In the middle of changing rear discs and pads. Calliper has already been taken off and the old pads removed.

Can someone please tell me an easy way of undoing the calliper mounting bolts so that I can take the discs off. There seems to be no space to move the rachet to undo the bolts.

Also the piston is refusing to rewind. Do I have to apply a lot of force to rewind (don't want to knacker anything). By the way, this is the tool I am using http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWNX:IT

Thanks.

P.S. I posted this earlier on today without a reply.
