In this video Josh was getting ready to install some OEM rear calipers on this '17 GMC Terrain. They way they plug off these rear calipers it could be easy to miss the plug and install the brake hose ๐ Good thing we saw it first ๐
-Enjoy!

All right folks, just want to share something with you. Got this: GMC Terrain Here and my guy Josh is doing some rear brakes on rotors, pads and some calipers. Now the original calipers. You can see somebody got after them.
They're wadded up, the boots are tore off. or at least on this one anyways. I'll show you that's how it came into us. no brackets, but came with a new caliper now.
I come over and help my guy swap over the parking brake motors. Not a big deal, a couple of screws and I just happened to look at it I glanced Down in the Hole Maybe you can see it? so that's where your banjo bolt goes. Typically they got like a little plastic plug if you get them from Cardone or whatever. but GM and their Engineers are tricky little guys because they put a plug way down inside there and I'm pretty certain I'm not 100 certain.
but I think your brake hose in your bandeau Bolt There's not a lot of threads there. It may have been able to go around in and tighten down and give you the sense that everything's all good so you don't have any brake fluids coming out. I Guess what I'm getting at is have a little look-see because look what that little tricky engineer you did GM I bet he's laughing all the way the bank when he made that plug. um I could be wrong.
Perhaps the banjo bolt doesn't go in far enough to tighten down, but that'd be pretty dang embarrassing to have that sucker still in there. It's like now your brake pedal is hard. you got no fluid to the back. So anyhow, be warned.
Watch out for them tricky engineers.
When I replaced mine on my 2010 Equinox I bought new Raybestos calipers and it only had the red plug. I'm kind of shocked you can buy new GM calipers but that must be a much newer model than mine.
"Tricky" Engineers? I have other adjectives for them! lol
The internet reckons the GMC Terrain are built in Canada … Ingersoll, Ontario .. is that a French Caliper?
Half the battle is the physical inspection of all components .
Probably the same engineer that put plastic timing chain guides in motors where a beautiful steel chain flies through at warp speed lol
I need a plug bah hah
Cardone sent me a caliper with out the plug.
Great catch. That's attention to detail! I learned that as a nuc machinist mate on nuclear submarine about 40 yrs. ago. That's a great example why you must study your new parts!
Bad design ๐
Not my story but MAYBE due to a lot of calipers coming in with rust (cos threads can't have coating on them) or bits inside the thread, as i was told from a parts guy. Calipers master cylinders a few other things even some engine parts like solenoids i've seen with hex plugs just like that.
That would take forever to bleed! ๐
Nice, Iโve had banjo bolts with no hole in them , thatโs fun
Eric, It may not have been the GM engineer. No way anyone on the assembly line is removing that on every part. More likely it was the caliper supplier, added for packaging the service part version. Yes, I am one of those damn engineers (not brakes) at an auto company located here in the Auburn Hills, MI area.
Excellent tip , I would have never even thought to look for that ๐๐๐
good job boss:
Ding, Ding-Ding… we have a winner in the GM stupid idea of the month contest !!! ๐๐คฃ๐๐
A couple of weeks ago, i got a calliper for a Chevy Bolt EV, that one had also a blind plug inside. But the bolt did not fit till the end. Even it's a nasty plug… Keep up the good work! It is satisfying to watch and learn from you! Greetings from The Netherlands.
I would like a better look at the plug and the hole. I will assume the plug keeps oil in for shipping and the plastic cap is to keep dirt out and protect the treads and sealing surface,
pffft all I see is $$$$! put it back take car for test drive crash into bush, sue GM with damages of as u hit the bush it made you scream like a girl but u identify as mostly dude. isn't that how things work today?
Place the Blame where it belongs. Management gives the orders & engineers follow them or they're gone. Management have the last word befor it goes into production.
Mr O. complaining about Government Motors engineering? Who da thunk it! ๐๐
That looks like a inspection compliant rear brake delete plug for a that soccer mom that competes in burnout competitions on the weekend!
Nooo…that's GM's new anti-lock brakes. That plug stops the brakes from working hence avoids them from locking up.
might not tighten down but i bet it buggers up the threads at the end of the bolt.
If GM were so inclined to like include some directions with the part and the mechanic was inclined to like read them, then it'd be ok. Sounds like a couple of shooting stars at once, I know
That's a new one on me. Never seen that before. Great catch.
Obviously that caliper is for a GMC, it's professional grade! The Chevy version of it would have a plastic plug, of course. ๐
good catch and a great heads up. Thanks Eric.
WOW Thanks
Wow that is very scary ๐จ
2.8.23. I just did a rear brake job on a 2002 GMC 1500 Sierra long bed, And the parts were sourced from Napa, and I found out I couldnโt build up or bleed any pressure from the passenger side caliper, so I thought well I must be something in the antilock brake system, so I went and did the other side, and just for grins, I had my buddy pump up the brakes, and I tried bleeding them and lo and behold I could bleed them! I was quite surprised I thought, so. I traced out the brake lines and they were tied to a common line coming back from the antilock brake system, so it wasnโt four wheel. Antilock! I looked further, then I took off the banjo bolt and had him pump it, and I noticed fluid just squirting out quite quickly. I then took the caliper off and observed in the hole, where the banjo bolt goes, and found that there was barely a8 inch hole in the very bottom I could see the piston, and there was no way in hell that fluid was going to get behind that piston as it was being retracted so I could put new. pads on the rear calipers! It was made that way originally from the factory as it was shipped or they were new calipers, but were GMโข๏ธso long story short look over everything wellโผ๏ธ๐ซต๐ผ
Well Done Thanls A+++++++++++
Seems they're tryin to make $ for the dealerships when some diyers get frustrated
and can't figure out why they're brakes don't work
GM JUNK!!!!!!!!!!!!!!!!!!!!!!
Holy crap
Who would've thunk that….!?!?
I would expect nothing less from the geniuses at GM .
It's gotta save money , somehow
My guess the plug is put in if the hole is drilled too deep in the manufacturing process to save the caliper from being scrapped. Tapping and plugging saves a few bucks and doesn't effect the function of the part.
what is happening to your channel … 777k subscribers.. i mean you can't complain but theres got to be some reason.. the algorithm likes you
You could by ten plastic plug with that one metal one.
What a Bloody Stupid Idea, could kill people.
I had this happen to me.
Imagine when GM goes full EV? Them things are going to be running wild, zapping people on the streets and exploding on their way to taking their drivers to jail for something mean they posted online. Its going to be awesome!!
GUUUD EYE
Did the instructions mention the metal plug?
Wow
That is dangerous.
Thanks Eric Iโll pass the tip on ๐๐ โ๐ง
Potential accident waiting to happen!
Don't reinvent the wheel!
Idiot and total retard engineer!
Don't have gmc but thank you
That is a hell pf a note.
good catch, Josh.. thanks for the info Eric
Wow ๐คจI'll jus quote highway gunny [Clint Eastwood in Heartbreak Ridge ] what a cluster F _ _ K
they should have a note in the box to that effect and a warning about the plug
Why on earth??????
Omg. At Least paint it a high viability color jeez
Thank you Eric. That makes absolutely no sense to me. I think the parts engineer had too much time on his hands. Cheers.
Did both the new calipers have the plug in them, or was it something accidentally left in place after testing?
There is a special place in hell for automotive engineers and I bet that there is a special lock so they will never escape!!!
Engineers!!!!
Whoa! That's crazy! I would not have seen that
Kind of interesting really. You look in OE service info and nothing in there about it but Josh did mention that the new OE caliper did have fluid in it. Perhaps it is some sort of QC testing and then they seal it off when finished?
Have a handfull of these plugs in my toolbox, perfect for capping lines off when you have it open and working on it, but dont want to leave it dripping, Or draining the compete system out,,
that there is some serious retarditis!
Just a test to see if you're paying attention….GOTCHA HA HA! Oh wait…
Woah Neelie! I had no clue about that, thanks for sharing ๐ณ
Interesting, to say the least. Good catch buddy. You have a good eye. Greetings from the Old Jarhead in WNC
Hiya Eric
Good catch….that would have been fun if it sealed and you couldnt get any fluid….
Darn those engineers . They can do harm with their enormous heads
What possible reason would GM do this? I've owned 16 GM vehicles over the 50 yrs I've been driving, but no more, it's Toyota or Honda only.
Not only GM's. I, as a car mechanic in Germany, came across of calipers with these.
On my first on I was like >why can i not tighten the brake line to the caliper???< only then i found the screw in there.
GM Train wreck
Whoa good tip!!!! THANKS๐
Dueling, banjo bolts
Wow. Good find. Iโll look for that. Thank you.
Me GM engineer. Me play joke. Me put plug in bottom of hole. Another banjo bolt is broke!
๐๐๐๐๐๐๐๐๐๐๐๐๐๐
Your forth brake is only there as a backup anyway. 4 separate brakes are overkill for cars these days anyways. ๐คฃ๐
How engineers fuck with mechanics, volume 157…
good psa
Would be nerve-racking while trying to bleed that caliper!!!
On Euro cars they r often pre filled with breakfluid because their inner space is a bit ''warren'' and can easy trap air bubbles. If there is air in the caliper you have to take it off to hold it in a specific position to bleed it fully. Acording to serviceinfo. Maybe that is the case here.
Been that ways for 30+ years. Itโs the proper way. The metal ones are cheaper than plastic.
Probably pressure testing the unit backwards through the bleeder hole. Reason being is if it passes the pressure test it's complete, back out the test fitting, install bleeder, AND THEN REMOVE THE ALLEN SOCKET PLUG.
can't be… GM spent money on metal? no way..
General Maintenance sure are sneaky looking sort.
Was the cylinder / piston pre filled with brake Fluid??
I sincerely doubt GM makes makes their own brake calipers. They might spec them and they buy them in bulk to get a lower price. They may have spec'd the plug, or maybe the caliper manufacture did it on there own.
So – that's how the new lifetime brake pad warranty works….
Look on the bright side; if it was a Ford caliper, it would have been welded shut.
GM keeping mechanics on their toes for generations!
๐
WOW, I ran into that decades ago and have not seen it since…. Until now! I always inspect fittings ever since I got bit on my first one. Amazing what you can find hiding in there, like a broken drill bit (seen that a few times)
Is that factory part or reman?
With that fitting would have set the brake idiot light on dang quick..
Can't believe they didn't at least put a big "warning" sticker across the plastic cap.
The dumb ass things they decide to omit to save a penny, then go spending a dollar in something that doesn't matter.
That's exactly why I stopped buying "American".
GM parts engineers strike again.
Never seen that before.
That is ridiculous that a part like that was engineered just to be discarded. And not to mention the potential safety hazard. Weird!
