Check your power steering fluid level. The power brakes are hydraulic assist and get hydraulic pressure from the power steering pump. If the fluid level is good you may have a bad pump. If the fluid level is low fill it up and find the leak ASAP.

We'll this is unbelieveable... I found that the power steering shaft in the pump, Broke.
I purchased a used pump assembly and had it installed AND the pump I just had installed worked for One Day and the shaft on the steering pump Broke AGAIN !!
Has anyone else experienced This?

Also what is the solenoid/swich that is mounted on the power steering pump assembly. Could the problem be this switch? OR.. In the steering Box?
PLEASE HELP HELP !!!!! ASAP !!

I have heard of the pump shafts breaking. My assumption is that it is probably a casting defect and that the pumps of similar vintage are therefore all prone to the same failure. I would assume that it is a pump problem and not go looking to make it more complicated. Either get another used one and cross your fingers or "step up to the pump" and get a remanufactured or new unit with a warranty. Sorry for the bad pun, just couldn't help myself.

Problems with power steering and power brakes. Took it to a Chevy dealership and they said it might be a power steering booster. They said they would replace it for $1000 but woud not guarantee that it would fix the problem.$1000 for a guess? Chevy needs some good mechanics.

hey rick i was just wondering if that when your power steering pump snapped did it spray power steering fluid all over the engine bay?

1997 chevy astro van.If the power steering and brakes go out the problem is either you need to add power steering fluid or your have a bad power steering pump. Just the power steering pump should cost around $65 at pep boys and $75 at kragen remanufactured. And the labor should cost around $140-$220, so all together it should be less than $300

Can't fault my astro. First problem in 315,000. It is the pump on mine. Hilarious actually, I drove it for servicing and no problems. The insulation in the wheelwell was loose and that made a noise, so they put a new snap on it. The mechanic took it around the block to ensure no more noises, and the steering and brakes when when he was driving it. Will get fixed Monday.

Thanks for your wise information. This just happened to our van last night. Very informative!

I have a 1994 Chevy Astro Van - same thing- no power brakes or power steering. I replaced the pump (lots of fun) but it still did not solve the problem. Is it possible the pump I put on was bad too(I got it used from an auto salvage place)? Is there a way to test the pump out of the vehicle? Is there some other check valve or device that would cause loss of hydraulic pressure? Thanks for anyone who can help me with this!!!

Just read all these comments...if your brakes and power steering get stiff, it is your power steering pump...if your brakes only get stiff, it is your brake booster...the power steering pump is located on the right side on bottom pulley as you are looking at engine from front grill...if you have A/C it is not fun...and yes it is common to buy used or reman bad pumps...and it is common for the shafts to break...and unless you own, can borrow from friend or parts store, you will need to purchase a power steering pump pulley puller and installer...if you are lucky enough to get the pulley off the old shaft you should never hammer or strike it onto the new one, you take a risk of breaking the new shaft...good luck

Quite a club we have here, I am repairing an Assto. Then sure enough after going through the difficulty of replacing the pump while bleeding the air out of the lines on the second hard right turn of the steering wheel the shaft to the pulley sheared again. Wow what a let down and $45 down the drain too. Called the local Chevy dealer and fortunately the shop foreman has had two such miladies in the last decade. Jay said the first one was a really crushed fluid line on the pressure side, not my problem after a through inspection. Secondly some servo valve can be replaced in the steering gear box but with the wear of 150,000 miles or more it will not last if it works at all. Best to flush out all lines connected to the pump and put a new or rebuilt or used in good condition steering gear box in the solve the problem.
So that's what I know about it and I hope it helps some one out there like I needed help to repair the one I am working on.
