What causes disc caliper to stick?Space and Astronomy
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.
