NASCAR braking

[Goosemaster]

I was watching speed channel yeesterday..they had some "ebhind the scenes" show talking with NASCAR mechanics. Anyways, they showed a clip from the undercarriage to a car as it was braking, and the brakes got BRIGHT BRIGHT orange fro mthje heat. My question is, if I were to slam the brakes in my car, would I get such results?

I don't want to put a camera under there anything. Just interested in how much braking/friction is needed to generate that much heat..


Thanks

If anyone has any clips too, that would be nice😀

In a racing situation, it is very common for brakes to heat up rediculously like that. In a normal driving situation, if your brakes get that hot, you should slow down.

An I was going to get open-rims to showoff the glow:|

Thanks

If you were braking from 150mph, your rotors might glow red if you had very very high friction pads.

What you're seeing isn't necessarily from the speed but rather the constant braking. You'll see that on just about any race car after a few laps. The pads have a bit to do with it also of course.

they're designed to work at that temp.. they don't stop well until they're hot

^^What he said. You won't notice them glowing until after a lap or two on a tighter oval. On something like Daytona or Talledega, you won't notice the brake's glow at all (no real need for braking other than when coming into the pits there). On something like Watkins Glenn (a road course), you will see them glowing very constantly. This is why if the fuel carrier spills gas, he won't be in for a fun night.

Watch some WRC footage sometime and you can catch some glowing hot rotors. Especially during special stages that are run at dusk and/or night. They make extensive use of left-foot braking and they pretty much never let off the throttle to keep boost pressure up, so it makes their brakes work even harder.

Edit: Clip in Quicktime format - Some Subaru promotional video from last year. Anyway at about 11 seconds through there's an Impreza rally car going around a bend and you can catch a glimpse of the glowing rotors through the spinning wheels. That's all I can think of right now.

In 1985 carbon brakes were just starting to be used on aircraft.

In the last 19 years their use on hi-speed racing vehicles has been fully embraced.

Carbon pads on iron discs or for the full house treatment, carbon pads & discs.

For street use carbon is not a good set-up, because they only work well at elevated

temperatures. At low temps they can be dangerous. Carbon discs are much lighter

than iron, a big plus for racing. They glow because their working temp is 2500 F +.

For more info Google carbon brakes or carbon carbon brakes....🙂
