I have a 2002 mit Spacestar with discs all round and want to change the pads on the rear but cannot depress the piston back into the caliper I do not think it is siezed as it does advance out, I have changed pads on many other vehicles but have never had this problem, it is a lucas girling caliper. Does anyone have any ideas have I missed something? any help would be most appreciated.

Hi Colin
You have to, at the same time screw and push the piston in, I've just changed all pads on the wife's car a 2001 GDI equippe. I used a G cramp and a pair of mole grips, tightening the cramp as I turned the piston with the grips. This I found out 'cos the first side I did the piston came out and I realised what had to be done. With no fluid in the cylinder the piston just screwed in but with fluid in the cylinder you need the G cramp.

I had the same problem. You can buy special tools to do this job but they can be expensive. I did it a similar way to loftyhermes but instead of mole grips, which can score the piston, I used the tool for undoing the screw on an angle grinder to turn the piston. The cutout in the centre of this tool allows the G clamp to be used.

You need a piston winding tool for the back ?
