Have swapped over disc brakes from B310 to my 1200 ute, brakes locked on after a couple of days due to arm connecting to brake pedal being to long (using 1200 master cylinder 11/16th). Swapped over arm, brakes better. Now, theres a rubbing sound coming from front wheels on every revolution, took caliper off and found that anti-rattle shim was hitting. Adjusted that, put it together, drove off fine for 2 minutes. Noise still there and getting louder. Disappears when slight brake is used. Any idea's?? really starting to annoy me...
