I have one caliper that the adjusting screw does not work. after about a half turn you feel it pop and then nothing. where can I source repair parts?
does anyone have a part number for the caliper?
whats the trick to get the rear rotors off?

Rear rotors are held in place by the wheel nuts and one 10mm bolt in the face. They can be a tight fit so pulling forwards on on side while giving it a light tap with a mallet on the other side may be nessecsary

that is what I thought but I don't see any retaining screw on the rotor, only a very small hole as seen in the pic

that hole should have a 10mm bolt in it. Sometimes it has to be removed to fit after market wheels. It isnt needed as the wheel nuts also hold it

I'm pretty sure that mine have no extra bolts holding them on. Just the wheel/nuts.
The internal workings of the caliper are not listed as parts so suspect that you would have trouble getting them, or even the complete caliper.
