Custom brackets, need outside help

[Uncle Ed]

I though of that but wondered if fins would collect mud and crud making a thermal blanket. either way I see your point. It would have to be driven pretty hard to transfer that much heat.

Another thing got me curious. In the pics you posted, the brackets appear to be fastened with bolts tapped into the brackets but the brackets show no threads. If they are countersunk allen bolts I don't see a shoulder in the brackets and that would weaken the attachment, anyway.

How are they fastened?

The top hole of the bracket is a through hole. Bolt goes through Caliper, through bracket, then screws into the spindle hole threads.

Very bottom one is the same way. Only the caliper doesn't bolt to that hole. So the bolt just passes through the bracket and bolts to the spindle.

The outside hole is indeed tapped. The bolt goes through the caliper and bolts to the bracket.
