Default ZJ disc HELP!

I just did the ZJ conversion. I can't get the brakes to stiffen up! I've bled a gallon of brake fluid through it and it still gets that brake light in the dash and the pedal is spongey.

WHAT DO I DO!?!?!?!?!?!

does it have something to do with the porportioning valve?????

THere are no leaks.....

Good freaking god...........They were upside down......The crapper of the whole thing is I put a dot of paint on the right one so I'd know it.....I forgot. Then when I was switching them around the jeep fell off the jack. The jackstand I was placing at the time punctured the fuel tank. JB WaterWeld is the sheizer.

well its done now and it rocks! Brakes are awesome.

Glad to hear you got it all worked out man! Only reason I guessed that was because of a similar thread a few weeks back, so you're not alone! haha

did you change out the proportioning valve also? i found i did not have to change the whole valve, just the guts. was much easier to do it that way than to change the whole valve.
