Why is my new caliper sticking?
The common cause for a brake caliper sticking is with the caliper piston and the brake hose. The piston has a rubber boot on it which lubricates and protects it. But if this rubber is torn, it will cause debris and rust to form inside the caliper which means the piston’s sliding abilities will diminish.
What causes caliper piston not to retract?
If when the piston is pushing out against the seal, it isn’t meeting any resistance from the seal, the seal will not become deformed as it’s supposed to and then won’t retract the caliper piston. This would also be why it’s very easy to push the piston back into the caliper body with a screwdriver.
