Symtoms:Shimano M505, front brake pads rattle when peddling hard side to side or hitting rough terrain. They klink a little too when turning the wheel upside down.
Diagnosis: my first diagnosis was a retaining spring that was too loose. I've taken it out, spread it to add more force and same issue.
Diagnosis 2: sticky piston. With the pads off and gently pumping brakes i see one caliper coming out more than the other.
Next step (after doing research) = cleaning the sticky piston, lubricating with mineral oil,
Next step if not fixed = bleeding out a little bit of fluid to create a bigger gap for the rotor.
Am I going in the right direction?
