I just finished converting my 74 FJ40 to front and rear disc brakes. I purchased an AISIN four wheel disc brake master from JT Outfitters. The master cylinder bolts up fine but as you put it on there is pressure being applied. I'ver done several searches and tried some tips such as tightening the adjuster all the way in. By this I am referring to the small rod that goes into the booster on one end and into the master cylinder on the other end. I have also tried to adjust the brake position from the inside. I have the thin booster also. I still need about 1/4" or so to take the pressure off. Can the adjusting rod that goes into the booster/master cylinder be shortened? I have also read about shortening the other brake rod. Any suggestions?
