brake locked

<< < (2/4) > >>

Yes it could, but problem would have been there long time. Also i would think both frt brakes would be effected. My '59 Elcamino had a problem like that after year after disc brake conversion. Effected both front brakes and i had  to crack line at m/c to relieve pressure. Checked rod adjustment, was ok. It ended up being a hung up m/c piston return, replaced m/c and solved problem.

Problem solved.  Got a pin adjusting tool and tried to set the pin clearance between the booster and M/C but ran out of adjustment.  The pin was just to long.  Ordered and new 8" duel diaphragm booster and M/C combo but went from 1 1/8" bore to a 1" bore.  Set the pin clearance to .020" and everything works fine now.  Better brakes than I had before.  Don't understand why the right was almost locked but the left was a bit more free.  Didn't pull when braking.  Can't stress enough on proper clearance of that pin.  Tool to set it is worth the price on line.

Glad you got it fixed and it is good to know what the problem was.

Nice that things worked out for you, but a little perplexed why one front wheel would lock up........

Yeah buying separate components like that can be a PIA
