Purestock3 Posted June 8, 2006 Report Share Posted June 8, 2006 I drive a 2000 1 ton chevy w/ABS Yesterday, the power steering sprung a big leak. Made lots of noise of course, but I'm confused about something. At the same time.....everytime I hit the brakes the noise got worse. Within a few minutes I had NO front brake. I added p/s fluid and the noise went away for a few minutes...then leaked out and it came back. Today the noise is gone....no power steering/no front brake. I'm pretty sure the P/S pump is burnt now, so I'm fixing the leak and maybe replacing the pump today. But what the heck happened to the Brakes!?!?!?! Am I missing something??

matt5858 Posted June 9, 2006 Report Share Posted June 9, 2006 Check your hydro booster behind your master cylinder. That might be your problem. The hydro booster works off of your P/S pump. It gives you power brakes. No p/s fluid = No power brakes. Hope this helps. Link to comment Share on other sites More sharing options...
1-Crew Posted June 10, 2006 Report Share Posted June 10, 2006 Not an unusual system on 1 ton or larger vehicles, since the vacuum may be "iffy" on such due to heavy loads, some form of hydraulic assist is used. On a '76 1-ton GMC van (class C motorhome) I had, it was driven off engine oil. I would not be surprised if yours wasn't driven off the power steering pump..

Purestock3 Posted June 10, 2006 Author Report Share Posted June 10, 2006 Well I feel pretty dumb...... Next time I have a problem I'll look first then ask. There is a line coming from the steering box straight to the power brakes.......right out in the open. Link to comment Share on other sites More sharing options...
Purestock3 Posted June 13, 2006 Author Report Share Posted June 13, 2006 Simple enough.... Wish I wouldn't have had to drive it for a week before I fixed it. Was just a leak, ended up having to replace the pump too. Link to comment Share on other sites More sharing options...
