jollyjumper, since I am using the Revo Nitro tranny, reversing the motor won't brake the car, it will just freewheel. So the disc brakes are necessary to stop the car. You need front and rear brakes because the center diff basically splits the drive train in two (front and back). I have the ESC set to only have forward speed and brake, no reverse. But the ESC brake action works the brake servo via a splitter (when the ESC sends a brake command the motor stops, but the tranny free wheels, but the signal is also sent to the brake servo, via the splitter, which works the likage connected to the front/rear disc brakes. It has very strong, consistant braking action that can easily be finetuned. I much prefer this setup (disc brakes) to the ESC/motor braking action in a normal electric car.
