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 ๐Ÿ™„ Good thing we saw it first ๐Ÿ˜…
-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.

    Cardone sent me a caliper with out the plug.

  8. Avataaar/Circle Created with python_avatars Scott Nusser says:

    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!

  9. Avataaar/Circle Created with python_avatars James Stuart says:

    Bad design ๐Ÿ™

  10. Avataaar/Circle Created with python_avatars Dangerous Amoeba says:

    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! ๐Ÿ˜‚

    Nice, Iโ€™ve had banjo bolts with no hole in them , thatโ€™s fun

  13. Avataaar/Circle Created with python_avatars Steve Huetteman says:

    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.

  17. Avataaar/Circle Created with python_avatars Gerben Spruit says:

    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.

  18. Avataaar/Circle Created with python_avatars Donald Nye says:

    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,

  19. Avataaar/Circle Created with python_avatars Bob Spurloc does stuff says:

    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?

  20. Avataaar/Circle Created with python_avatars Benjamin Cresswell says:

    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.

    That looks like a inspection compliant rear brake delete plug for a that soccer mom that competes in burnout competitions on the weekend!

  23. Avataaar/Circle Created with python_avatars Frank Muschetto says:

    Nooo…that's GM's new anti-lock brakes. That plug stops the brakes from working hence avoids them from locking up.

  24. Avataaar/Circle Created with python_avatars erik_theautotech says:

    might not tighten down but i bet it buggers up the threads at the end of the bolt.

  25. Avataaar/Circle Created with python_avatars jack002tuber says:

    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

  26. Avataaar/Circle Created with python_avatars Don Munro says:

    That's a new one on me. Never seen that before. Great catch.

  27. Avataaar/Circle Created with python_avatars GlassVial says:

    Obviously that caliper is for a GMC, it's professional grade! The Chevy version of it would have a plastic plug, of course. ๐Ÿ˜…

  28. Avataaar/Circle Created with python_avatars John D S says:

    good catch and a great heads up. Thanks Eric.

  31. Avataaar/Circle Created with python_avatars Steven Sapyak says:

    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 couldnโ€™t 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 wasnโ€™t 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 GMโ„ข๏ธso long story short look over everything wellโ€ผ๏ธ๐Ÿซต๐Ÿผ

  37. Avataaar/Circle Created with python_avatars pilgrimpassingthru says:

    I would expect nothing less from the geniuses at GM .
    It's gotta save money , somehow

  38. Avataaar/Circle Created with python_avatars Wayne D says:

    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.

    Thank you Eric. That makes absolutely no sense to me. I think the parts engineer had too much time on his hands. Cheers.

  58. Avataaar/Circle Created with python_avatars Paul Stafford says:

    Did both the new calipers have the plug in them, or was it something accidentally left in place after testing?

  62. Avataaar/Circle Created with python_avatars South Main Auto Repair LLC says:

    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?

  63. Avataaar/Circle Created with python_avatars Alan Ganter says:

    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,,

    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.

  72. Avataaar/Circle Created with python_avatars RFDarter says:

    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.

  82. Avataaar/Circle Created with python_avatars DTWMTX 2011 says:

    Would be nerve-racking while trying to bleed that caliper!!!

  83. Avataaar/Circle Created with python_avatars Beรฑito says:

    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.

  84. Avataaar/Circle Created with python_avatars Tony Montana says:

    Been that ways for 30+ years. Itโ€™s the proper way. The metal ones are cheaper than plastic.

  85. Avataaar/Circle Created with python_avatars Brian Fuller says:

    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.

  86. Avataaar/Circle Created with python_avatars Dratchev241 says:

    can't be… GM spent money on metal? no way..

  87. Avataaar/Circle Created with python_avatars Aku2Dimensional says:

    General Maintenance sure are sneaky looking sort.

  88. Avataaar/Circle Created with python_avatars Crabman Rockefeller says:

    Was the cylinder / piston pre filled with brake Fluid??

  89. Avataaar/Circle Created with python_avatars Joe White says:

    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.

  90. Avataaar/Circle Created with python_avatars Scott Marshall says:

    So – that's how the new lifetime brake pad warranty works….

  91. Avataaar/Circle Created with python_avatars TonyP says:

    Look on the bright side; if it was a Ford caliper, it would have been welded shut.

  93. Avataaar/Circle Created with python_avatars ram50v8 says:

    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)

  94. Avataaar/Circle Created with python_avatars jimbo W. says:

    Is that factory part or reman?

  95. Avataaar/Circle Created with python_avatars jimbo W. says:

    With that fitting would have set the brake idiot light on dang quick..

  96. Avataaar/Circle Created with python_avatars Rodrigo Sagebin says:

    Can't believe they didn't at least put a big "warning" sticker across the plastic cap.

  97. Avataaar/Circle Created with python_avatars S C says:

    The dumb ass things they decide to omit to save a penny, then go spending a dollar in something that doesn't matter.

    Never seen that before.

  100. Avataaar/Circle Created with python_avatars vipahman says:

    That is ridiculous that a part like that was engineered just to be discarded. And not to mention the potential safety hazard. Weird!
