TV? What's that? Kidding of course. Those deals can kill a business. You're either a TV show, or a business, rarely both. When the show runs its course, than what? Retire? They don't pay that well.
Oil deflector at 2:00 is actually the way you protect reed valves from fatiguing, breaking off at the root and then of course since they are no longer there to function, from failing to function. It's a common thing to see those curved backing plates on reed valves, if you've seen more than maybe three 2 stroke motorcycles. To NOT have them is old school and I've dated myself again.
I had a 4th gen F body that when the brake booster failed pressurized and slammed the pedal to the fully up position. 200lb dude in good shape and with 2 feet I couldn't stop it. Backing down a hill toward my neighbor no less. Good to see GM has improved this system since the late 90's...:/
And the last sane GM engineer will say, "Why? What happened to Hydroboost, that's a pretty reliable sys..." and before he can finish the sentence the other engineers shoot him with a tranquilizer dart and ship him to Siberia.
I think what the GM engineer should have done was make a generic electric module, hide it under the dash, call it generic but charge twice as much for a replacement as the original cost of the vehicle, and make it where no one can replace it without a hand written note from Major League Baseball! Or, a power module, that is totally integrated, that supplies power to everything, and need to be replaced every time a fuse blows, and then need two hand written notes from Major League Baseball, to replace it! Ooooh, I know, they should design a manual cooling fan, that you need a 40 pound 4.25 inch wrench to loosen up. Let's just hope the government comes along soon, and makes everyone put a tire inflation system in every car, that requires a masters degree in extra-terrestrial reproductive systems, and a bachelors degree in South Pacific micro organism marital habits,(bachelor, marital habits, think about it) to be able to inflate the tires!! Perhaps we need one of those special passenger door lock modules, that no one can prove exists, yet causes the engine to not start, and makes it look like your neighbors wife is the problem!! I remember when the power steering pump was engine driven, and the power brakes ran off of vacuum that the engine already made!! At least we get 3 mpg more than we did 30 years ago!! Coincidentally, we pay 30 times more for the cars, than we did 3 years ago! But, at least we can look at Facebook instead of where we are going, now! I was sick to death of always having to steer and brake and pay attention to my driving!
Engineers from every car company: Our newest, high efficiency engines don't produce enough vacuum, we need to install a vacuum pump or completely electric brake booster.
Probably the kids of the GM engineers who came up with the powermaster electrically boosted brakes of the eighties. Let's replace the great hydroboost with a electrical motor, that will fail with little to no warning. Oooh, let's but it on the fastest street cars of the time too (Grand Nationals and T-Types)!
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.
At 2:08 you make a valid observation, "pictures speak more than word." For me, it would have been welcome to see rather than hear about the removal and installation of the pump; no matter how "easy" that process was.
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.
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
I also have a 2004 Tahoe with 276000 original engine rebuilt Tranny. It needs an encoder motor but as long as the service 4wd light is off it works great;)
Once, mon ami, I solved the neighbour's 'hard-brake-pedal' by discovering that both front hydraulic brake hoses had 'closed-up' (the inside diameter had shrunk), His son admitted to having added ATF, thinking that it was a grande replacement for braking fluid . Schmuck ! The red colour, in the reservoir WAS a hint. Of course all the rubber-bits required replacement too.
We work on a lot of these at my shop and I replace at least one a week personally. I've even replaced multiple pumps on the same vehicle in a years time . This was before the new design so I'm interested to see if the newer design last longer.
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....

Active Fuel Management (AFM) The throttle plates are open more to reduce throttle suction (pumping losses) in the engine, therefor lower manifold vacuum.
@@nwedrick GM's hydroboost used the power steering pump for fluid assist. These newer trucks are electronic assist steering. No hydraulic power steering, no hydraulic power assist brakes.
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
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.
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.
Still don't know why there's engine oil feed to the pump. Are they drawing the vacume from inside the block so they don't have to run a line to an external air filter?
I'm doing calipers in my '93 940 right now ... for the SECOND time. Company sold me A1-Cardone remans back in March '17 - first, the right rear locked up solid in August of '18, to the point where I could remove the caliper, start the engine, and STAND on the brake pedal with ZERO movement of one piston! 5 months later, I'm doing the left rear, & replacing the fronts as a pre-emptive strike. Don't put Cardone crap on ANYTHING. They are the Dorman of rebuilders ... 😡
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
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.
My 2015 Sierra had the same problem amongst others ...at around 40000km . In an underground parking lot . Got lucky I didn't hit anything. Traded it In for a 2017 f150 . If that fails me ... turning to toyota and never looking back . And I've always been a GM ford guy ..
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
How many people will get seriously hurt or loose their life before GM makes this a recall? Let's make a SMA subscribers poll on how many months before a class action shows up on this!
After a few people die or some lady putting groceries in her trunk gets knee capped when someone pulls in behind her...then just maybe then they will have a recall.
No more "bump into the person in front" stops for this lady. Lol. Actually have brakes again. Scary how long it was let go before brought in. I bet it was driven there, instead of towed in too. Lol
Interesting difference between the original pump and the replacement. I would hope that there is an improvement in function and longevity with the new pump. I absolutely hate installing a part that you know is destined to fail again. If the part has been improved.... well..... hopefully things are looking up. Thanks for the followup. I am assuming that a stretch fit belt is installed while installing the component is being put in place? Could you clarify with a video sometime as to what it is and how to install it?
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....
Say Eric. I have a 08 toyota 4 runner SR5. That I'm working on. But need a wiring diagram for the 4 wheel drive /front Actuator. Any chance you can tell me how I can get one on the cheap. Or were you go fof the ones used by YOU. I will watch the. W.U.W. on 1/9/:19.
Eric, I wondered how there was a follow up with no previous video but your link shows that you "premiered" the first part and when you do that no notification is shown (bell). I wonder how many views are lost by creators doing this.
You have to get a go pro and use a mount of one of their types and use some lighting from above and maybe narrate from below while you do the job? Just a thought I had as the steering wheel shaft would be out of the way.
Active Fuel Management (AFM) The throttle plates are open more to reduce throttle suction (pumping losses) in the engine, therefor lower manifold vacuum
Vacuum is getting scarce in newer cars. Turbocharging, cylinder deactivation, late intake valve closing (Atkinson cycle) all eliminate or reduce the intake manifold vacuum under at least some operating modes. I don't think there are too many belt driven vacuum pumps other than these but electric vacuum pumps are extremely common today. GM, Ford, Chrysler, Honda, Toyota, BMW, etc. all use a vacuum pump on most of their newest vehicle designs. The latest trend seems to be to have electric assist on the brake booster so no vacuum is needed there at all (check out a video on Bosch iBooster for how these work).
Eric, thanks for the follow up video. I think I will put the new pump on as a precaution on my 2014 Silverado. Is the pump a dealer only item right now? I couldn't find it on Rock Auto. Eh... p/n 12669488. Just found the new one on Summit Racing.
When you say "take the steering shaft off", do you mean just disconnect the pinch bolts on the u-joint and the get the joint out of the way, or do you have to disconnect something inside ?
So what you're saying is they've made car where cadence braking is actually dangerous instead of being the fastest way to stop a car on a slippery surface in the absense of ABS? -i.e. you need working ABS to be able to do a panic stop in this car? Dumbing shit down so that everyone can use it has gone too far.
The Ford, Internationals had them back in the early 80,s and the GM / Oldsmobile diesel had them too back in the late 70,s to mid 80,s. I'm sure there where others too.

Why did GM reinvent the wheel and stop using engine vacuum for the brakes ?

Is the pump a dealer only item right now? I couldn't find it on Rock Auto.
Eh... p/n 12669488. Just found the new one on Summit Racing.
I would go with the GM pump on this. I've replaced dozens of them at the dealer, and the redesigned pumps hold up MUCH better
So is 67 degrees in January ? Did you move to LA?
2wd easy. 4x4 its a pain. I have both setting in my service bays
When you say "take the steering shaft off", do you mean just disconnect the pinch bolts on the u-joint and the get the joint out of the way, or do you have to disconnect something inside ?
Just take the pinch bolt off at the gear and pull it off. The part is master splined so it only goes on one way
So what you're saying is they've made car where cadence braking is actually dangerous instead of being the fastest way to stop a car on a slippery surface in the absense of ABS? -i.e. you need working ABS to be able to do a panic stop in this car?
Dumbing shit down so that everyone can use it has gone too far.
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.
why don't they have a holding tank to compensate?
It's Gm and that costs money
I took that pump apart and didnt see exactly why it failed. Nothing broken no scratches but significantly more vacuum
What, no airbag deployment after rear ending everyone in town?
this the first time i hear about vacuum pump with belt
Mercedes have vacuum pumps driven by the cam.
The Ford, Internationals had them back in the early 80,s and the GM / Oldsmobile diesel had them too back in the late 70,s to mid 80,s. I'm sure there where others too.
