Wash everything in a baking soda and water solution to neutralize the acid before it does more damage. At least hose everything off. It does not look great.

Your thoughts on the brakes are appropriate and a thorough inspection of the brake lines and caliper should be performed. Pay particular attention to the piston seals and the caliper pins and connection bolt holes.
If by "threaded tubing" you are referring to the wire wrap, then yes I did find some damage. One was actually melting. I've neutralized and rinsed all of this all this a couple of times, but more is certainly prudent. I hadn't really considered bolt holes, etc., but of course that should be an area of genuine concern.

Weekend rain and distractions over, Today, I'll be getting into all of this with gusto, beginning with the driver's side brakes, calipers caliper pins, rotor etc. I've changed the brake pads once, so I'm looking on YouTube for some helpful videos. I'm thinking it might be best to get a new caliper, rather than trusting the affected one any further. Naturally I'll replace all the brake pads on the truck as well, not just the front left ones.

When I have the left front tire off off I'll have much better visual and physical access to the affected area. At that point I'll spray everything with more baking soda and water and rinse it again.

I'm a bit concerned about the ECM which is located on that side of the engine block.

Kevin: When you mention Corrosion Protection are you still referring to priming and painting?
