Ive got a 75 fj55. I am looking into getting into the disc brake conversion. SOR is near 20 mins. away. Anybody used their conversion? I have taken the front apart and put back together to the burfield, but I am no mechanic. My last project I bled only a little. Amongst the million questions, I get a little intimidate when people talk about porportioning valves. Do I need to get a different master cylinder? I have heard something about simply shortening the plunger and using the one I have.
