Has any one here rebuilt a master cylinder (for manual brakes). How do you get the piston and spring out. I think mine is siezed up, it has been sitting awhile with no fluid in it from my 68

manual and power master cylinders are the same. They are so stupid cheap, I don't see any reason in rebuilding one personally.

A rebuilt with lifetime warranty is about $15 from autozone. If you're dead set on rebuilding your own, compressed air should do it. Make sure to plug all the other ports though.

There's an internal snap ring where the piston enters the bore. Put the MC in a vise, push the piston down a little, and the snap ring and piston should come out.

I got the snap ring out, it's the rest of the guts that wont come out. I think I'll just get another master cylinder. For the cost and time of rebuilding.

Thanks again guys.
