Check the power steering pump to see if the shaft broke. remove the belt and pull the pulley on the pump, it should not pull out of the pump. If it does you need a new pump

I purchased a 2001 astrovan from my father-in-law who accused of his bad driving because of his age (99 years of age). He said that when he had the two accidents there was no brakes and power stering. The van had only 15,000 miles on it. Six months later I was pulling out of my driveway and I had no brakes or power stering. This problem occurs only when the van is cold. I then looked at the power stering fluid in the resavouir and it was burned black. I then went to autozone and purchased a couple of courts of power stering fluid. I siphoned the black stuff out and refilled it with new. I then turned the stering wheel back and forth to circulate the fluid.. It came up black.. I did this five times and the fluid finally looked good. A friend has two large chevys and had the power stering pump siezed in both of them and the shaft had broken.. My van has 60,000 miles on it and has had no problems. My other friend has a chevy diesel and when I visited him in Mass. he had the same problem. We purged the system and he has no problems. My feeling is that chevy put P.S. fluid that was good for all temperatures and it is no good for moderate climate usage. If you have burnt fluid in the P.S. resivour siphon it and it could save your life.

My brake lines on my 2001 wore a hole in them rubbing against the engine on passengers side. I think this is a manufactures defect.

These 2 items are not connected or related to each others functions. The power steering may stop suddenly if the belt driving the pump from the engine breaks. It may get weaker and start making a noise before it quits if your power steering fluid lines has a leak and gets too low.
The brakes could be a lot of things. 1. have they all stopped working? if so the booster vacuum hose may hove come off, broke or is blocked. 2. If only the front or only the rear is working you may have a broken brake line under the car. 3. The brake master cylinder may have retired. Do you see any fluid under the car or inside any of the wheels?

My chevrolet astro lost power steering and the brakes are hard


Your van sounds like it has hydro-boost.It uses the power steering for brake boost instead of engine vacumme.More than likely you have had a power steering pump failure.

I have a 1995 chevy astro van and the breaks and steering have lost power. The fluid's are full, and I can not detect any broken lines. What could it be?


Your van don't have the regular air (vacum) power brake booster, your has a hydraboost brake booster, which is power by your power steering pump, if power steering pump goes bad you will not have power steering or brakes, brake peddle will feel very hard and will take alot of pressure on the brake peddle to stop your van, more the likely your power steering pump is bad.

Lost power steering and brakes on 96 Astro


Hello altgraph1: My name is Roger and I can help. The power steering and the brakes are directly connected. If the power steering pump fails you will also loose the brake assist. This vehicle does not have a vacuum booster you have a hydro-boost brake system. This unit uses the power steering pressure to assist the stopping of the vehicle. You will need special tools to determine if the power steering pump failed or if the hydro-boost system failed. Most likely the power steering pump failed. How ever to be sure it should be tested first. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

Lost all power steering fluid and brakes


Hi Salmancasmi,
On vehicles with a hydraulic booster you will find that the power steering pump supplies fluid through bot the steering gear box and the hydraulic booster.
Just a visual inspection of the system should point you to the part that failed, most likely a hose. These can be obtained through your local parts store or dealership.
Locate and replace the failed part, refill the reservoir with power steering fluid. With the front of the truck on jack stands, start the truck and turn the steering wheel from full left to full right several times while pumping the brakes. This will remove the air from the system. Recheck for leaks and fluid level and you'll be on your way.
Hope that helps, good luck.

Hard to turn the steering wheel?


on the astro vans they used a hydroboost power brake booster which is driven off the power sterring pump. If you are having brake and steering problems you should check to make sure your belt is still on if it is you probably need a new powersteering pump. You may also check your power sterring pump pulley.if this helps please rate

97 astro brakes and steering out


if this car uses the power steering pump to help with the brakes it is possible that the pump went out or possibly the belt broke as well.

Mine just did same (2001). Have them check the power steering pump--shaft broke in mine. This affects the brakes as well since both power brakes and power steering run off same system in Astros. Broken shaft messed up the booster system.
