I thought I blew up my transmission because my truck would not move …….

My caliper fell off and locked up

damn both bracket bolts came out. normally you see one gone and it drags the wheel.

nothing gave it away ahead of time? noise? vibration?

One was gone I limped it up the street and snapped the other one pushing it up the shop driveway

Nothing I could hear over a aftermarket muffler and diff noise

I went to brake hard heard the loudest money sounding bang and then my truck would barely move if at all I thought my transmission blew on a hard downshift to stop

Only off thing was the soft pedal but that’s been a thing ever since I got my master cylinder done but I don’t think it was done correctly

The main tendence is bad maintenance...

Dang! Never heard or seen this.

Where the calipers ever removed at any point? I know the front calipers on my 99 Silverado specs are like 150 lb-ft or something like that. And the bolts have some sort of thread locker. Admittedly, I have only re tightened them spec but have never reinstalled any thread locker compound.

I've never removed the rears though. They are still the original at 270k miles. A long time ago my mechanic replaced an axle shaft that got bent when I got a curb on a patch of ice. I guess one rear caliper at least got removed and reinstalled...

Damn. It never ceases to amaze me how things fail…

Had a bonded brake shoe where the friction material broke free of the metal backing plate and rotated around in the drum until it wedged itself on the other side. Wheel locked up very quickly…. That was a PITA..

This is a first for me. Yikes!

You are right and especially these bolds never get loose when tight properly. There is not much vibration and due to the permanent heat change, water and dirt, they rather have the tendency to get rust tight, then to loosen themself. I would also speculate, they were never tightened properly, since last mount...

Kind of amazes me the torque values on some of these bolts and nuts. Old days just pull it tight and run it, 150 ftlbs is more than "tight."

 

[Scottydoggs]

even 20 year old factory loc tite still works well. them bolts take a lot to break free.

the main thing here is that critical parts like braking need to have proper bolt torque, over/under causes things like this.
millions of these on the road this should never happen.
It had to have taken some time for those bolts to come out, little by little there should have been some associated noise, click, clank, vibration, rattle.. something

And it seems like some blue loctite would have a good purpose here.

you'd almost think the bolts were cleaned off. even after 175,000 miles and new brakes every year on my 97 3500 pick up where you cant get the caliper pins out so you need to take the caliper with its bracket, every damn time it took way more force to get them broke free with the factory loctite still on there.

So that's enough evidence for an indictment. Who was the perpetrator?
