Just been changing the brake discs on the car - having spend absolutely ages (2hrs+
) trying to do the first one, then trying to get the brake piston back in, I finally gave up and went to Halfords.
Bought a pistion ram, pushes the piston back in by driving a bolt against the piston head which is counteracted by the caliper itself. I spent about 30 minutes using all sorts of implements (ranging from hammer handles, to an 18" tommy bar, finishing with a 6' broom handle) before admitting defeat and going and buying the ram. Did the second disk in about 35 minutes
from taking the wheel off to putting the wheel back on.
Unfortunately
I was only doing this while the battery on the bike recharged, so the other two discs will have to wait until later in the week!

It definitely just pushed in didn't it and wasn't a screw in type piston was it? I only ask as I have a new vectra and went to do the same. Couldn't push it back so before I forced it I asked on the vectra forum and turns out they screw back. If i'd forced them back I'd have damaged the threads they screw in on. In the end, I got my m8 to do them at his garage.

Um, think you might be right Bigun, the piston was rotating when I tightened the piston ram, so odds are it was screwing in rather than just pushing in.
Where's the "I feel so stupid" smiley? Ahh yes, here it is
Still think the tool is great, mind
deffo wouldn't have done it without

I haven't touched a car caliper since - oh, think it must have been the Datsun Cherry which was scrapped, oh about 22 years ago when the bottom dropped out of it!

rear callipers wind back as you apply pressure to the piston, but you must wind the piston back to the pads or you wont have a hand brake.

if the hand brake is part of the caliper then no,but on some cars the hand brake as it's own shoes and is inside the disk, mostly on vauxhalls.
