Brake caliper question.
I want to remove the brake discs on my 2000 FRC. When reinstalling the calipers do the mounting bolts need either anti-seize or thread locking compound on the threads?

Service manual defines all four fasteners, caliper and bracket, as one time use, to be replaced every time they are re-used. Wow. I, too, use thread locker.

I decided to replace the fasteners but the smaller caliper mounting bolts were discontinued by Chevy but I found the same grade bolts in a local auto parts store under the Dorman brand. I ordered the bolts that fasten the caliper mounting brackets to the uprights from the local Chevy dealer (I was suffering a brain cramp at the time-shouild have looked on line). Part number 14084051 bolts came with a yellow threat locker already applied to them.

I reuse the large caliper abutment bracket bolts over and over . I use a wire brush to clean the bot threads and a 12 Gauge shotgun brass brush for the bracket threads. Then I use a small amount of LocTite BLUE threadlocker and tighten the blots up to spec. Don't use RED threadlocker!
You need heat to release that stuff.

I like the idea of a shotgun brush, also. I'm going to put various caliber brushes for different sized threads in my toolbox. Another excuse to buy more tools!

That's because the bolts supplied by GM for the brake components already have a threadlocker applied to them. So all a tech has to do is to tighten them to the correct torque spec.

I'm a rebel. I just re-install them and crank them down really tight again. Don't even torque them since it's a pain in the *** to try and get a torque wrench on them.

There are a lot of bolts where German torque works well for a long time. Sometimes I think accurate torque is an absolute, then remember working with axle bolts on my earlier Triumphs on the side of the road, using the tools in the under-seat kit.
