Disc swap?

I swapped to discs finally, but I didn't swap proportioning valves because I wanted to see how it feels.

I can say there is more pedal travel. I bled the brakes with a bottle and had solid fluid when I closed them. Ive always done this method with great success, i just need to know its not air in the line. Is this likely due to the prop valve?

Also how much drag is recommended on the e brake? Currently it's immediate on the handle, but wheels spin 1.5x freely. These don't self adjust do I need to get it right.

Re: Disc swap?

The travel loss is due to the volume the rear calipers consume. As far as the E-brake I have not had any luck with a adjustment that I like and am comfortable with.

Re: Disc swap?

Did you switch your prop valve?

Has anyone tried both and can you say there's a difference?

Re: Disc swap?

I had an 8.8 with disc brakes on my last xj and the brakes felt pretty good. They were better than it ever was with the d44 and drums. I didn't do the prop valve, but I like a little rear brake bias anyway. It's always nice to be able to steer if you need to slide.

Re: Disc swap?

well as RCP says do to the rear calipers, im just trying to get a feel for how these should behave.
I beaded the pads and got a feel for the pedal travel compared to stock. I expected different, but I was quite surprised that the pedal now goes so far in travel. I dont know if its better, but it is different. It would be nice to know the brakes could lock up if I wanted, not happening lol.

If there was air the pedal would just drop to the floor effortlessly right?

Probably the same sound reasoning that concluded the Utah regional chapter should be the part of the Colorado chapter.

So you can't lock up any of your tires (front/rear)? What size tires are you running?

Re: Disc swap?

I'm still running my stock proportioning valve but I moved up to a Durango master cylinder. Understand that I also did WJ fronts so that eats up even more pedal.

99 on 35s, no they arent even close to locking up currently. I had a better shot with drums which I find odd.

Re: Disc swap?

My 8.25 had a lot of end play affecting my pedal travel so I also shimmed it.

BTW, you have a "parking brake" which is meant to keep a "stopped" vehicle from "rolling". What did you do for cables?

you shimmed the c clips or added a washer to the caliper mounting plate?
