Im after a locost way (free preferably) to wind back the pistons on me VAG rear calipers.

Anyone got any solutions?

screwdriver??

G clamp and a pair of grips.

g clamp

On my Sierra rear calipers, I use the 'spanner' that's used for changing discs on my angle grinder (the two tangs locate within the 'v' of the pistons quite nicely)
Might work on the VAG calipers?

As above pliers and G clamp or peg spanner from grinder. I also have a long bolt with a wing nut on the end so that I can push and turn with a ratchet.

On my Golf i used a kwick clamp and plumbers grips thingy.

I cut up an old socket and use that on a T bar. Works a treat.

Do you mean wind them back as in push the piston back so you can fit new pads? I used a piece of wood and my own force last time

Cube wind back tools are very cheap and work well

The proper wind back tools aren't that expensive.... I think I got a Sealey one for my tintop after faffing around with mole grips / water pump pliers etc etc. Cost me 12 quid IIRC... 10 minutes job done...
