Air hissing noise from brake pedal 2002 ml 320 mercedes

Mercedes MLs 98-05 have an issue with Brake Booster seal. I had numerous MLs with that issue. As long as you have good functioning brakes and your only concern is the hissing from under the pedal, then you have no issue with the actual booster.

If you go with any unsuspecting mechanic, they will recommend you to replace Booster and it will set you back about $1000. The solution in replacing a simple seal that goes bad and starts leaking air back into the cabin under the dash, thus causing the hiss..

Why would I have plenty of vacuum at my brake booster line? But none in the smaller lines on my 1977 Mercedes 300D like the one going to my shut off valve. Rebuilt vacuum pump and the engine only has

You still have a leak somewhere or it is plugged up. The brake booster is not the culprit. Find the vacuum canister and trace from there checking each line.

In less than 6 mothns, my mercedes 2006 ML 350 has been giving me a brake problem. I get too much play when I push the brakes, meaning I literally have to pound my foot all the way down to get it to stop....

If you mean that the brakes are hard to push but the pedal still only travels its normal distance then:
This is either a brake assist valve. A brake booster problem, or the vacuum line that feeds the brake booster.

If you mean it goes way to the floor before it stops you then you have a bad master cylinder or some air in a line.

I'll assume you don't have any warning lights on.

How to test my brake booster to find out if it is working properly or not. Thanks

Find a way to pressurize the booster. At the suction port of the booster you would have to fabricate a tire valve and maybe install an air gauge to see if air is leaking out. Remember there is a rubber bladder inside the booster.
If air is leaking around the rubber diaphram then the brake booster will not work. Did you check the hose and valve going to the brake booster? If you have a vacuum leak, then the booster will not work.
Was your master cylinder leaking inside the brake booster? When brake fluid leaks inside the booster the brake fluid will destroy the rubber diaphram. hope help.

E55 amg not starting

sounds like a major vacuum leak. I would check the hose going to the brake booster(there is a check valve that can fail in that hose as well).

Engine switches off whenever brake is applied.

You have a vacuum leak if it is actually caused by the depression of the brake pedal. check your booster hose and check valve-most likley causes-chack brake booster next. it is possible the idle speed has a problem and it is happening when the throttle is closed and it seems like it is related to the brakes but ir could be engine management-hopefully i have been helpful
