This is a really good video! Explains the issue/symptoms perfectly! My 1990 Honda Civic Hatchback DX has a bad break booster and you described it to a T in this video! Great Job!!

6th symptom at idle in park when you apply the break the engine rpm goes up because booster is torn internally the hissing sound may or not be present!

Replacing it immediately, seeing if it that fixes it

@funv3188 2 месяца назад

We have same symptoms. When braking a car makes like fluctuating noice and some whistle while accelerating. We thought its from turbo intake hoses, etc, or the worn gears, calipers,shaft bearings, etc. Pedal looks stiff also rps increase a bit as you say. Will do a smoke test I gues and inspect cylynder. But I think this will be it 😂 I was thinking could that be reason if two persons were bleeding brakes and and one hit hard on brakes, another purged on screw, tighten, release.I think that could be a reason for membrane damage. As I remeber a termitaror was bleading the brakes 😂

So many damn videos watched and finally! I find it, I switched the master cylinder since it was the cheaper option to start with. When i press the brake it goes to the floor and hisses the entire time. So many videos talking about the stiff brake pedal but never the hissing noise. Thank you!

Hello. I have a skoda superb 2016 1.8 tsi. My problem is my brake sometimes remains in boost mode even after I release the pedal. The pedal comes back but the master sticks. I noticed that it releases slowly with a hissing sound after i release the pedal. My car has 80000kms on the odo and never gave me such trouble until lately. The brakes were bled 15000kms ago. The rear pads were changed 3000kms ago.

Can a failed brake booster cause a stutter when I hit the throttle in park only on a cold start? I have all brake lights coming on and off in my car and the stutter stops once I start driving. I hear a hissing under the steering wheel after I shut the car off. It's a 2010 dodge charger 3.5l

Keep following your heart. Critical thinking is needed to understand mechanical parts and how they fail. I recently took apart a vacuum pump, which ran but vacuum was constant but intermittently pushing air. There was a flimsy oring that was allowing air to pass. Sealed w rtv and it blew like I’d want my next girlfriend to blow or suck.

We have a VW Touran Tdi 2011 model (automatic). We have a whooshing sound when pressing the brake, always air in the lines, the brake pedal goes down far before the brakes bite and braking distance is too long (also weak) however after bleeding its always better, somehow air is coming into the system but we dont know from where, we think its the booster as we have replaced the Master Cylinder already. We have some residue on the inside of the booster under the dash/pedal, could that mean a faulty seal? We dont have a rock hard pedal but still think its a leak when you press the pedal. Any ideas?

I've similar symptoms, ive changed the BMC but it didn't work. Sometimes my break works sometimes not. I also hear a noise like air pump when pressing the paddle. My left back wheel is not pulling break oil. Maybe some air trapped inside? Oil doesn't come from one abs valve. What should I do

I have a Toyota Aqua 2014 hybrid. I had no symptoms at all. I took it in to the machanic to have my muffler checked and a hissing noise when I reverse or tune my steering wheel.. After they hooked up the diagnostic machine unto the car I was told I need a master cylinder

@raimag7dtd766 18 дней назад

I'm not sure if this has been mentioned but another symptom of a bad brake booster is if you have brake fluid running down the front of the booster below the master cylinder. This means the booster is leaking and putting vacuum to the master cylinders rear seal and drawing fluid past it.

@BubbleBlastKidz 2 месяца назад

Diaphragm of brake booster is torn if you hear hissing when you break. If you hear the sound without pressing down on the brakes, then it’s likely to be because of the brake booster plunger seal.

@ScarabChris Месяц назад

I'm a very mechanical guy but I'm stumped on this one. I have a 2008 Escalade. Brakes were perfect, I even put on all new rotors, calipers and pads about a year ago and brakes have been super smooth and worked perfectly. But last week I had to really stand on the brake pedal to keep from hitting a car that pulled out in front of me. I wasn't going fast, maybe 10 MPH or less. But since then the brakes want to stay engaged under certain conditions. If I come to a complete stop, the brakes release fine. But if I lightly press the brakes like to slow for a turn or to go over a speed hump the brakes lock. They don't "lock" as I can't move the truck, but when I remove my foot the truck continues to slow down and come to a stop on it's own. A quick firm press on the pedal and it releases but driving is a pain. The pedal seems to not be retracting all the way up in these conditions. I can put my foot under the pedal and pull up to release it. And of course when trying to drive the truck with the brakes lightly engaged I get all the ABS, traction control warning lights. Any thoughts?

@AlanKaruzo Год назад

the brakes in my car (Opel Astra) work ok, but since some time ago the noise only occurs when pressing and releasing. There is no noise when fully pressed or released, or when it's pressed halfway. The noise occurs both when the engine is on and off. The brakes pass the test, BUT the noise appeared. is this a possible problem in the future? Here is the video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C2P89jiYrAk.html
