I used Centric calipers and pads for the rear discs. Axle shafts are Yukon. I bedded the hell out of the pads and they are feeling very nice for stopping. Not sure ill switch the valve really.
The pedal has a unique new travel where the first 1/4 is soft, but front brake strong. 2nd 1/4 still fairly soft and starts to get front and rear engaged. 3rd, 4th travel path really start to grab much more, both front and rear, but ends the stop with the front. The pressure difference to travel length is quite different from the drums. Drove a few hours with no ill effect, I feel confidant there isnt air in the line causing this issue. There is a different feel to brakes before starting the vehicle. The pedal travels quite far with ease, once running the booster kicks in significantly.
The parking brake has hella tention on it, immediately on the lever you feel the spring tension. About halfway up with the lever I have the jeep anchored on a drive way in Neutral. I need to look into this more, but I feel like the passenger side is providing far more of the lock up.
still learning the feel of the new set up.
