SEIZED PISTONS OUT OF CALIPERS - Help Please
Posted: Mon Mar 12, 2007 12:04 am
Can you help with any ideas please.?
I have callipers off of my MK 1 Pre-Facelift. They were seized but I have managed to get one piston out of each caliper by using a foot pump and blowing air through the brake pipe entry. The other one in each caliper is still well seized. They two that I have out appear to have been slightly rusted in the top of the pots.
I have tried puting my finger over the hole in the empty piston chamber and compressing air, but this is near impossible. I have cleaned up the piston that is out and put it back in the chamber, used a metal bar through the caliper middle with a spacer and again compressed air through my foot pump at up to 80 Psi. The piston all cleaned up works fine but the other one won't budge.
I have now soaked the stuck pistons in WD 40 and left them.
Does anyone have any other ideas I could try?
Many thanks - Gordon
Many thanks
