I got this... (I'm a diesel mechanic, ABS specialist.)Some older (junked) school buses had early version abs that required a pump that could be pulled off separately for service (which never needed it). One of these pumps would give you AMPLE braking power. They're made to run on 12v systems, even weatherproof. All you would need is two hydraulic T-way solenoids to re-route each rear wheel cylinder to either the vehicle factory system or the pump, as per arduino command. The arduino can get is traction control signals directly from the wheel sensors.Here's how:First, the anatomy of and ABS wheel sensor. - Most common wheel sensors are actually just a magnet with a coil wrapped around it. This sensor when placed close enough to a rotating sensor ring will distort the magnetic field of the sensor. This causes a signal to be generated but only when the wheel turns.Second, the Arduino. - Having inputs tapped from the wheel sensor, the arduino looks for one input to go silent. (Stuck wheel, other wheel spinning wildly.) The Arduino then fires up the pump, activates the solenoid for the spinning wheel and clamps the brake until the other wheel rotates at a similar speed. (Usually within 10% tolerance.)Tada. Basic traction control the way industry does it!Advanced traction control is just more signal evaluation between the all four wheels plus throttle reduction, ABS is just traction control applied when the brake lights are on.Hope it helps.
