How hot is your car's brakes?
I made a mistake when I didn't let my brakes cool down before I worked on my car because the bite to my hand from the heat of the rotor meant that brakes got hot.Do you know how hot your car's brakes get when you push your foot on the pedal or pull off some sweet skids?The answer is yes.
How do your brakes work?Think about the physical action you take.The braking process begins when your right foot lifts from the pedal.This allows for your foot's fancy work to move a little brake fluid to all of your calipers through a process called "hydraulic force multiplication".When you press the brake, you move an equal amount of fluid throughout your lines.
The next part of the line of work is the caliper.With the brake pedal depressed and the fluid moving through the lines, the pistons extend out of the housing and squeeze the two opposing brake pads.The process of applying friction to a moving assembly slows down your car.The micro-abrasive brake pads are created when the pistons squeeze them.
We can get to the cool part now that my explanation of brakes is over.
Fenske narrates a channel on the internet.Fenske puts his beloved 2002 Honda S2000 on a set of jack stands and pops the car in gear in this particular video.He uses a Flir T1K thermal camera to show the amount of heat that is generated as the wheel hub assembly rotates.The handbrake is pulled when the car is revved to 3000rpm.The amount of heat that moves through the rotor is shown by the thermal camera.Fenske explains that during heavy track day usage, the brakes could potentially rise to nearly 500*C (932*F) under the right conditions.
