Caliper bolts backing out

[Will Schaubert]

Hi, I have a 2014 SHO just recently on 7/24/20 I got new pads and rotors from power stop and had them installed. Last Friday I was driving and heard a quick ticking in the front right then a loud bang, the car couldn’t move. I come too find out the top caliper bolt back out and the caliper fell forward into the inside of the rim and was dragging. I luckily had a friend who knew cars and came and put another bolt on, I went too the place that installed them and brought it to their attention that the bolt came out and they stated that had nothing too do with them and a vibration backed it out. I read a couple places that thread lock glue would have prevented this issue if they put it on, is that something that needs to be put on? Again only the rotors and pads were replaced so it is weird too me that a bolt that has been their before never backed out in the past. Ford just inspected the other calipers and said that they were put on totally wrong and that the back caliper bracket bolts he could loosen with his hand. My main question is thread lock glue something that they should have been put on? Any thoughts please, this is a whole sh*t showfor me.

Yes they should have lock tite

To replace the rotor, the caliper has to come off, or at least (if possible) disconnected on one side and moved out of the way.

The bolts should have loctite, I usually use red loctite on all brake hardware. Contrary to popular opinion, it does come apart

However - if they torqued the bolts properly, they wouldn't have backed out so soon. It's not like if you don't put loctite on them they just fall apart. You don't want it to fall apart no matter what, so you loctite everything.

They did something really wrong. Find the manager, owner, whatever, explain that you could have been killed, and the stuff just came apart. I wouldn't even trust them to make it right. Go to another garage or a dealer, get it fixed right, and hand them the bill.

They must of goofed pretty bad. I didy brakes and I dont torque any bolts. Just good n tight. Never had a brake issue from what I've done. They must have not double checked everything.

Yeah I give them a few uggas and never had any issues. Sounds like they didn't tighten them properly

This type of thing is why I do brakes myself. I do not trust anyone else to do it correctly.

Lives are at stake...not just your own.

Eek yea that's scary af. I personally use blue loctite, I don't have to use the power of Thor to break it loose.

Don't ever go back to that shop again for anything. Also learn how to do brakes yourself, they are easy.

Even if you don't, local car clubs are all over and most are willing to help. Before COVID we had monthly tech days where newbies could get help installing stuff and the more experienced could get a hand to do the big stuff. Was pretty fun too.

The caliper slide bolts are torqued to 55 lb-ft and the anchor bolts are torqued to 122 lb-ft. The anchor bolts are technically one time use and I suspect that is due to the factory installed lock time.

I've never seen anyone ever replace those bolts in 30 years of wrenching on cars.

I always put my old box end wrench on the bolt, hold the wrench tightly on the bolt head with my left hand, and hammer the wrench with a 4 lb hammer until it's tight. I do the same to get them off.

Just did brakes 2 nights ago helping someone out. That car had the most frozen slide pin I've ever seen. I had to put the bracket in the vise and use a impact gun, forward, reverse, over and over until it finally spun and we got it out. Would have replaced it, but parts stores were closed. Cleaned it all up as best we could, threw a bunch of brake grease in there and it worked great.

Yea they are not like some head bolts that actually twist at the torque spec. Just good and tight and it will last for a long time
