I have a 96 Dakota that i took to a shop. When i dropped it off to have the bushings changed, the brakes worked just fine. After having bled the system the brake pressure works while the vehicle is off but as soon as it's turned on the pressure goes away completely. There are no leaks in the system and the pwr booster is good too! Does anyone have any idea of what this could be? HELP!

 

Welcome to DF

I will move you post to the 1st Gen Dakota section.

 

Sounds like you got air in the lines. Re-bleed it. All 4!!! Rear Right then left, Front Right, then left. Bleed for a long time to make sure you get all dirty fluid and all air.

 

This, and as old as the vehicle is you may need to replace the lines. I had to on mine when I had my brakes replaced last inspection. They were just so old that they had all sorts of crap in them. Didn't cost much and breaking is way better now.
