Are your rear drums adjusted outward enough. A lot of your pedal travel can be used up just to get the rear pads in contact with the drum. The master cylinder internal rod is staged and the rears have to exert backpressure first before you fronts really start to see the pressure they deserve. Check for your travel on the rears.

your pedal height will come from the rear brakes being adjusted have you done this

adjust up thrrear brakes the should be gragging just a little bit when you turn the wheels by hand the only way to get a big brake difference is to up grade3 to a dual chamber booster from a grand cherokee take the master cly to from the doner truck and th fitting you will need to make new line from the master to prop valve go on line and look up booster up grade for xj cherokee it make a big difference xjs are very under powered in the bracking area soon as you put bigger tirews on them the brakes cant take it

[QUOTE=89whiteXJ;694018]I surprised no one has posted this yet. And a little research would have shown you this.
https://www.cherokeeforum.com/f51/xj...-upgrade-3352/[/QUi knew about this, but i was kinda hoping to be able to fix it with out swapping. if i m gona try bleeding with the knew lines again. 9only bled them once since i put the new ones on) and if that dont fix em ill be searching the j/y's for new booster mc

Bluemax

i have adjusted everything with my dad and they were never perfect the master was even replaced once awhile ago i redid the whole rear brakes i even re routed the rear line ill have 2 post a pic of the line so u can see why i ran it where i did

freegdr

to check the master for internal by pass start the jeep and apply the brakes keep pressure on it with you foot if the pedal creeps down you master is bypassing if not its ok if the booster is bad the grake pedal will be rock hard my brakes were never very good either i did the upgrade and they are much better even with the 38 inch tires

freegdr

one morte thing you are bleeding in the correct order right

Bluemax

pretty sure! srear passenger, then rear driver, then front driver, then front passenger. right!!!

freegdr

thats it like i said my brakes were never even with stock tires good enough that i would trust them to make any kind of quick stop untill the boosyter up grade

freegdr

the booster on the xj is a single diaphram the grand is adouble the grand will put more clamping power to the brakes i have new lines and calipers wheel cyls the booster is the best upgrade i did

freegdr

do booster and master cyl from the grand

Bluemax

any major difference between the double diafram out a grand then an xj

freegdr

go on line and research i think its the arm sticking out of back of booster they changed its not a direct bolt on you have to drill the hole bigger and grind a flat spot in the back for brake light switch to operate and make new lines from master to prop valve just type in search xj booster upgrade in search window

Check front brake calipers. Make sure bleeder screw is on top. If not swap sides. newtjr
