My power steering and power brakes both went at the same time. Fluids are good, belts are good no problems, just stop working at the same time? What do they have in common?

Diesel????

no

Himmmm. Dose the power steering pump operate the power brakes? On diesels they do, that's why I asked. Also on some bid block gas jobs.

Possibly, sems odd they would both go at the same time, pump seems to be fine, plenty of fluid no noise.....

Look on the master cylinder and see if you can see a vacuum canister attached to it. If not then the P.S. and P.B. are related.

Hey I have the same problem right now on my 04 silverado 2500hd my power steering went out and my brakes don't have the same force as normal if I stomp on my brakes it barely stops and when I hit the brake pedals I here that buzzing sound that the power steering makes did you ever fix it I already needed the brakes and nothing

I had a similar problem with my 01 GMC Sierra 2500. When I cranked it up the power steering stopped working. The accelerator stopped working and the brakes barely worked. It was slightly lower on power steering fluid but it was in operational levels. Also the truck would not move of its own accord while in drive or reverse. Electrical or computer failure? ( It was parked on a hill with parking brake engaged)

hey folks, I have a 2002 gmc sierra 2500hd (diesel). Had the same issue with losing brakes and powersteering at the same time. To remedy, I changed the hydroboost, brake master cylinder and power steering pump. None of it worked. Took the truck back to the shop, they said power steering was not moving the fluids around and they suggested getting another p/s pump. Got another rebuild one from shop. Once installed that worked for about 10 blocks and failed. Took it back and they said that they called the dealer and suggested getting a brand new p/s pump (third!). They replaced it and it worked! So long story short, it is usually the p/s problem. Do not get anything AC Delco (although a GM), their rebuilds are junk. Get a brand new p/s and the problem will be solved. Trust me, I spent over 2k trying to remedy the problem. Cheers

I have same problem right now power steering issue the brakes went same time. My truck wont move forward or backwards like brakes are locked on or something. Think maybe computer is doing it. 2004 sierra hd. Will post again when i get to bottom of it.

When I ran out of gas the steering and brakes on my 95 vandura both stopped working. It was terrifying!

this happened to me today in my 2009 mini. I can tell the steering and brakes are not the same. anyone have a similar problem with a mini? anyone know about minis? any help is appreciated.

has anyone ever run into possible high pressure line calapsing. the steering is still dragging and ive already changed the pump, the gear box, and the cooler along with both return lines. steering s still harder than it shoud be but gets better with higher idle

I was low on fluid the power steering started whining so with truck running I hopped out added fluid and the steering was gone when I got back in truck I could see the pump pumping but I have already replaced still nothing brake pedal hard steering wheel won't turn at all

I changed the power steering box on my 1999 gmc serria 2500 then lost steering and brakes.put on a new power steering pump and still the same problem. would i gotten faulty box.i dont think the hvac would have went at the same time.steering and brakes worked perffic before i made changes

A bad speed sensor was the problem when I experienced the same issues
