I have replaced Propostioning valve, all brake lines, new pads and rotors, new shoes and drums, new master cylinder.
The only thing i have not done was replace brake booster or brake pedal assembly

My pedal just goes to the floor still, i have bench bled the MC and bled the brakes about 30 times and finally got a solid stream of fluid on all 4 corners, I took to menieke and they looked at it and they adjusted the push rod into the MC and called it good

I can stop ok on the street but i tested on some hills and obsticales and the brakes still wont keep me from sliding down or off the rocks
couple options i am looking at for additional "safety" is connect the E brake back up, or do the AW4 Torque Converter Lock Up mod for going down hills
plz help with any advice, its getting frustrating buying and replacing stuff and still has the same outcome

 

The tq converter mod used for braking is VERY hard on the converter. Good upgrades ZJ rear disc, 95+ dual diaphragm booster, WJ knuckles and rotors to name a few.

 

The easiest way to gain better braking do a zj rear disc converison easy to do i did to my truck and stops 35s like no tomorrow best upgrade to date

 

The pedal should not go to the floor, something is wrong. If you are sure you got it blead...you did have help? If it's bled, the rears are adjusted tight? That would do that, rears not tight...then maybe a bad master cylinder. Idk...bled with the rears adjusted, it should be up solid is my thinking.

Does the E-brake need to be hooked up to hold the rear shoes properly? Maybe someone can chime in there...seems that goodie there on the wacchyamacallit might matter.

 

Do you have good vac pressure comming off of the motor? You can replace everything brake related but if you motor is tired you won't have enough pressure for the booster
