Front brakes were noisy on my cb250 so I thought I'd take the pads out and give the caliper a clean to see if that helped. The locator pin holding the pads in requires a hex key to remove it. The hex head on the pin seems stripped. Suspect the pin was lock tighted in and the head rounded off when it was last moved. The pin is recessed about 5mm in the caliper and I'm guessing is about 6mm diameter. Will ezy outs work in this situation? Would it be more cost effective to get it to a workshop? Any other ideas? Thanks in advance.
