I blew out one but I am stump about how to get the other piston out. I read some posts about getting a rubber seal and closing the other piston opening and blowing it out again. Any good advice ?

Thanks in advance.

Are you talking about brake caliper pistons??

If so, I use a block of wood spacer and blow out both pistons to maximum, remove the wood and give it one more pop covering everything with a towel so you don't die when they pop out!

but only one came out and now all the air is coming out from the hole where the previous piston was ??

You need to use a block large enough to stop the loose one from poping out so you can get the pressure on the tight one!

Put the loose one back in and try clamping it in just enough to seal! It took me a while to get mine the first time!

If I had a willing GF I wouldnt be screwing around rebuilding calipers in the garage.

If you weren't screwing around building calipers in the garage, you'd have a willing girlfriend. Wait a minute...

True, but marry her and you'll be in the garage rebuilding calipers.

But then you would have to sell your Porsche to buy furniture and diapers so you would have no use for your calipers...

Recently did mine using a hand grease gun with the nozzle removed. It screws right into the caliper port. May need a more powerful gun depending on how badly the piston is stuck. I put the already blown out piston loosely back in and clamped it and shot grease into the other side. Piston came right out. Then clean up.
