I was driving back to Chicago from texas when I lost both my brakes and power steering, I checked the Power Steering Fluid and it was full. I managed the 1200 journey very carefully but need to fix the problem...........any ideas ??

 

I hope not but, it could be you power steering pump isn't pumping. The brake booster operates off p/s pump pressure.

 

there could be internal problems inside the vacuum pump welcome to diesel bombers and hope you get your problem resolved

 

most of these trucks had a hydraboost system where the brakes are assisted by the pressure of the power steering fluid. the boosters themselves are very prone to going bad on chevrolets but i have never heard of one going bad on a dodge. a possibility though!

 

mine almost did the same thing and i changed the pump and the hoses and it seemed to fix the problem

 

Yep. Need a new pump.

 

Thanks for all the answers, I will pull it off tomorrow and check.

 

Updates??

 

Please update.
