Volvo has issued a recall on the brake vacuum pump which can be viewed at www.automallusa.net/2000/volvo/s40/recalls.html that involves water invading the pump, which would cause noise and braking problems.

Hope this helps, and good luck.

    Yeah, I looked into that before I posted my suggestion, and the recall is for the mechanical pump including your vehicle which does fall within the recall's range of years and models. Not being familiar with the type of pump design Volvo used, the only other possibility I might think of for a noisy vacuum pump would possibly be low internal lubricant level, if one is used in that pump. Check out the recall, if you haven't already.

Power steering pump is making a lot of noise, especially in the morning when it's cold outside.


It is the pump itself making the noise, or is it the drive belt slipping on the pulley? Sometimes the belt just need tightened, or replaced if it is glazed.

How do you know that a brake booster is bad?


Booster problems are rare but they do go bad sometimes.
A bad booster generally causes the brake pedal to feel hard to push down, and a lot of pressure on the brake pedal is required to make the car stop.
Rarely, a vacuum brake booster will develop a vacuum leak, which can cause engine performance problems, hissing or whistling noise, as well as requiring increased pressure on the brake pedal to stop.

The first test:
With the vehicle parked, turned OFF, and the parking brake set, pump the brake pedal 5 to 6 times. If the pedal gets harder to push after several times, your booster is probably good.

The second test (To make sure):
After the test above, without making any changes, press and hold the brake pedal with light to moderate pressure.
Now with your foot still on the brake pedal, start the vehicle.
If the booster is good, you will feel the pedal go down when the engine starts.

Hope this helps!

Why is it so hard to apply brake pedal?


_______power brake booster, check vacuum to booster and the check valve for brake booster. primary symtom is high hard pedal that requires greater then normal pedal pressure to stop car. testing booster= pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on brake pedal. you should be able to feel the pedal fade away a bit, and then become firm. But not hard. if you feel nothing at the pedal when engine starts. Brake booster is not working. Good-day! make sure vacuum is going to booster with engine running. it may just be a bad vacuum line or check valve.

Died while driving


The issue is the injector pump, it is in the plenum for the intake manifold, the clunk noise is a cv or universal joint.

Could either be a bad vacuum line or the TSB for the IWE solenoid.

If you have the truck running in park ( parking brake, chock wheels, necessary safety precautions ) check the vacuum on the front right IWE vacuum line. there are 2 vacuum hoses on there, 1 is the vac, the other is the vent, which routes up into the engine compartment, and is not hooked to anything.

Usually if it is the TSB, both sides will be making the grinding noise, as they are a common IWE solenoid

TSB : http://my.voyager.net/~sscully/file_tsb06_08_15.pdf

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vacuum is removed the spring engages the IWE.

What are the signs of the brake booster is going


Generally there will be a hissing noise on brake application or brake will become rock hard and will take a lot of force to stop the car. If brake is hard, check first that the booster is getting and holding vacuum.

Vw t4 '03 tapping noise


Hi,

Next time it's tapping at idle, press the brake pedal hard several times. If it stops tapping then gradually returns then it is a noisy vacuum pump.

It can go on like that or years (if you can put up with the tapping that is!) if you start to loose servo assistance while manovering then it's time to change the pump.

Hope that helps.

When you press on your brake pedal does it make any "squishy noises" "snorts" "mouse squeeky noises" "vacuum noise". Your brake booster (60$ or so used) may need replacing. The vacuum pump from your booster takes a lot of power from your engine if not working properly. When the the brake booster is not working properly, say having a torn diaphragm, your car will idle very poorly; when you press on the brake you may even get high revs; and because there is too much energy loss, your engine will sputter and shut off when you leave it idling.

Look into it. It's an easy fix. Remember to move your brake pipes gentlyyyyy though.

I am looking for a wiring diagram so I can install a remote car starter. If you have anything for me let me know.
