A lot of disrespectful comments. I think you did a great job explaining and sharing your knowledge. Thank you.

Very good! You explained what we need to hear, thank you.

Thanks man! Helped narrow down some issues with my spongy break

Very helpful...I thought my Booster was bad because my brake pedal would depress when car was idling. BTW Slippers are bad ass!!

Thank you for your explanation. Greets from the V8Lounge in Germany

My brake pedal booster was leaking vacuum and followed your instruction and now its back to normal. Thanks

Thank You, for those of us who aren't nearly as educated about cars and how all of this works, you did a good job explaining to me how and why all of this works and how it works. Thanks again!!! I appreciate the help.

great vid bro and great ankles!

Thanks for taking the time.............

I've had problems with my brakes going to the floor only in the winter time when it is cold. I was thinking that it could be the booster because the vacuum hoses may get cold and allow air to escape. I have also noticed that the car isn't idling well. I was wondering if anyone has heard of this and if my thoughts on the brakes going to the floor could be the booster vacuum hoses.

Thanks for this helped me diagnose weather it is the master cylinder or booster. Deffinatly seems like the master cylinder now

Amazing help!! Thanks a lot, especially with the codes

That was an awesome video.... very informative and to the point .....very well explained . ...keep them coming ....

Good job, well put ,not too difficult for the beginner.

Thanks much for the info. Trying this next!

Great video man. I definitely got a good understanding on how to the brake power booster operates. Thank you very much!

at 3:47 you can hear air as you push the pedal down is this normal? as my car does the same thing

Great video. Thanks for posting

What was the hissing noise thats a problem im having and it's so annoying?

Indeed.

Good video, thanks for the tips

Measure the height of brake. Press brake down measure. Should be a difference of number. Start vehicle, put in drive, pump brake a few times, if it goes all the way to floor and doesn't give pressure/resistance to rise back up. Park and turn off vehicle. Pump brake, check height again.

Thank you brother very informative video 👏👏👏👏👍

Question sir. My car stalls when I stepped on the brake and I can hear like air releasing after I stepped on the brake. I have a Mazda Demio 1998

No offense you had me falling asleep for the first 2\3 of the video. That happens a lot when I watch self-help videos lol. But you woke me up at the end when you mentioned the lean codes 0171, 0174. My van has been pulling these codes for a while and now it worked it's way to the brake system. I have a vacuum leak somewhere. I hate diagnosing vacuum leaks they're a real pain in the but. The best way is the smoke method. Anyways thanks for the video. I did pull a couple helpful things out if it.

well isn't it that if there is a hiss sound when pushing the breaks that indicates for going to service? especially the the hiss sound wasn't appearing before..

Thanku very mucho for this video, now I searched hi & lo on here for some kind of help on how to find out if my break booster was damaged, now on my 2003 suburban I'm getting a service brake booster on my instruments cluster but brakes are working fine & after this test you posted even more so so wat eles can it be please reply help

I did the tests and it seems good but when i press it always makes a hissing sound and the breaks don't want to work that great and i have two lean codes in both banks

I heard sounds of air when you press the brake pedal while the engine is on. Is that normal? My car sounds the same thing

Ok so my booster passes these tests but on occasion while driving on the highway mainly the brakes will slowly apply themselves. I usually pull over and disconnect the vacuum hose from the booster which instantly frees them up and lasts for a few days up until a week or two. This problem started with the OEM booster and I replaced it with a rebuilt OEM unit which lasted 5 years problem free up until about last week where it started doing the same thing. My check valve is good, master cylinder is new, front rubber brake lines new. I have a 07 Tacoma 2wd auto no attachments on my MC or booster like stability control, no ABS light on etc. Would you say it's safe to say it's another bad booster?

can you help me figure out why my brakes don't work after I drive my car for 15 20 mins. when I hit the brake peddle after that amount of time the peddle goes right to the floor and if I shit my car off and keep pressing the peddle it sounds do like I hear air escaping out from underneath the car. it's bizzare. but then if I wait like an hour, get back in the car and drive the brakes are fine u til another 15 20 mins and then it does it all over again.

Hello friend how are you excellent video, but I have a question. The sound that has when braking that is like pulling air is normal in the brake booster of the 2004 trail blazer?

What if brake pedal sinks when you shut off engine with pedal depressed? Also strange noise is coming from brake booster at that moment. Could it be defective diaphragm?

my pedal goes to the floor when I turn off my car. I also have code p0102. when I turn on my car, the pedal doesn't move. I am thinking replacing booster after vacume leak check.

Great video ! thanks

Good video, good information.

I have a 04 vw passat 1.8t fwd and my pedal won't fully come up it stays down about a quarter inch cause the brake to rub the rotors and obviously initiate the brake lights would this be the booster?

So - is this un-filtered air from the cabin going into the engine ?? . I have an 03 Envoy and need 2 feet on the pedal to stop, and I hear a great sucking sound along with RPM increase, which fights the braking effort as the engine wants to drive the vehicle forward, especially in parking lots.

Im getting p0171 and I think this is the reason... can that also cause erratic rpms at idle? thank for your great video

Looks like this will likely be my issue. Getting lean bank 1 and 2 codes even after replacing the MAF sensor, o2 sensors, fuel filter, ignition coils, spark plugs, all of the intake gaskets, ccv/vacuum diaphragm, and cleaning out the fuel tank. I have high fuel pressure because the pump is screaming... I guess it's trying to send enough fuel to keep up. I hope I can find a good deal on brake booster. I was kinda hoping it was just a vacuum line lol. The odd thing is that my idle RPM is normal according to what I've read and I've been unable to find a vacuum leak with carb cleaner... make no sense... I'm going to check it just to be sure. could maybe be the valley pan gasket...? I don't get the error codes right away after resetting the computer, I drove out almost half a tank of fuel before it came back on...

helpful for me. forget about all the negitave comments. you have a lot more views. I'm shure this was helpful to a lot of people.

Do you have to use nitro to get booster system carried out to pump to pump ,or can I use shoe string measure ment

Thanks for the video it helps! thumbs up!

good way to check, but u could still have an internal vacuum leak in the booster. if theres a vacuum leak in the engine, pinch off the vacuum line, and if the engine runs better, the booster is bad. simple way to rule the booster out if youre looking for a vacuum leak.

Good tip !

I don’t have a lean code or any check engine code and when I check the brake booster with my foot on the pedal and hold it for 20 seconds it goes down a few inches. If anyone can tell me if I may have a bad booster check valve ? I have no fluid leak. I’ve had this problem a while now and am in need of help solving it. Anyone help please.

A lot of negative comments and likes don't do justice to this video, this was informative nothing wrong with it..!! And thanks for sharing this..!!

My favorite part was when you were pointing to the carpet!

I had P0171 and P0174 codes on my 2015 highlander with only 6000 miles. After arguing with the dealership about NOT putting E85 in my car they finally took the time to troubleshoot it and discovered a vacuum leak with the brake booster. My cause was the errors came on right when I was idling to a complete stop. Air would be pulled in the brake booster and lean codes popped up. Great video and wouldn't care if you wore heals and explained the problem.Nice job!

What if your brake booster loses all vacuum when car turns on?

great job- pretty thorough! Don't stop! Thanks Why don't the complainers make a video?

Mine stays solid when car is off. Goes down when on, but then slowly settles down further and further as if there is a master cylinder leak. But why doesn't that cylinder leak when the car is off?

Anyone know if the air sounds at 3:40 are normal?

3:37 is this air sound normal for brake pedal?

What's that hissing sound when you press the brake pedal....is that sound normal... My brake pedal is making the same sound.... My mechanic says my booster is bad I performed all you checks and booster passed

So if my pedal doesnt stop its a bad booster? I feel like thats easily misdiagnosed as a master cylinder failure.

Could this make a squeaking noise if its braking?

My car's brake pedal reaches the floor in order to brake and stop the car, accompanied with a (hissing) sound. So what's the deal here?

Theres a really smart mechanic that shows u 3 ways to check booster without even gettin out of ur car. Its only about a minute long. Press brake pedal 4 times n on 4th turn hold pedal down n start car. If pedal goes down then booster is workin.. U should maybe watch this guy n see how theres no lolly gagging...

What is the air noise in the cab

Wow, I Was gonna Close the Video Before it Ended, I'm Glad I didn't, Cos You Did Mention Something about Trouble Codes/Lean Conditions/Unmetered Air Going into the Intake, And That's Exactly What I Have, I Have Took the car To A Shop And They Couldn't Find Out What it is, But I know I hear the Hiss From the Brake Booster, But Idk exactly Where Its Leaking From, I Took the Hose Out From The Booster & Plugged it, The Hissing Stopped, But As soon As I plug It back into the Booster, It Starts Hissing Again. So How What Needs to be Replaced/Fixed? The Brake Booster Or What? Please Help. Thanks.

So if my brake padal goes to the floor almost but not quite when it's on. Does that mean its the booster? If you pump it will come back up but each time sitting still or on a hill I have pedal travel basically.
