DBAs 4x4 Survival Brake Series design has been tested and proven in mines, police vehicles and recreational 4WDs, as well as being called on to do the heavy braking in rally cars and armored vehicles. Drivers of 4WDs or SUVs can improve safety and driving enjoyment by taking advantage of the greater stopping power and more consistent performance of the 4x4 Survival Brake Series. 4000 T3 slot design consists of a precise array of slots that have been formulated using the latest in computer aided engineering design software and extensive on-road and race track tests. The result is an amazingly quieter, more responsive, and smoother brake pedal feel. This is achieved from a series of tri-symmetrical curved slots, which when aligned in a specific way, drastically dampen the vibration harmonics or noise, which is commonly associated with traditional straight slot (groove) rotor designs. The tri-symmetrical slots also increase the number of out-gassing exit points for brake pad friction gases to escape through, further increasing the consistency and effectiveness of every brake stop.
