Would mounting a disc brake on to the drive shaft multiply the braking ability at the wheels because of the gears? Or would the disc need to have a large diameter to overcome the torque coming back through the driveshaft from the coasting vehicle? Just another quick qusetion, that I think I already know. Are driveline brakes legal for the road? Or does there have to be a brake on each wheel? If it makes any differance it is on a 1 ton truck.

A driveline brake would multiply the available braking torque, but it will not increase the heat dissipation capacity. For a parking brake it would work fine.
On a high performance vehicle, heat dissipation and wear are going to be the biggest problems, and fitting a small diameter transmission brake is probably not going to be a very good solution.
