First he got the regen braking so hot it failed and then the regular friction brakes weren't DESIGNED to handle the full job alone.

It EXPECTS to be balanced action between both braking systems.

It was not meant to be raced.

He probably did everything right on the brake install and bleeding.

When you are having too much fun racing, things break.

Yesterday I was at the drug store and one of those 1987 Buick GNX sedans went by rippin through 1st gear, having fun.

When I came back out of the store, he was limping back slowly the other direction, with an awful lot of oil smoke in the exhaust.

That's having too much fun.
