Brake Caliper: Testing and Inspection
1. Clean all metal parts with isopropyl alcohol. Clean out and dry the grooves and passageways with compressed air. Make sure caliper bore and
component parts are thoroughly clean.
2. Wipe off the disc brake caliper (2B 120) and inspect for cracks or other damage. While disassembled, inspect the caliper bore and caliper piston
for pitting rust or other damage. Inspect the seal groove for nicks or other damage caused by using a metal tool to remove the piston seal. Replace
as necessary. Do not attempt to hone a damaged caliper bore.
