PSA: Check your caliper bolts

[tjkj2002]

Well one thing I can say I have never had happen,personally or at work.




Use Loctite is you wish but only use the blue stuff.I know GM uses Loctite from the factory but have not seen any others.

Caliper torque spec in the service manual is 11 ft lbs..

Oh, you are speaking of the bolts holding the bracket on, not the caliper. Those are 100 ft lbs. 11 ft lbs on the caliper mounting bolts.

 

[HoosierJeeper]

Correct, this is the bracket that bolts to the knuckle and it takes 100 ftlbs. Caliper takes 11.

This same thing happened to me in December completely destroyed the rim

I knew I'd seen a pic just like that recently…was driving me nuts.

Yep I was lucky it wasn't snowy out since the wheel completely locked up, it could've killed me as I was on a very small, crowded road

If they had been torqued correctly to 100ft/lbs, they wouldn't come loose.

Not really true,should but murphy always shows his nasty head every once in awhile.




The real kicker is how many actually use a calibrated torque wrench to actually torque bolts like those,I'd say less then 0.01%.I don't and never have but sadly that day will soon end since "torque to yield" bolts are almost the norm on '14+ model year vehicles.At least It will be a year or 2 before I start really messing with that crap but did just invest a lot of $$$ in brand new Snap On digital torque wrenches(3/8" and 1/2"),at least they have a great calibration program that does not cost a arm and a leg.

[LibertyTC]

followed by a Fsomethinsomethin... last brake change i noticed the threads towards the head rusted away so i picked up some new pins between changes.
