Van makes sound when brakes appled and turning Is

the system lacks fluid or there is an internal leak in your system. Look for wet wheel cylinders, leakage on the lines, etc. check for low fluid levels, on your brake system and in your power steering fluid container.

more than likely it is just low on power steering fluid. system might have air in it now. so after fill power steering unit to proper level driver the car and check fluid level again. and add more if needed . I believe car should have motor running for when checking fluid, same as transmission.

Hello! There are power steering fluid in/out hoses but no vacuum lines...It sounds as if the pump needs to be bled of air or the belt is loose...Belt should move about 1/2 to 3/4"...Bleeding is as follows...

ImportantPower steering fluid level must be maintained throughout bleed procedure.

1. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.
ImportantWith hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.

2. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
2.1. Start the engine.2.2. Firmly apply the brake pedal 10-15 times.2.3. Turn the engine OFF.
3. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle in General Information.
4. Key on engine OFF, turn the steering wheel from stop to stop 12 times.
Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.

5. Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid .
6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
7. Verify the fluid level. Repeat the bleed procedure if necessary.

Check for a Front caliper locking and not releasing or for poor vacuum on the master cylinder. This could also be an issue with the Brake Cylinder being low on Fluid so check your fluid level. You also need to check your rack and Pinion steering or Power steering control to make sure you don't have binding.

Yes, your brakes are boosted by the power steering pump rather than by vacuum. I don't think it's air in the system. More likely your pump has failed, but you can try bleeding the pump. Here is a procedure from autozone.com:

Observe the following:
Use clean, new power steering fluid type only Hoses touching the frame, body or engine may cause system noise. Verify that the hoses do not touch any other part of the vehicle. Loose connections may not leak, but could allow air into the steering system. Verify that all hose connections are tight.


NOTE Power steering fluid level must be maintained throughout bleed procedure.

   NOTE With hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF . This will discharge the hydro-boost accumulator.

4. With key in the ON position and the engine OFF , turn the steering wheel from stop to stop 12 times. Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
5. Verify power steering fluid level per operating specification.
6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).

It's not the transmission, because you wouldn't see the space that the transmission fluid fills, and it's doubtful that it's the brake fluid, the brakes will act up all the time (stop lights, etc) if that were the case, so it must be the powersteering fluid. If your car is sort of a pain to steer around corners, the slower you go, the harder it is to move the wheel to turn, and you hear a sort of whiney noise when you get into a deep turn, or are turning slowly, that would for sure be powersteering.

HI. You power steering fluid level may be low at this point, a quick inspection of the fluid level, will be in order, if possible. Once you have verified that the fluid level is sufficient, move on to the actual power steering belt and unit. Make sure the belt is tight, and rotating the pulley. If the fluid level is low, be sure to fill to specifications.

Now, If the pulley and belt are rotating without a wobble, and the fluid level is sufficient, this will lead to a failed pump. The pump should be replaced in this case. Make sure you exhaust all inspections points mentioned before replacing the pump.

CHECK LIST

1. Check the power steering pump hoses for leaks
2. Check the power steering pump pulley for lose fit or wobble during rotation,
3. Check the power steering reservoir for proper level(add if needed)
4. Check the power steering drive belt for the proper tension.

Make sure u check the level with the car running. If the fluid level is still good and still have a steering wine. you have a fluid restriction. This would involve replacing the power steering resivior. The filter screen gets clogged and causes a restriction hope this helps.

Check your hoses around your power steering resevoir, you might have a pin hole leake in one of the hoses. Make sure to keep an eye on the fluid level. As long as you keep fluid in it you won't burn out the pump.

Check your wheel bearing. Make sure all is tight and ok
