Hello all, I have a '71 500L. I am doing a partial brake job and can not get the brakes to pump up. I decided to try and replace the master cylinder, but the brake lines that go into it are frozen??? I can get the thing off. Any ideas
 
keep squirting WD40 into the joints for several days aand try again. If still stuck you may have to try air hammering them to shake then up. Alternatively you could try gentle blow torch heat ensuring you shield the rest of the stuff.

To air hammer them you will need access to an air chisel gun and small mallet head. A local body shop will have the kit.
