I was doing a routine brake pad replacement on my Audi 80 when I noticed that the rear brake caliper would not retract properly. The piston seemed to be stuck and would not budge even with a C-clamp. I have checked the brake fluid levels and they are all good. Any ideas on how to fix this issue?
ReplyYou can try using a brake piston reset tool or a large set of pliers to manually turn the piston back into its original position. Be careful not to damage the rubber seal on the piston while doing so.
Make sure to clean the caliper and rotor thoroughly before attempting to reset the piston. Any dirt or debris could be causing the piston to get stuck. Also, check the rubber dust seal around the piston for any signs of wear or damage.
If the caliper and dust seal are in good condition, you may need to bleed the brakes to release any trapped air in the system that could be preventing the piston from retracting properly.
