Wow! I just did a 2k trip from NY to TN and I couldn't figured out wtf was going on. For some reason it only happens a very slow speeds(traffic stops or parking lots) NOT at high speed. Thank you for the video.

[@SR71mydream]

There’s a number of videos on doing this, but yours helped/will help me the most. I’m just hoping I don’t find oil up in the booster.

[@pianistasalsero]

Thanks, I hope everything goes well.

[@robertmyers1039]

Thank you for this video! My truck experienced this problem last week (2016 Silverado) and was in the shop for 3 days. This was the issue and I was able to make sure the dealership did the right thing. Thanks so much!

[@Yosoy1an]

Is a recall now! .. I just got my letter for my 2015 gmc sierra. I don’t have those problems on my truck but that’s what it said on the letter, stepping hard on the pedal to stop the vehicle. Good video, well done!

[@pianistasalsero]

Get it done before it fails. It is scary as hell to loose breaking on such large vehicle.

[@mk2mike]

I had a bad pump, random hard braking w/ LOUD ticking... replacing my pump fixed it. Thanks man

[@pianistasalsero]

Thanks! I just wanted to help, I knew I was not the only one with this problem.

[@lespratt5294]

Just finished up doing this to my 2015 GMC Sierra Denali 4WD. It was much harder since it was 4 wheel drive. There is no way to access the rear bolts from the bottom at all because of the 4 WD components. You have to access both of them from the top. The only way to do that is to remove the bottom section of the steering column. Still very difficult to reach. Just an FYI for those that have 4WD on their truck. And I love the ending of your video! LOL. Made my chuckle after being so frustrated with this truck.

[@pianistasalsero]

It was tough brother but you got it! Mine is a 2 wheel drive and was still hard to do. I'm glad to know my video helped.

[@daTruckTeam]

What was the torque specs for the bolts?

[@lespratt5294]

Thanks bro this is a huge help and loved the ending you should do all DIY videos!!!! We pay 50 to 60 grand for a vehicle and have trouble 55,000 miles GM should be ashamed

[@pianistasalsero]

Just trying to help brother. By the way, my transmission went out on us recently. The stock oem torque converters are crap. Check your transmission fluid and change the filter. If the fluid looks a little bit brown it means trouble in the making.

[@drestion]

@@pianistasalsero i just replaced the pump because of a ticking noise while accelerating. It seems better now but i can still hear the ticking noise about 40% of the time. Could it be the torch converter as well? how did you know your torch converter went bad? thanks!

This was a huge help, thank you Sir for making it! Ending was hilarious as well!! :-)

Carl Anderson thanks! Just trying to help. Too bad we spend so much money on these vehicles for them to fail so prematurely.

I know, this should definitely be a recall item. I'm thankful my wife didn't rear-end someone. She had to literally stand on the pedal to stop.

[@carlanderson6845]

For my 2015 Suburban, to make room to remove the vacuum pump bolts, I needed to remove the steering column elbow joint. Also, I didn't replace the vacuum hose. So far, so good!

[@TheChaseclear]

Awesome assessment and explanation of the problem / solution. GM really screwed the pooch on these newer trucks and SUVs from the A/C system design (which will fail because the factory condenser won’t hold the pressure), to this braking issue. I’ve also had problems from my 4WD switch and my drivers seat will adjust itself randomly at times. Thanks for the helpful and entertaining video. Good to know there are still plenty of people who like to work on their own vehicles while the pansies sip their lattes 🤣

[@pianistasalsero]

Just trying to help, we paid a lot of money for these vehicles. Keep an eye on the transmission, get it flushed and serviced before 50k. Our transmission went out after the breaking problem.

Thank you for the video, it would have been better if you showed how you did it as you did it.

[@pianistasalsero]

If you need a video of the minute by minute process and steps in order to replace this pump, then this video is not for you. This video was targeted to those with good mechanical abilities who just need someone to point in the right direction with sound technical tips on parts and tools. I at least hope it helped you.

[@TheJcrandazzo]

Good video, but why did you have to replace the pipe ?

[@pianistasalsero]

Just in case, the cost to replace it was low.

Thanks my frined ., i have 150 k miles in mine 2015 yukon ., i might change this shit any way ., even though is not failing yet ., and yes this video did help . Thnaks :)

[@jenniferwelch972]

Awesome.. unless you have 4wheel drive ...but managed none the less

[@XxGlistenxX]

Well I work at a gm dealership it's a open recall just the pump no other parts needed but it does help if you change your oil on time

[@felixsoto5807]

Loved this is there any way that you can delete pump and use engine vacuum

[@blainedavis5811]

You have to disable active fuel management in order to remove vac pump from equation. Because it shifts from 8cyl to 4 cyl

[@joediaz9861]

This is why more people would rather hold on to their older model vehicles. The new ones are extremely over priced and parts/labor for repairs are usually more than the monthly vehicle payments. A one or two year old shouldn’t break down so soon

[@charles9571]

I'm starting to buy only older vehicles because by the time you're the owner, KZbin is full of maintenance videos for common problems with that vehicle.

[@roymasters8335]

Thanks for the video, it was helpful. Fair warning though for others that the 4 Wheel Dr. version is much more difficult because the differential blocks most of your view of the bolts. you will want to swivel ratchets and many combinations of extensions and or swivels in order to make it work and a lot of patience but it can be done. also do not buy the belt removal tool from Napa because it is garbage and does not work, nor does the belt installation tool that is part of the same kit. The tool on Amazon looks different maybe its ok. good luck!

[@stilo_lara5378]

I just completed replacing my vacuum pump. Before i drive my truck i’m curious if i need to bleed my brakes?

[@pianistasalsero]

No, your breaking fluid is a separate system from the vaccum system.

[@scottmahony4742]

I am having the opposite problem. the petal goes to the floor. I have changed pads, Rotars, and master cylinder. Took it to another mechanic and he is saying the issue is this vacuum pump.

[@geesehoffa2144]

You can borrow vacuum pressure off the intake manifold and run it into the master cylinder. No need for the pump. I did it to my 2017 Tahoe. Only thing is the brake pedal sometimes feel like you are on snow at very low speeds (I drive in NYC), but the truck stops no problem as if it had the original pump working. It’s a permanent fix if you don’t mind the once in a while kickback in the brake, or a temp fix until your part arrives but can still confidently operate the truck knowing you can stop no problem.

[@geesehoffa2144]

If you get the right tubing there’s no kickback in the braking, my tubing forks off towards the, so the vacuum pressure isn’t precise to stop the occasional kickback, but good enough for “on the dime” stoping.

[@pianistasalsero]

Good luck with that. I would not recommend it.

[@geesehoffa2144]

Thinking about it - I’m better off with my repair. Your pump will go out again, my intake vacuum will last the life of the car. Can’t risk the pump failing at another 50k miles at the wrong time. Traditionally the vacuum pressure is taken from intake manifold anyway. No pump needed.

[@pianistasalsero]

@@geesehoffa2144 if you read more about the breaking problem, you may be able to generate enough vaccum from the engine, however, when it goes into 4 cylinder mode, the vaccum decreases not providing enough for proper braking. I was told the new pumps are much better.

[@geesehoffa2144]

Oddly enough when my pump went out and I didn’t have the manifold work-around I didn’t have any braking issues. It was only at lower speeds (less than 10MPH), basically city driving where lots of “stop and go” happens. I asked my dad about it (he’s a mechanic with 50+ years of experience) and he told me the engine rev increased the vacuum pressure even though the pump was broken. So at stop and go speeds the engine is working in v8, it’s only v4 when you coast. I honestly don’t notice any difference in stopping power in neither the city or highway, if anything on the highway the car braking is working as if the pump never went out at all. And again I drive in NYC - it’s absolutely hell here for driving.

[@OnRezOn2]

Do you have to add or empty the oil?

[@pianistasalsero]

No, no need to empty the oil. You will get some oil to drip out when you remove the old pump. Great question!

[@sheeks88]

How did you determine that it was the pump and not the booster? From what I can see I do not have any oil leaking under the pump or in the hose line. I disconnected the hose line like you said and did not hear and pressure being relieved. I have a 2014 Silverado. The brake peddle would harden up but with giving it RPMs the peddle would soften. Today the brakes are rock hard even with giving it RPMs. Did you happen to experience any of these problems?

[@sheeks88]

Also thank you so much for the video. This is the only video I could find and it’s super helpful

[@pianistasalsero]

If you don't have oil leaking into the booster through the tube the problem most likely is your pump. Unless you have a leak in the tubing. I changed the pump and the tube. Problem solved and greatly improved the breaking.

[@pianistasalsero]

By the way, at the end of the video you can see the internal damage to the pump. The original pumps are crap and Chevy knows it.

[@sheeks88]

Almost bought the booster. After Watching you video and reading your advice I’m pretty sure it’s the pump. Thanks so much for the help

Yes, no problems after the repairs. Actually the breaking improved tremendously.

2 wd. For a 4wd may be more complicated.

Pianista Salsero yea I’m working on a 4 Ed and have basically no access to the bolts on the back of the pump. Might have to remove the steering shaft to get to it.

Don't know where are you going with this kind of question. Please read the bulletin, it explains in detail the purpose of the pump. Your question should be directed to the engineers at GMC.

Because in 4 cylinder mode you may not have enough vacuum. Its a stretch in most driving conditions but nevertheless its possible

The problem of GM engines has become annoying and the engine is already old Maybe since 2000 GM hasn't changed and Ford and GM must change their engine policies and collaborate with the Germans and Japan to make long-running engines in the 1960s, 1970s, and 1980s. The American engine was a legend until it was crushed by Japanese engines that live for many years without maintenance We have in Saudi Arabia great interest in the Japanese engine and its development to make engines for military equipment as well as fun in desert cars
