2014 – current gmc / chevrolet : hard brake pedal – Auto Repair Chat

In this video I have a look at a 2014 GMC Yukon that has a customer complaint of a low brake pedal. It doesn't take long to duplicate the customer complaint and find the cause. These systems work off from a vacuum pump and they are a pretty common failure item. -Enjoy!

    Is there a vacuum pump delete that will allow you to tap into the intake manifold for vacuum ?

  2. Avataaar/Circle Created with python_avatars Huntergreen says:

    Change the oil an the brakes will work great for about 5000 miles… my 2015 does the same thing when the oil gets dirty… definitely a poor design by GM.

  3. Avataaar/Circle Created with python_avatars Tim Lewis says:

    Cool table what is it?

  4. Avataaar/Circle Created with python_avatars Nasearh RS says:

    Ma brake assist keep showing on screen plus the ebs and traction sign came .. for info I changed all the dram wheels and brakes pads and did new brake oil so any idea what's the problem and how to fix it ?

  5. Avataaar/Circle Created with python_avatars WouterB76 says:

    Soooo VAG concern is not the only one to overcomplicate things apparently…

  6. Avataaar/Circle Created with python_avatars J Hall says:

    I had this issue with my 2016 GMC Sierra and 25 Feb 21 took it to the dealer. GM replaced all parts under warranty at zero cost. It's not advertised but if you take it to the dealer my understanding is that this issue has an extended warranty for 10 yrs/150,000 miles.

  7. Avataaar/Circle Created with python_avatars Thomas Szary says:

    Just delete the vacuum pump. Dont need it. Plug the holes and call it a day.

  8. Avataaar/Circle Created with python_avatars Donnie Robertson says:

    Great job

  9. Avataaar/Circle Created with python_avatars Allison Duramax says:

    You don’t have to buy a new belt. You go from the top of the engine bay to do it don’t go from underneath. Electric ratchet and 13mm and some short extensions and put it in place and tighten the back 2 bolts to pull it tight. I’ve done a countless number of these pumps.

  10. Avataaar/Circle Created with python_avatars BIG_BOSS says:

    dealer change it for me for free

  11. Avataaar/Circle Created with python_avatars mastertradeofnone says:

    Did they not recall this??? I got a warranty recall for it?

  12. Avataaar/Circle Created with python_avatars John L says:

    My 2012 Altima locks up the front brakes, first the driver side starting smoking, then I stopped to let it cool, then started again to get it home. Right inside the garage with 2 feet of the car still outside I heard a thud on the passenger side and that side smoked. The car wouldn't move because the passenger side was completely locked. The abs light also turned on when the car was still moving. Do you think the check valve is the culprit or the brake hose on both sides are clogged? I did notice when replacing the driver side caliper that the fluid didn't drip much out of the hose. Haven't taken off the hose from the passenger side.

  13. Avataaar/Circle Created with python_avatars dubj672 says:

    Just had this fixed in my 2015 Silverado and GM is now warrantying the new updated vacuum pumps out to 2025 or 125k miles. They were on backorder for a little while, but they're coming in again now. The recall is covering over 3.5 million GM trucks & SUV's.

  14. Avataaar/Circle Created with python_avatars Ashley Ashley says:

    Anyone hear of Chryslers having similar problems? I have a 2015 Chrysler 200c and have a hard locking pedal sporadically and it clicks when it happens!! Sometimes feels like my break pedals about to bust off lol

  15. Avataaar/Circle Created with python_avatars jaime hernandez says:

    They do a recall now for that I just got a letter on the mail with a code to take it to a dealership they may see your video and hear your question

  16. Avataaar/Circle Created with python_avatars Batscat says:

    If it wasn’t for gmc there would be a lot less mechanics.
    I know in my shop they are the bread and butter.

  17. Avataaar/Circle Created with python_avatars Simon flores says:

    i install all new front suspension on a 94 chey trk 5.7 when i completed the job i took it for a drive now it will not turn all the way to the left maybe 1 turn before it hit the stop how can i fix this problem please help

  18. Avataaar/Circle Created with python_avatars David White says:

    There is a new recall that came out today I guess. They were making it seem like it needs to be reprogrammed. Not sure how true that it.

  19. Avataaar/Circle Created with python_avatars Nick says:

    Another great product from Generic Motors

  20. Avataaar/Circle Created with python_avatars Huber's Ranch says:

    GM just finally issued a recall on the brake pumps on these vehicles.

  21. Avataaar/Circle Created with python_avatars Ajamant 371 says:

    I just picked up my 2016 Silverado 67000 miles vacuum pump issue fixed under 100,000 mile powertrain warranty. Backing into a parking spot and hit brick wall. Pedal to the floor. Make the stealership fix it

  22. Avataaar/Circle Created with python_avatars Q8_elite_services says:

    I miss my 1996 yukon.

  23. Avataaar/Circle Created with python_avatars Gerardo villarruel says:

    I have a 2017 Chevrolet, it’s at the dealership, for that same issue with the newer vacuum pump The thing is

  24. Avataaar/Circle Created with python_avatars Joseph Wash says:

    (Sarcastically) Yeah, today's vehicles sure are more reliable and longer lasting than older ones. It's things like this that make me glad I don't own a newer car. Today's car buyers are essentially being used as guinea pigs. If I see one of these newer GM vehicles coming up behind me and it doesn't seem like they're gonna stop, I'll try to get out of the way.

  25. Avataaar/Circle Created with python_avatars David Pruitt says:

    Maybe if she learned how to stop correctly in the first place and didn't creep ahead she wouldn't have hit cars. This is one of the most annoying things when I'm driving, someone that can't properly judge the stop or is impatient and creeps ahead. At least once a day I'll be at a stop light and the person in front creeps so far ahead there's enough space for another car.

    Get rid of all that "safety" crap like lane assist, backup cameras, and active braking and just learn how to drive your damned car.

    What an awesome design improvement….

  27. Avataaar/Circle Created with python_avatars 38911bytefree says:

    Its a 2014 and power brakes not working … GM.

  28. Avataaar/Circle Created with python_avatars Elton says:

    Gm will always find a way to make money off people

  29. Avataaar/Circle Created with python_avatars jhitt79 says:

    The brakes don't work but at least the touchscreen does.

  30. Avataaar/Circle Created with python_avatars jhitt79 says:

    If the engineers thought its a good idea to have a pump to supply vacuum. Why not just have the pump pump hydraulics?

  31. Avataaar/Circle Created with python_avatars never stop learning says:

    The Spanish meaning of GMC
    G= GRANDE(BIG)
    M=MALO(BAD)
    C=CARO(EXPENSIVE)
    lol. A friend's joke. Very true anyways.

  32. Avataaar/Circle Created with python_avatars John Doe says:

    I've been a professional wrench since 04 and I still learn so much from you Eric. I went into oilfield (Waukesha 9390ci engines and what not) and I'm amazed by what I miss out on in the auto field I left. Thank you sir, great video.

  33. Avataaar/Circle Created with python_avatars Kane’s Garage says:

    Factory GM cars are full of Chinese parts now. Even crucial parts like wheel bearings, etc..

  34. Avataaar/Circle Created with python_avatars HUBBABUBBA DOOPYDOOP says:

    I'M GOING TO HUG MY OLD BUICK NOW AFTER SEEING THIS

  35. Avataaar/Circle Created with python_avatars Snake Skin Productions says:

    Too much . Maybe time for a carrier change? Iv'e been doing this stuff for to long. How long? Let's just say that when I started there were still points ignitions on the road. Might be time to retire? I can say "welcome to Wal Mart…lol

  36. Avataaar/Circle Created with python_avatars Justin Rutledge says:

    Eric, do you still have your Launch Diagun IV? How do you like it? I am trying to decide between that tool and the Autel MaxiCOM MK808TS… do you have any insight you can offer? This is for advanced DIY use. I personally own Ford, Buick, BMW, and Toyota… so it would certainly be used on a mix of cars. Family owns a number of GMs as well…

    Buy a Toyota, problem solved.
