Race Driver Coaching

You can brake much faster than you can accelerate so the forces involved have greater potential to unsettle the balance of your car and cause loss of traction. Squeeze the brake pedal smoothly, never stamp on the brakes, and try not to get into the habit of allowing ABS to sort out locked wheels. This doesn't mean that you can't press the pedal hard, but ensure that the pressing and releasing motions are progressive. This will keep weight transfer spikes to a minimum and reduce the chances of unnecessary weight transfers or wheel-lock.



Graph 2 below shows the grip demands placed on the tyres by braking smoothly, yet relatively hard. There tends to be an early peak of force as the weight transfers forward (which is when wheel-lock is most likely to occur). Brake application should be tapered at the start and finish to avoids spikes on the graph.
