i have the same problem with my 97 GMC Jimmy. I removed the booster to find a hole in the inner diaphragm. Replaceing the whole brake booster should fix you up
you need a new break booster!!! the air you hear coming from the break booster!!! makes the rpm dope pressure!! too the engine power!!!! once thats fix!!! then when you press on you breaks the rpm will be normal!!! no air sound from the break booster!!! no drop of pressure too the engine!!! then your done!!! back on theroad again!!! god bless!!!one!!
i just had the same exact problem to come to find out it is the brake booster i learned the hard way and bought a master cylinder for it but oh well with a truck with almost 250,000 miles on it i guess its a good idea to replace it too lol good video
Mines doing the same EXACT THING!!! yes this video was posted a year ago but im glad it was cause im almost POSITIVE with reading up on this, and watching your vid im having the same problem. I push brake and I hear nothing but " SHHHHHHH " and engine dies, i tow a jetski and when backing it in, it stalls almost every time in the water..
when i press on my pedal it makes a loud hissing sound coming from the rear drum brake area and green fluid drips from the rear of the car,, HELP PLEASE!
it needs to be replaced, also replace the check valve if one is not supplyed with the new one, boosters are not expencive but can be a bitch to replace there only about $50-60
I am having this same exact problem with my 95 olds cutlass I am almost 100 percent sure it is the brake booster. I have already bought a new one now I am just working at it. I hope you fixed yours by now. Considering you were having this problem a few months back you have me wondering whether or not you took care of it. Hopefully it's not too hard of a job as what I am thinking it is going to be.
dunno if you've fixed this or not, but just in case... the diaphram in your brake booster has ruptured somewhere. The air you hear is air leaking past the rupture when you press the pedal. The engine RPM change is from the vaccum leak caused by the rupture. Basicly, your engine is sucking air in from around that rod on your brake pedal. Only fix is to replace the booster. good luck!
same thing on my 98 blazer cant get to the bolts on mine with standard 15mm deep-well

ok, i think your car has air in the brake lines, but if the brake booster is making like air noise, i recomend you to change it
