You don't want to heat up the bolt. The bolt will expand inside the threads.

This only works coincidentally due to thermal transfer and differing expansion rates of the various metals. You have to heat the area surrounding the threaded hole. Besides, if you heat up the bolt too much it becomes brittle and useless. OK fine, there's a safety factor designed into most assemblies, but that's not the point. As a general rule: do not reuse a bolt that you've heated red-hot...especially not on a brake part!

Well the brakes are finally off on all four corners!

I now have to prep my calipers and caliper guides for sandblasting and powdercoating.

Should I soak everything in some type of fluid to clean them up before taking them to to get sandblasted?

I'm going to try to thread bolts into all the holes with threads so the sand doesn't do any damage...

Everything's been sandblasted and coated (expect the spring clips which will be done in red on Monday).

See attached pics for before and after...

Nice work!

Powdercoating was done by Simba Powdercoating, 235 Nugget Ave., Scarborough, 416 321 3909. $100 for the set of 4 calipers with carriers.

Here's a pic with the retaining clips powdercoated red.

I have all the rebuild parts, but can't find a good DIY on reinstalling the caliper piston & seals. Anyone know of a link?
