Hawk HB540W.490 DTC-30 Race Brake Pads for Wilwood Dynalite BDL FDL Caliper

Vehicle Fitment

This is a universal racing caliper brake pad. It is not vehicle-specific and is not sold for use with OEM stock calipers. Fitment is determined by caliper model. Compatible racing calipers include:

• Wilwood Billet Dynalite (BDL) - cotter pin retainer version (Wilwood pad shape 7112)
• Wilwood Forged Dynalite (FDL) - cotter pin retainer version (Wilwood pad shape 7112)

Fitment Notes

• This pad is universal for racing calipers - it is not designed for OEM stock brake calipers and has no vehicle-specific fitment.
• This pad fits only the cotter pin retainer versions of the Wilwood Dynalite caliper family. It is not compatible with Bridge Bolt versions of the Wilwood Dynalite or Superlite calipers, which require a different pad shape (HB521 series).
• This pad has the same dimensions as the classic Hawk HB100 pad and is fully interchangeable with it in the Wilwood 4-piston Dynalite caliper. The HB540 differs only in having some non-critical material removed from the backing plate.
• Wilwood pad shape reference: 7112.
• Not compatible with carbon ceramic rotors. For use with iron/metal rotors only.
• DTC-30 is a motorsport compound. While it operates effectively from cold and has been used on street-driven vehicles where braking performance is the priority, it is a race-classification compound that produces more dust and noise than street compounds. It is not suited for comfortable daily driving.
• DTC-30 is frequently used on the rear axle of lighter race vehicles paired with DTC-60 at the front, and on both axles in dirt track, gravel rally, and drag racing applications where cold effectiveness and smooth engagement are prioritized over maximum peak torque.
• Sold as a set of 4 pads (one axle / two calipers). For a full front-and-rear race brake upgrade, two sets are required.

Features

• DTC-30 Ferro-Carbon compound - Hawk's controllable-torque, multi-purpose motorsport formulation delivering smooth consistent feel and bite across a wide temperature range through the Wilwood BDL and FDL calipers, proven in dirt track, gravel rally, drag racing, autocross, and circuit racing applications where excellent cold effectiveness and smooth, manageable pedal feel are prioritized over maximum peak deceleration force.
• Excellent cold effectiveness - Provides strong, consistent brake torque through the Wilwood Dynalite calipers from ambient temperature without any warm-up cycle, making DTC-30 the preferred compound for autocross competition, drag racing, and short-format circuit events where pads remain cold at the start of each run.
• Controllable, predictable medium torque - The DTC-30's signature characteristic in the Wilwood BDL and FDL calipers is its smooth, manageable torque output, giving drivers the precision to modulate brake pressure and achieve clean caliper release without the abrupt engagement of higher-torque DTC compounds - essential for applications such as dirt track and gravel rally where controlled, progressive brake application is more important than maximum braking force.
• Superior release characteristics - Delivers clean, linear brake release through each Dynalite caliper application, supporting stable handling balance, neutral corner exit behavior, and smooth power application across all motorsport disciplines where the Wilwood Dynalite system is used.
• Very low rotor wear - Produces significantly lower abrasive rotor wear than DTC-60 and DTC-70, extending disc service life across competitive seasons and multi-event schedules - an important advantage for teams running premium rotors in conjunction with Wilwood Dynalite caliper systems.
• Wide operating temperature range - 100-1,200°F total range with a 100-800°F optimal window, providing consistent performance from cold ambient through sustained high-load racing temperatures across dirt track, rally, autocross, and circuit applications - the broadest effective range of any compound available for the HB540 shape.
• Multi-purpose motorsport versatility - Proven and recommended for dirt circle track, gravel rally, NASCAR modified, drag racing, trophy trucks, pro buggies, and road course applications through Wilwood Dynalite calipers where controllable torque and cold effectiveness are more valuable than maximum peak deceleration.
• Effective as both a front and rear compound - On lighter platforms running Wilwood Dynalite calipers, DTC-30 works well on both axles. In split-friction setups, it is the natural rear compound paired with DTC-60 at the front to bias braking torque forward while keeping rear engagement smooth and predictable.
• 100% asbestos, lead, chromium, cadmium, and antimony free - Manufactured in an ISO-certified facility to strict quality and environmental standards.

Product Description

The Hawk HB540W.490 DTC-30 brake pads bring Hawk's controllable-torque multi-purpose motorsport compound to the Wilwood Billet Dynalite (BDL) and Forged Dynalite (FDL) calipers with cotter pin retention, using Wilwood's 7112 pad shape. As with all HB540-series pads, this is a cotter pin-only fitment - Bridge Bolt versions of the Wilwood Dynalite and Superlite families use the HB521 shape instead. The HB540 shape is dimensionally identical to the classic Hawk HB100 pad and is fully interchangeable with it in the Wilwood 4-piston Dynalite caliper.

DTC-30 is the most versatile compound available for the HB540 shape, operating across a 100-1,200°F range starting from ambient cold - wider than any other compound in the HB540 lineup. This broad effective range makes it the standard choice for applications where brake temperatures vary widely or where cold effectiveness cannot be sacrificed: autocross events where each run starts from a cold pad state, drag racing where brakes must work immediately from launch, and dirt track or gravel rally applications where the compound's smooth, controllable engagement characteristics are specifically optimized for low-grip surface conditions. The DTC-30's very low rotor wear also extends disc service intervals across competitive seasons, making it cost-effective for teams competing in multiple events throughout the year with Wilwood Dynalite systems.

DTC-30 is a motorsport-classification compound. While it has been used successfully on street-driven performance cars where braking is the primary concern, it is not suited for quiet daily driving. Sold as a set of 4 pads covering one axle and two calipers. A second set is required for a complete front-and-rear race brake upgrade. Compatible with iron and metal rotors only; carbon ceramic brake discs are not supported.
