Re: Front brakes lock up
 

For heaven's sake, don't drive it like this. It's hard to diagnose without
knowing what Jeep you have, but it sure sounds like the system is holding
residual pressure in the front lines. It could be the wrong MC if there was
one available for drum fronts. Drum systems hold residual pressure, disks
don't.

Ahhh, that is good to know!

Could be my tenant with the exact same symptoms just got the wrong MC
rather than a 'bad' rebuilt one.

Re: Front brakes lock up
 

You can often make them work by pulling the little spring & piston out of
the port, then screwing the adapter back in. However this isn't something
I'd advise a novice to fool with, just go get the right one installed.

This is a fairly common goof with 76-86 CJs', since the 76 had drum front's
and they'll nearly all interchange on non-power assist systems.
