1988 Jeep Wagoneer Limited 6 Cyl 4.0L

Brakes

Shouldnt the pedal at least pump up even if I havnt bled the system?

I could hear an air leak when the brake pedal was pushed and the pedal was low so I replaced the booster and master cyl. Now the pedal goes to the floor and wont even pump up with the moter on or off.

Absolutely not, you have to get the air out. I have a feeling your cause was not the master.

First of all did you bench bleed the master cylinder be for you installed it ? Thats where you put it in a vise .fill the resivore attach the hoses to the line outlets and put the hoses in the resivore held under the fluid and then using a screw driver and pump the piston till all the air is out of the master cylinder before mounting.
