Stripped Brake Caliper Bolt Hub Threads

I think the problem comes up when you get to a certain number of cycles (brake changes) on a set of aluminum alloy tapped holes. If you are rushing this at the track and working with dirty threads then the probability goes up.

Galvanic corrosion. Steel bolts in Aluminum. That's what we're dealing with. If you can limit contact with oxygen you can prevent it. I've had good luck with anti-seize, and others like to use oil-based paint. Many people swear by Tef-Gel. I've never tried it, but it's made specifically for applications like this.
