hello!

I have a 1986 Van30 Diesel 6.2 Liter Diesel van, that was converted into a school bus. (photo below)



So this morning I'm driving home and my power steering and power brakes went out. It was a hard drive home.

I'm unsure what the problem could be but I read online that it's possibly a pump and that on some of these Chevy's the power steering and power brakes share a pump.

Any help would be great, thank you!

 

help!

 

I have a '94 G30 with the 350 gasser engine and it defintiely has a hydraulic brake booster. It's possible yours is the same. The fact that you said you had steering and brake problems at the same time points to that as well. Did the steering go heavy and the brake pedal go hard?

My van has a power steering fluid reservior next to the brake master cylinder and there are hoses going from the reservior to the brake master cylinder. Also, it doesn't have the big round vacuum brake booster like you see on most vehicles.

Does that description fit your van too? If so, you probably have a hydraulic brake booster. If you do, check your P/S fluid level and look for any fluid leaks in the steering rack, brake boster, reservoir and the hoses between.

 

Steering did go heavy and brakes hard.

Went to take a look underneath today and found a broken belt, a rather large one. Might this broken belt be the reason of my steering and brake problems? I think it's my V-belt Fan-Comp-P/S.

 

Have an 1986 g30 that after a water pump repair the brakes/steering are making a loud noise. Both are heavy. PS fluid is full, if not overfilled.

 

These vans use a hydraulic boost rather than vacuum, run off the power steering pump. If the belt is out of position, worn, loose it will make noise and cause loss of assist.
