I have not been able to get either piston to move. Any ideas, without having to buy a complete new cylinder? In advance, thanks!

Just make sure you aren't aiming it at anything breakable. What I do is wrap it in a shop rag to contain the flying parts. | | | | | Joined: Apr 2009 Posts: 14 Apprentice | | Apprentice Joined: Apr 2009 Posts: 14 | I started soaking it this morning. Next I'll try the air. Thanks! | | | | | Joined: Sep 2006 Posts: 841 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 841 | i have had good luck just driving them out. soak them. drive one in a little, clean around it, then drive them out from other side while it in a vise. i use a brass drift, the pistons are like pot metal and can crack but usually don't. | | | | | Joined: Oct 2003 Posts: 445 Shop Shark | | Shop Shark Joined: Oct 2003 Posts: 445 | the wheel cyclinder are usually pitted to bad to rebuild.saftey first .pitch the old ones.NAPA has new one for around $10.ea

Buy new cylinders. They are not that expensive. Your time has to worth something. New ones will save you time.
It's good to be able to go, but it's better to be able to stop. If well working brakes aren't #1, they are darn sure #2.

Old and pitted cylinders aren't worth the hassle. Jim Carters has them if you don't have a NAPA locally.

If you pound on the center of the pistons, they will break quite easily. Mine were pitted but that is not always the case. | | | | | Joined: Apr 2009 Posts: 14 Apprentice | | Apprentice Joined: Apr 2009 Posts: 14 | fifty 3 is correct. New ones are $75.99 ea. at NAPA. I got the stubborn one apart, not pitted just a long time since it had been used. I've rebuilt them all and just have to bleed them now. Thanks for all the help and advice.
