BRAKES ARE A SAFETY CRITICAL PART OF A MOTOR VEHICLE.
Brake components should be installed by a competent mechanic in a professional manner. Any incorrect installation of brake components can cause a major safety problem or an accident. If you are not a competent and qualified mechanic you should not attempt to install these products, but should take the vehicle to a vehicle dealer or competent automotive mechanic for their installation.
Disc brake pads and rotors are wear items and as such, should be inspected regularly and replaced as necessary. Read More.
The 4000 Series Wiper-Slot rotor has a unique 6x6 slotted design for extreme stopping power on the road and the track. As with every DBA rotor, the 4000 Series rotor bolts right onto the vehicle with no mechanical changes needed.
DBA's mid-series, enhanced-performance, slotted rotor features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring.
TSP is a proprietary process specifically developed by DBA for improving the performance of disc brake rotors. Benefits of TSP include:
- Improved fatigue resistance to minimize surface cracking
- Reduced rotor fatigue during prolonged heavy braking
- Quick replacement, minimal ''bedding-in'' of rotors
Thermo-Graphic markings are placed on the outer edge of each DBA 4000 series disc rotors and are used to monitor the core temperatures achieved during braking application. The markings change color as the rotor heats up to alert the driver to rotor temperatures that exceed optimum levels.
Initial Color | When rotor exceeds this temperature... | The color will change to... |
| | 458°C | |
| | 550°C | |

''Kangaroo Paw'' is a patented, high-tech disc rotor ventilation system designed and manufactured in Australia by Disc Brakes Australia and available on rotors for select applications. "Kangaroo Paw" technology delivers significantly improved braking performance. Even under extreme braking conditions. Kangaroo Paw rotor designs run cooler, are stronger, and outperform traditional straight-vane disc rotors.

The ''Kangaroo Paw'' design features a series of 144 diamond- and tear drop-shaped pillars and columns individually spaced between the rotor faces.
This system provides two key advantages.
First, is the ability to cool the rotor faster than ever before. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot air out from within the internal areas of the rotor.
Second is increased dimensional stability across the disc rotor directly achieved by the individually spaced pillars and columns.
These advantages increase the disc rotor's efficiency by as much as 20% when compared to conventional rotor designs. A 20% increase in disc rotor efficiency directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder.
All 4000 series rotors also benefit from DBA's "Longlife Slotted" design. The rotors are manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix resulting in long wear and safe, consistent stopping power.
- Unidirectional slotting (left and right) increases pad bite, reduces fade and delivers exceptional braking performance.
- Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring.
- Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
- Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt.
- Slotting also combats "out-gassing," where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power.
DBA rotors are chosen as Original Equipment on many vehicles.
Los discos de frenos de la serie 4000 Wiper-Slot fabricados por Disc Brakes Australia (DBA, por sus siglas en inglés), poseen un diseño único de ranuras 6x6 que proporcionan un poder extremo de frenado en carreteras y competencias. Como todos los discos de frenos DBA, la serie 4000 se ajusta al vehículo sin necesidad de cambios mecánicos.
La serie media de discos de freno DBA mejora el rendimiento considerablemente y los frenos de discos con ranuras utilizan la tecnología: Perfil de Estabilidad Térmica (Thermal Stability Profiling, TSP por sus siglas en inglés), para mejorar la administración de calor. Las marcas de pintura Thermo-Graphic ayudan a monitorear el calor.
TSP es un proceso único desarrollado por DBA para mejorar el rendimiento de los discos de frenos, algunos de sus beneficios incluyen:
- Aumentar la resistencia a la fatiga del disco, causada por el calor.
- Reducir la fatiga del disco, durante períodos de frenado continuo.
- Son fáciles de reemplazar, con un tiempo mínimo de adaptación.

Las marcas de pintura Thermo-Graphic se encuentran ubicadas, en el borde exterior de todos los frenos de discos DBA de la serie 4000 y monitorean las temperaturas centrales alcanzadas durante el frenado. Las marcas cambian de color a medida que la temperatura del freno de disco excede los niveles óptimos.
Color Original | Cuando el disco excede esta temperatura: | El color cambiará a: |
| | 458°C | |
| | 550°C | |

"Kangaroo Paw" es un sistema de ventilación de tecnología avanzada, para frenos de discos, diseñada y fabricada en Australia por Disc Brakes Australia, y se puede obtener para marcas selectas de autos. La tecnología "Kangaroo Paw" ofrece un significativo avance en rendimiento de frenado. Inclusive, durante un frenado continuo, la tecnología "Kangaroo Paw", se encarga de mantener la temperatura del disco más fría. Además los discos de frenos DBA son más fuertes y sobrepasan el rendimiento de los discos tradicionales con ventilación directa.

El diseño "Kangaroo Paw" posee columnas entre las caras del disco y 144 pilares individualmente espaciados, en forma de diamantes y lágrimas.
Este sistema ofrece dos ventajas importantes.
Primero, la habilidad de enfriar el freno de disco más rápido, como nunca antes se había logrado. A medida que el disco rota, se crea una turbulencia aerodinámica alrededor de los pilares y las columnas, la cual, aumenta la fuerza para ventilar el aire caliente desde el centro hacia fuera del disco.
Segundo, mayor estabilidad dimensional en todo el disco, alcanzada directamente por los pilares y columnas espaciadas individualmente.
Estas ventajas aumentan la eficiencia del disco en un 20% más que los diseños de discos convencionales. La eficiencia de este sistema se evidencia: en una temperatura más baja de operación al frenar, en la reducción del debilitamiento del frenado causado por el calor, la disminución de la tensión del disco de freno, la disminución de la variación de espesor y la reducción de vibración al frenar.
La serie 4000, además, se beneficia del diseño de las ranuras de larga vida Longlife Slotted. Los frenos de discos son fabricados bajo los estándares de calidad QS-9000, utilizando materiales con grado Premium con alto contenido de hierro y una matriz densa de metal. Estas características, dan como resultado un poder de frenado seguro, duradero y consistente.
- Ranuras unidireccional (izquierda y derecha) aumenta la mordida de la pastilla, reduce la tendencia del frenado a debilitarse por el calor y ofrece un excepcional rendimiento al momento de frenar.
- Las ranuras eliminan el esmalte de las pastillas de frenos continuamente mejorando la eficiencia y disminuyendo rayones en el disco.
- Las ranuras hacen que el desgaste sea igual en la superficie de las pastillas, mejorando la efectividad del área de contacto, a la vez de, extender la vida del disco de frenos.
- Al manejar en climas malos las ranuras ayudan a disipar el agua, al mismo tiempo sacan polvo y sucio del freno de disco.
- Las ranuras ayudan a combatir el efecto de gas (cuando los agentes de fricción de las pastillas forman una capa entre la pastilla y el disco, reduciendo grandemente el poder del frenado).
Los discos de frenos DBA son escogidos como discos de Equipo Original (Original Equipment) para muchas marcas de vehículos.

Great products so far and my expectations have been exceeded. Poor reviews on the Tire rack web site but other web sites provide many positive reviews of this brake combo. That led to my decision to buy.

The DBA rotors are of exceptional quality. I purchased the 4000XS model. In my brake system conversion they stop well in daily driving and show no fade when braking heavy from 150+ MPH to 40 MPH with average repeated use. For those of you using these on the track, they are intended for normal/heavy street use, not track. If you want true track rotors upgrade to the 5000 series and stop playing games. Consider the weight of your vehicle as well. Mine is nearly 5000 lbs. and the 4000 series rotors have stood up well without any cracking or overheating. Larger vehicles, such as trucks, may want to look into the 5000 series as well which will also help prolong the life of your bearings, a common failure on many models. In addition, anyone complaining of warping or brake shimmy your rotors were not installed properly. These rotors DO NOT WARP. The shimmy you get is from high and low spots on the rotor caused by uneven friction material transfer, especially when using ceramic formulations. This occurs when the rotors have excessive lateral runout (wobble), which may be as little as a few thousandths of an inch. You MUST clean your hub mounting surface for the rotor hat with a wire wheel or other device to remove rust and other debris, check the inside of the hat for uneven paint (if painted) and check for lateral runout with the rotor installed using the wheel lugs and proper torque specifications. If you do not follow these procedures and properly torque your wheels after installation the problems you are having are caused by YOUR FAILURE as a mechanic and not an inferior product. I ve seen people put new OE rotors and pads on a car without checking and have a pulsation in 3000 miles.
