Thanks Bruce - your post helped me out qutie a bit earlier I was also having a hard time figuring out if it was 1/4 or 3/16..
I did this earlier today on my friends lift, I'm not a beginner but I'm not a fast expirenced mechanic either. I was able to do the RF, Both Master Lines - And the line running back to the splitter - it took me nearly 5 hours including a trip to the auto store. I messed a couple things up - and my biggest fudge was definitely on the last two lines of the night Is switched one of the lines going into the ABS module from the bottom to the top (so 5/16th fitting into the 1/4th fittings hole) - I didn't stripped the threads out - but I can't put the 1/4 fitting back in there anymore.. I was flaring the right front line and the rear master line at the same time and got the fittings mixed up - very dissapointed inmyself.
I'm going to go to the store tomorrow and see if I can get another 5/16 fitting and just run that in the front right's spot since I already reamed it out.. hoping it will seal up.. don't want to have to go to the JY and pull an abs module.
Wish me luck.
