deep scratches or scoring may be honed, provided the diameter of the bore is not increased more than 0.002 inch. If the
bore does not clean up within this specification, a new caliper housing should be installed (black stains on the bore walls are caused by piston seals
and will do no harm).
