1991 MU UCS55 rear brakes

[danieljnicholson]

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?

[geeves]

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

[danieljnicholson]

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

[geeves]

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

[turnturn]

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.
