Archived hydroboost and steering - did a search

[DDeFreece]

Problem solved - lines were backwards



Did a search but didn't see anything that matched what is going on. I need to drive this thing to work tomorrow. I am in a bind. AND, the wife is not happy as it's been under the carport for 2 months.



I just put a Cummins in my truck and it already had the pump on it. I have never dealt with hydroboost before.



I installed new lines, new hydroboost, and new master cylinder.



It turns just perfect until I hit the brake pedal then it gets jerky. I know I need to bleed the brakes some more and the pedal goes further than it normally will. But I didn't think that would affect this.



What do I need to check?



Please help. Thanks.

Could you fill in your signature with your truck info? We need info on what the truck is and what you've done so as to help you. Does it turn smoothly if you increase rpm's? Have you tried to bleed the power steering system again?

I added the truck.



1978 Chevy Bonanza Blazer (great shape I might add - New Mexico truck)

Rebuilt Cummins 4BT

Chevy NV4500 mated to an NP465 Bellhousing w/o adapter

NP205 32 spline mated to the NV4500 w/o adapter

14 Bolt FF Rear with Eldorado disc brakes

Dana 60 front with d60 calipers



Everything above but the rear was just put in. Cranked it for the first time Friday. I have about 20 minutes run time on the motor. Before this the PS pump sat up on the engine full of oil for about 2 years.



New hydroboost, new master cyl, old steering box but was having no problems with it.



I just bled the brakes again and got no air out. Going out to crank it up.



Can't think of anything else.



Thanks
