Today we'll be showing how to test and replace the brake booster and the brake booster vacuum line. The vacuum line tends to be an easy repair for most vehicles. The brake booster is a bit more involved, nonetheless, it's certainly something the novice mechanic or dyi can accomplish at home.

Well you just saved me $449. I had almost zero brakes. Maybe 5% and it was stuttering the engine idle, trying to die on me. It was just some little T barb in the vacuum line had a cap fall off. I put my finger there to plug that open T and the idle improved. So i found a screw and rubber.and made my own plug, and brakes working as should again. Thanks!!! P.s. i just so happened to have a Honda Vtec too (08 CRV), so the similar visuals made it super easy to check lines As a note for others, my brake pedal was extremely solid and wouldnt barely move up or down even with tons of force applied. Having car running, they felt the same as the car off. All that power lost from a tiny hole in the line. Now I'm back in action! Thanks again!!

I'm having this same hardness issue with my brake pedal, except when I press brakes slight the idle goes up, and when I press the pedal really hard the idle drops to normal idle

Thanks, I just changed the master brake cylinder and driverside brake line, both front side calipers and brakes in the front (driverside caliper wasn't opening fully dragging), bled the entire dark color brake fluid system out too, but still not 100 % I believe it's the booster, the brake pedal area I hear a air noise...I have the new brake booster in my garage ready, ill do your trouble shooting first, thank you sir!. Details: just got my truck 2nd hand 99 F150 V8 4.6 ABS 230,000 miles

A few days ago, I changed the cooling fan in a Kia Soul I bought from my nephew. To do that I had to remove the intake. When I backed it out, I noticed a very hard brake pedal. I could hear a hissing sound. After watching this and a few other vids, its pretty obvious a line is disconnected or perforated. The brakes worked fine before the cooling fan job. And I was about to drive the damn thing to a Kia dealership. Many thanks.

Check your seal on your master cylinder where it bolts to the break booster. Or it could be the master cylinder it self. Or your booster.

I've followed the steps in your video to check for leaks but I couldn't do the clamping of the hose because there is no valve except for right at the booster!

Thank you. I believe my brake booster hose has some sort of o-ring and I’m afraid that of I pull it too hard, I’m going to break the fragile plastic components on the hose (N52, 2007, BMW 530i). I’m chasing a vacuum leak and a smoke test revealed nothing. My plan was to remove the hose and cover it with my thumb to see if my short term fuel trims got better. But you just gave me a better idea! I can just pinch the soft portion of the hose to accomplish the same test. So thanks again!!!

Thank you for this clear and easy to follow video. For the first test, my break pedal went DOWN at ignition off, then stayed steady. Other tests were the same as in the video. There is no warning light, but with ignition ON the brake pedal hisses and is too easy to press, and this happened very suddenly. 2018 Outback. Edit: after some additional research, I believe the check valve may be right where the hose attaches to the booster...but I'm not sure, there is also a hard bump in the hose that may be it (I assumed it was the bump for the clamping test) I will try to find instructions to remove and check it.

@AudreysKitchen Жыл бұрын

Hey Marie. Any results to report? Thanks

@marieq3668 Жыл бұрын

@AudreyCooks actually I ended up taking it in, and it turned out to just need new brakes (pads and discs). After they were done, the pedal feels normal, and it only hisses when I press it when already fully stopped, not during normal driving. They told me such hissing is normal, and demonstrated on another car (a Legacy). I'm still sure it was not doing this before, or at least no where near as loud, but since I now only really hear it right before I turn ignition on, I guess that's OK. I also confirmed a 2020 Forester did it, which made me feel better. Maybe it's a Subaru thing?

I have a 07 Tacoma and randomly my brakes will lock up while driving and the only fix I found is to unplug the vacuum off the booster for a few seconds and this usually lasts a while. My factory booster did this and now my rebuilt used Toyota OEM one started doing it after about three years after being installed.
