This Is What Melted Brakes Look Like

A 3,400-lb race car, street pads, heavy foot, 3 1/2 hours of endurance racing on a hot day? Read what happened to Andy L. during our Park Bench Racing team's third driving stint at the July 21, 2014 Chumpcar race --

"During my driving stint the brakes started to feel funny and not work right. After going over 100 mph down the front straight, I started braking for turn 1, brakes popped and lost most of their effectiveness. Decided to go straight and take escape road and stopped before reaching the end. Safety crew escorted me to pits where we found brake pad worn out, rubber boots melted/burnt, and backing plates against the rotors. One piston melted/wore through backing plate. That piston was the one that popped as brake fluid was leaking from it. Put caliper back together, bled brakes and installed an old set of old brake pads to get our next driver out on the track."

A backing plate with a shape that resembles a slice of bacon from this angle... 

... and looks almost transparent from here.

 Rubber boots melted off - we were probably lucky the brakes didn't catch fire
and witnessed a small miracle with Andy getting us back on track.
