put new ebc disc pads in rear caliper yesterday= a doddle Had a go at changing the front!!! disaster, i only have use of one hand, so removed calliper and undid one of the pad support pins ,on the second one my hand slipped and i rounded the allan key head so i cannot remove it? can you buy replacement pins from MZ , also is it possible to drill out the damaged one CHEERS JIM.

you may want to take the good 1 to a MC shop and match up. may be a pretty common pin size.

as far as getting the other 1 out, you should be able to carefully drill off the head of the bolt, then the rest should thread out W/O any problems. you can try an e-z out, but if it breaks, it makes the job 10 times harder.

I have had really good luck welding a bolt that fits into the rounded end to the damaged bolt, then backing out.

also, 1 last one, use an impact style bit driver with the correct size or next size allen socket.

In the past, when a allen type headed bolt has rounded out, I have managed to use a torx bit with a bit of gentle persusion. You have to prceed with care though as it will need some force to get the torx bit to fit and the bolt is useless afterwards.

reverse pitch drill bits are your friend....with a little luck the bit will grab and back the bolt right out for you. I have a set of them that comes with matching sized extractors. As long as the threads arent damaged, you should have no prob getting it out.
