I suspect the penetrants never get to where they need to be: The threads on the end of the bolt facing me. (For those not familiar with typical brake caliper setups, the bolts have a mostly smooth shaft, with threads at the end that screw into the caliper "body", said threads facing outward toward the wheel, but buried into that caliper "body". They are a long way from where penetrating oil can be applied.)

I have considered heating the caliper body in the location of the threaded portion of each bolt, but, I figure that will destroy the Neoprene(?) boots that protect part of the upper shaft of the bolt.

Any ideas?

I like Fords , just wanna get that out there.

Take 1 and 1/2 sticks of dynamite and secure to offensive mechanical area. Deploy detonator of your choice.
Clear area of women and children. Open one (1) beer and take a gooooood swig. Position yourself and the vehicle at least 75 yards away from anything you do not want destroyed or damaged.Take another goooood pull off of the beer and detonate ! Entertainment provided and problem solved.
Now, go purchase a new vehicle and properly maintain it !!

Snoot ;o)

Apply WD40, let it sit overnight, repeat, and then use an impact wrench or a normal wrench with a long metal pipe placed over the handle to give you leverage.

Another thought. After all these suggestions you probably can’t get enough torque on a breaker bar. Time to take out a bottle jack and use it on your breaker bar. If the bolt is that siezed it will break the bolt and at least you can move forward.

I had the same problem on my Ford. I used PB blaster, and a torch to heat around the bolt. Then I used an electric torque wrench.

I've watched my brother in-law heat the bolts with his torch to get them out.

These guys finally loosened a bolt using heat.

Heat the nut then apply candle wax to the top of it allowing it to melt into the threads. Should loosen up immediately.
