I am tearing my hair out getting my brakes to work correctly. I have changed everything (pistons, shoes...) and my brakes squeal heavily (metallic noise) when applying a light foot on pedal. They shudder a lot too. I have to push the pedal in and brake hard to stop the noise. only issue is that I'm braking way too hard !! I dismantled everything and someone told me to reverse the anchor pin to better center the shoes. Results are worse !! I also tried to set the anchor pin correctly. Followed the manual but I am not sure the pin centers itself very easily. Plus there is not a lot of play. Any had experience with this ? Which way does the anchor pin go (see picture) ? Why do pads shudder ? (they seem to grab and release... I assume the pads are not correctly set ? I followed the manual though..). I will take anyone's advice !!!
