I would pay money to see the look on your drivers face when you tell him you went to CR4, an online forum, to find out what brakes to use on his race car.

Sorry, I couldn't help myself. You might get some valid info here, but I would get a second opinion before slapping the brakes on the car.

I'd get in touch with a go-cart builder and ask him what he uses on his shifter carts.

Or motorcycle brakes.

There's tons of brakes already designed. Why not just buy some?

Before we can discuss brakes, we need to come up with the proper design for the wheel.

I quite agree. At that weight and speed, brakes from a very small motorcycle or from a kart would do just fine. Could even get away with braking only the front wheels. Although, the F900 brakes mentioned elsewhere would be quite resistant to fading. hehe.

Separate master cylinders for front and rear is a novel idea. Will there be a brake pedal for each?

What I have seen of that design, they used a link between the two masters, and varying the link could bias the braking to front-rear as needed.

When I worked for the highway dept, we had some F900 Ford dump trucks. The trucks went for over 5 years, and never wore out the brakes. I think you should use them. I think they were 16" by 6" wide.

Use the smallest, lightest brakes that will just barely prevent fade when used harder than possible on the track.
