Using a C-clamp on integrated parking brake calipers is not suitable for retraction because these calipers employ a dual function: they serve both as standard brake calipers for wheel braking and as parking brake components. The integrated parking brake mechanism typically involves a screw-type adjustment or a separate cable system that directly engages the caliper piston, which often requires a specific retraction method to avoid damaging the caliper's internal components.

When attempting to use a C-clamp on these types of calipers, it may not successfully retract the piston because the mechanism is designed to be adjusted or retracted in a manner that involves rotation or specific tool use (such as a brake caliper tool designed for this purpose). Misuse of the C-clamp can lead to excess pressure being applied improperly, potentially damaging the piston or the related brake components. As such, the correct method involves using appropriate tools that can accommodate the unique operation of integrated parking brake systems to ensure the retraction is done safely and effectively.
