Anti-seize on brake caliper bracket?

[mrgrim007]

I just got done rebuilding the front-end on my 2002 Suburban (ball joints, pitman arm, etc.). The bolts that hold the brake caliper bracket to the knuckle always seem difficult to remove.

This time around, I decided to add anti-seize to each of the four bolts.

Now I’m second guessing myself and wondering if I should take them back out, clean off the anti-seize and possibly add some loctite instead?

Thanks

Okay, that makes sense. Thanks.

Almost sounds like the bolts were undersized and stretching, then loosening up. The loctite wouldn't really address the issue, but it would keep the bolts from then falling out.

Pretty rare for caliper bolts to just fall out, but not unusual for the recommendation of loctite on those bolts. I agree that blue should be perfectly fine in most circumstances.

DRV issued a recall on the Kodiak caliper slide bolts because they were falling out.

The specified RED loctite. Overkill IMHO, I always use BLUE.

I know DRV can mean Mobile Suites, but I didn't know they also made brake calipers.

Slide bolt threads should have medium loctite, and YES properly torqued. DRV had a recall on the subject.

Bolts don't loosen up because they are lubed up. They loosen up because they are not properly tightened.

Think of rod bolts in an engine. They are in lube all the time 24 hours a day and they don't loosen up or have loctite on them. They don't loosen up because they are torqued properly.

X2. Use anti-seize on the caliper bolts and torque to manufacture spec. I was a Saab mechanic and never had a brake caliper fall off a car ever.

If you looked close you might have seen the loctite on the bolts when you took them out. Loctite and proper torque is the right way to do the job. At the very least, Proper torque. Brakes are very important to get right.

At least that's my thoughts.

Brake caliper bolts and slides should use Sil-Glyde silicone grease to keep things lubricated and rust free.

The Pro I used for 40 years used anti seize on slide bolts and mating surfaces on calipers.

Thanks for the replies, I won’t worry about it anymore!

You'll be fine. Have been using anti seize on spark plugs, glow plugs, brake caliper bolts and many other things for decades and have never had one work loose.

You shouldn't have a problem with anti-sneeze. If your worried about them backing out, drill a hole in bolt head and put a piece of safety wire thru the head and tie it to something close.

I use anti-seize on the spark plugs on my Harley, as is required, and have no issues with them loosening. Your brakes should be fine.
