a few months ago i had posted a question concerning the bleeding of the front brakes after the removal of the rear proportioning valve and i did the procedure that was posted concerning the opening of one of the front calipers and so on and it seemed to work pretty good but now i had an issue with the rear drum adjuster coming out and after fixing this problem i now am finding that the drivers side caliper is locking up tried to do the same procedure and it backs off but as soon as i close all the bleeders and hit the brakes again it locks up. any ideas? would a front proportioning valve out of a cherokee work better? this is really getting frustrating
