Abstract：Oil leakage occurred in the dust cover of the piston of rear brake caliper during the structural endurance test of a car type. The brake calipers are not allowed to leak oil during their life cycle. In this paper， the causes of the above failures were analyzed and the causes of piston oil leakage were found out， and through design and process optimization， the problem was improved.

Key words：piston calipers，oil leakage，analytical investigation
