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!
