2nd Gen Non-Engine/Transmission Caliper Bolt

[madmanmanick]

The other day while driving my truck down the interstate the lower bolt that holds the caliper in on the front right tire came out and the front right tire locked up. I had just conducted a brake inspection and had torqued the bolts when I put them back in. The only difference between this time and the others was I put anti-seize on the bolts. Normally I don't, but they were extremely hard to get out this last time. Is anti-seize not supposed to be used on the caliper bolts? Also has this happened to anybody else out there. The Dodge dealership that did the repair work was really surprised that this happened.

I thought about this when I did my ball joints. I too slathered the anti-seize on. I hate trying to get things apart after some time in the mud and water. Input would be helpful if anyone knows for sure.

I also would like to know as i put anti-seize on mine during the last break job because a bolt broke when i was trying to remove it... .

I didn't put anything on my caliper bolts when I did my ball joints recently, but am thinking I should have put on something like blue Loctite. That is the one that requires less break-free torque than red Loctite, isn't it? It should also prevent rusting in the area it occupies between the internal and external threads. I avoided anti-seize 'cause I feared what happened to you.

My non-expert opinion is NO anti-seize on threads. You need some friction to keep the nut from unwinding. Blue Loctite is locking and is a better choice for protecting threads. Red Loctite is permanent (you use heat to soften it).

I agree no neversieze on bolts/screws. Living in the North East and maintaining my own vehicles I have found that neversieze when used on brakes and e-brake mechanisms tends to wash off.

I use grease or heavy oil (50/50 stp & oil mix) on all undercarage bolts to stop corrosion. I then spray with white grease to seal from road spray.

For brakes I use permatex brake caliper grease which I have found to last far longer than Never S. It will keep the e-brake mechanism and pads free & functioning for a full year when applied to all pivot & contact points.



For the caliper bolts I use my oil mix or the brake grease.

I have done 100's of brake jobs & never had a bolt loosen.



You can also add loctite for added protection an oiled bolt. It just lessens the loctite bond.



Question;

What is the difference between a screw & bolt??

To me, if it uses a nut or a threaded receiver machined into the companion material, it is a bolt. If it makes it's own hole/receiving threads as it is tightened, it is a screw.

Then what is a hex head/ socket head cap screw?:-laf

ditto. Except for lag bolts.

As a matter of interest, here in the UK I refer to a bolt as one where the thread goes about half or two thirds of the way up the fastening, but the top section is unthreaded. If the thread goes all the way to the head, I call it a "set screw". Standard screws are tapered end fastenings into drilled holes in wood or metal.

misnamed, that's what
