Inspection

When disassembled...

Remove wheels and inspect brake disc, caliper and linings. The wheel bearings should be inspected at this time and repacked if necessary. Do not get any grease on the linings.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

Should it become necessary to remove the caliper when installing new parts, clean all parts in alcohol, then wipe dry using lint-free cloths. Using an air hose, blow out drilled passages and bores. Inspect dust boots for punctures or tears. If punctures or tears are evident, install new boots during assembly.

The pedal effort and pedal feel during normal braking are similar to a conventional power brake system.
