I replaced my pads on my 1995 Magnum today. Thinking this was as simple as doing car brakes…I pulled the retaining hex screw…disconnected the mounting bracket….with the master cylinder cap off I used a c clamp to push the piston back in and changed the pads….did the same on the other side.
When I pumped the handle afterwards the pistons became rock hard and wont release now? I never broke the brake lines so I wouldn’t think they would need bleeding? Any ideas whats going on? I did notice a little round filter like disc in the master cylinder not connected to anything?
