In a recent video https://youtu.be/YE3kcGAXqJE I diagnosed a GMC Yukon for having a hard brake pedal making it very difficult for the owner to stop the car and actually causing her to hit a few other vehicles. In this video we confirm the diagnosis and repair. -Enjoy!

    hey was that yukon 4×4??? my 17 sierra is 4×4 and back bolts are hard to get does removing steering shaft give me room for back bolts ?

  2. Avataaar/Circle Created with python_avatars Chief60 says:

    Does anyone know of a vacuum pump delete, to run vacuum off the intake manifold to never have to worry about this ever again ?

  3. Avataaar/Circle Created with python_avatars Apocalypse2383 says:

    This was a worthless video with showing how to do it!

  4. Avataaar/Circle Created with python_avatars OSDCrusher says:

    I've worked for a Chevrolet dealer for ten years and changed an ungodly amount of those vacuum pumps. They are one of the dumbest designs I've ever seen. If you own a 14-18 GM truck or suv, you should delete the vacuum pump entirely.

  5. Avataaar/Circle Created with python_avatars juan romero says:

    Do we have reprogram anything? Like a sensor after replacing it?

  6. Avataaar/Circle Created with python_avatars Timmy Timmy says:

    they make a pump delete kit. you have to first reprogram the pcm to for the V4 crap and make it stay in v8 mode, and then the kit has 2 threaded plugs to cap off where the oil comes into the pump. then you just take some 3/8 fuel injection hose or some type 3/8 hose that won't collapse under vacuum and it hooks to the manifold via the pcv fitting. Badaboom.

  7. Avataaar/Circle Created with python_avatars ecleveland1 says:

    It normally takes a few deaths and the media picking up on them and the design flaw for a recall. GM doesn't care because it's not costing them money in court costs.

  8. Avataaar/Circle Created with python_avatars Joni English says:

    how long should this Pump LAST ???

  9. Avataaar/Circle Created with python_avatars Joni English says:

    now GM PUT ELECTRIC POWER MASTER CYLINDER with ELECTRIC PARKING BRAKES !!!!!!!!!

  10. Avataaar/Circle Created with python_avatars Assessor 12 says:

    Wow – and I had always wanted one of those big clumsy Yukons. I wonder if her insurance took a hit because of all the rear-enders….or how many little kids nearly got “Yukoned”.

    …as you say Eric, I guess brakes are optional when you’re out “finding new roads”.

  11. Avataaar/Circle Created with python_avatars Joni English says:

    Hopefully the NEW ELECTRIC ZF (IBC) POWER BRAKES will Solve this PROBLEM !!!!!!!

  12. Avataaar/Circle Created with python_avatars Fordgpw1942ocalafl says:

    The Chevy dealer over here has put 10 vacuum pumps and brake boosters in my dads suburban the booster squeals and leaks air in one time the pump locked up the other times the pumps were knocking it’s a bs system when all they coulda done was get vacuum from the manifold

  13. Avataaar/Circle Created with python_avatars James Grate says:

    Great video on the (GM Recall about the air pump failure), have you done any other GM trucks, or SUV's produced after the 2014 year models, let me be more specific, anything regarding the 5.3/6.2 Ecotec engines having a rough idle, or engine shutter in "drive" mode and stopped for a red light or stop sign and sitting for more than 30 seconds? GM issued a bulletin about this occurrence, and recommend a shim be applied to the Motor mounts, or replaced if the vibrations continue to occur. I would love to see you do a video about this issue, and see how you would diagnose and fix the problem. Thanks in advance….

  14. Avataaar/Circle Created with python_avatars Joni English says:

    DAM!!!!!!!!!!!!!!!!
    just Sold my 2010 Dodge Grand Caravan Se ( upgraded the Brakes to 2015 HD Brakes- 2 Piston Calipers ) – No Real Issues except for AGE
    now just Picked up a 2017 TAHOE LS – and have to Deal with Recal BS with a Vacuum Pump
    WTF — GM

  15. Avataaar/Circle Created with python_avatars Haroon Shabbir says:

    Hi, thanks for the video. When you removed the steering shaft did you remove it from the steering box and the intermediate shaft?

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

    FYI: stealership fixing my vacuum pump today under powertrain warranty. 2016 Silverado with 67000 miles. Special exception, normally not covered by powertrain but they see the class action law suit building.

  17. Avataaar/Circle Created with python_avatars Marco Antonio Monroy says:

    Shity pump I've replaced several on gmc's

  18. Avataaar/Circle Created with python_avatars Justin Speer says:

    Good stuff man….exactly my problem been looking for info on repairing myself thanks!!! Hoping it gets recalled soon!

  19. Avataaar/Circle Created with python_avatars Justin Dead Eric says:

    Did one of these today, removing the steering shaft made all the difference. Thanks for the tip! I also had the LF wheel well apart (did the washer pump too) some good camera angles with that out of the way.

  20. Avataaar/Circle Created with python_avatars MarkPdot says:

    Soooo, now has electric power steering and belt driven vacuum pump??? Wow GM engineers really thought this through didn't they? 🤔

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

    I have a 2017 Chevy 1500 with the newer vacuum pump,it’s at the dealership with the same issue the thing is That it only has 3800 miles on it, and the dam thing is leaking oil too from the wheel gasket ,still under warranty

  22. Avataaar/Circle Created with python_avatars jeffrey Rye says:

    I remember fixing vacuum pumps on ford diesel back in the late 90s. Just think most of them were converted to mini buses. There never were any recalls.

  23. Avataaar/Circle Created with python_avatars briantii says:

    Great video! > 250k subscribers, Nice job Eric O!!! Hopefully you guys did something nice to celebrate clearing a QUARTER OF A MILLION viewers. So freaking cool. Keep up the great work.

  24. Avataaar/Circle Created with python_avatars Big Dog50001 Automotive says:

    Well the good news is we saved a 1/10 of a gallon of gas because of this new fuel management system! The bad news is we smashed up grannies Cadillac because we didn’t have any brake assist on our 4 year old vehicle….

  25. Avataaar/Circle Created with python_avatars Leon Automotive says:

    Yup, issue with all 5.3 GDI engines years 2014 to 2018, I've change several per month take off the backing plate you will see what the failure is….

  26. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Great recap Eric O

  27. Avataaar/Circle Created with python_avatars haroldlm64 says:

    👍

  28. Avataaar/Circle Created with python_avatars David Ellenbaum says:

    eric did you happen to check booster for brake fluid leaking from the master . seen this many times . use the dip stick method also adds to slow recovery

  29. Avataaar/Circle Created with python_avatars reaper asylum says:

    What would people now a days do if they were back in the 60s and 70s when they had no power brakes shit I'm still driving around in a truck that didn't even come with power anything, that's how you test your skills right there slick

  30. Avataaar/Circle Created with python_avatars Louis Koponosh says:

    Lol pictures speak more then words lmao that's funniest one so far. Good job Eric always enjoy your videos

  31. Avataaar/Circle Created with python_avatars throttle bottle says:

    300psi on the brakes when not stepping on pedal? sounds like an issue with the booster valving or something, but maybe side effect of ABS system.

  32. Avataaar/Circle Created with python_avatars Bill Burkart says:

    Thank You for the follow up. Merry New Year

  33. Avataaar/Circle Created with python_avatars Lon Willis says:

    Interesting… Good Job !

  34. Avataaar/Circle Created with python_avatars Steve Fleck says:

    Thank you for posting the follow up!

  35. Avataaar/Circle Created with python_avatars Joe Acfalle says:

    At a glance, the belt doesn’t look as it has a belt tensioner, so how do you install the belt?

  36. Avataaar/Circle Created with python_avatars MrWhitestew says:

    So… on my Chevy volt, they use electric over hydraulic brakes, and it's a $24,000 car after rebates. A mid level yukon is around $60,000. Come on G.M. brakes are kinda important, even after the warranty runs out.

  37. Avataaar/Circle Created with python_avatars like a rock cm says:

    Every time I put a scope on a gm ,the only code it gives me is LOL.

  38. Avataaar/Circle Created with python_avatars Arthur Fricchione says:

    Another good follow up thanks for your time and effort. Stay warm ❤️

  39. Avataaar/Circle Created with python_avatars ŚŃĨРĔŔŚЖ says:

    I have the same tahoe 2009 engineer diagnosis as vacume don't know the vacuum or the bosster sensor could be

  40. Avataaar/Circle Created with python_avatars Darwin Dwelle says:

    A very good way to get people killed!!! WTF was GM thinking here??

  41. Avataaar/Circle Created with python_avatars Adam Trombino says:

    The ol' hydroboost system worked better and lasts a heck of a lot longer than these GM vac pumps, for certain.

  42. Avataaar/Circle Created with python_avatars Auto Manuals says:

    We have had a good number of emails in regards to this problem.

  43. Avataaar/Circle Created with python_avatars WhiteShadow2k1 says:

    I didn't even know it was possible for the brake pedal to get hard after "pumping" it while the engine is running.

  44. Avataaar/Circle Created with python_avatars The Shortman says:

    Did we just get the old "one thing led to another" video ?
