Good point, I didn’t think about the parking break causing the problem. I almost never use it.

When I hear hanging up or dragging I think not releasing completely. That is what confused me.

Usually a sticky caliper or traction control issues show on one side or the other. They both cause problems with wear and heat but not usually equally on both sides. How long were the R12s on the car and what fronts were you using?

I don’t see where anyone said the rear brakes were consistently locking up before the fronts. Am I missing something?

It sounds like you have covered all the bases on rear brake heat management. If they are boiling it has to be either dragging calipers or you got ahold of some old brake fluid. It is unlikely they are dragging equally. Temps ons the street would lead me to the same conclusion as you dragging...

Also, what fluid are you running and when was it last changed?

Okay, so it doesn't sound like advance track is manipulating the breaks causing heat problems. Do you have stock rear rotors and are you still running the dust shields?

When you say off do you mean you push and hold for several seconds to disable it or just push the button once and let go?

Are you running with traction control on?

I'll take a 2x. You can hold it and I will get it from you later.

That is one drawback to living in the south now, but at least I don't have to shovel snow anymore.

I prefer Tim Hortons to Dunkin.

The new motor sounds good. Hopefully it fares better than the last one. Do you have any ideas on what caused the timing chain failure?

Installed without a pinion is not a good sign. I wouldn't use it. Chalk it up to experience and take the loss.

I tried RPX on the rears and they didn't hold up. I don't think the RP1 would fair any better. I think the SR series would make a difference, but they were not available for my calipers at the time. I am not sure if they have expanded the line since I tried them.
