Welcome back:

That is the most likely issue. The brake assist is provided via the power steering pump. This video will show you how to change it out with instructions below.

Now, here is a link that explains how one is replaced in general:

You will most likely have to remove the old pulley and install it on the new pump. Here is a link that shows in general how that is done:

Let me know if this helps. Also, if you look at pic 16 (last pic) I included an exploded view so you can see how the power steering pump ties in with the brakes. I highlighted the power steering pump and brake master cylinder.

Take care and let me know if you need anything.

My power steering pulley pulled out every time I turned the wheel, it threw my serpentine belt as well I removed the power steering pump and am going to buy a new one, does the new one come with a pulley? If not how do I put it on so it doesn't come off like the last one? And why would the last one have come off like that?

No it does not come with with one. you will have to change it. Is the shaft coming out with it? the power steering shaft could be broken. or the pulley is worn to much.

This video shows you how to remove the pump and pulley

How do I remove the power steering pump? The haynes book says there are only 3 bots to remove but there seem to be more that I can't find.

I've removed the drive belt, the in/out hoses and the plug on the rear of the unit and it just won't come out.

What am I missing?

There is also a rear support bracket, you will have to remove the lower nut to get the pump off

Hydraulic System Bleeding.

1. Fill reservoir to correct level. Allow fluid to settle for no less than 2 minutes. Start engine and run for 30-60 seconds, then turn off. Check fluid level and add fluid (as necessary). Repeat procedure until fluid level in reservoir remains constant.

2. Raise and support vehicle with both front wheels off ground. Start engine. Turn wheels right and left, lightly contacting stops. Check fluid level and add fluid (as necessary).

3. Lower vehicle. Turn wheels right and left, slowly from lock to lock. Turn off engine. Check fluid level and add fluid (as necessary). Lt fluid is foamy, allow vehicle to sit for a few minutes and repeat bleeding procedure.

Okay, yes it could be but before I replace the pump. I would flush the system completely as it may be debris from the fluid.

I would get about two gallons of fluid and flush the system. You need to remove the return lines from the pump and put them in a bucket and run the engine and add the fluid as it is running. Run it until the fluid is clean and no debris.

If that does not resolve it, then yes, replace the pump.

Remove or Disconnect

Place a drain pan below the pump.

1. Hoses. Cap the hoses.
2. Unload the tensioner assembly.
3. Drive belt.
4. Pulley.

Install J 25034-B. Be sure the pilot bolt bottoms in the pump shaft by turning the nut to the top of the pilot bolt.
Hold the pilot bolt.
Turn the nut counterclockwise.

5. Front mounting bolts.
6. Rear mounting nuts from studs.
7. Pump.
