Race Compound Friction Built for AP Racing and Alcon Calipers
The Hawk Performance HAWKHB109G.980 brake pad is a DTC-60 compound pad measuring 0.980 inches in thickness, engineered to work with AP Racing and Alcon 4 and 6-piston calipers that accept a pad of this radial depth. DTC-60 is a medium-to-high temperature race compound rated from 100 to 750 degrees Celsius (200 to 1,400 degrees Fahrenheit), making HAWKHB109G.980 appropriate for track days, endurance racing, and high-performance driving events where organic street pads overheat and fade. The friction coefficient is 0.52 Mu, which is well above street-spec compounds, delivering consistent and progressive pedal feel throughout a full brake zone. This compound also bites cold enough to be used during warm-up laps, so it does not require extensive bedding heat cycles before it reaches effective operating temperature. The pad backing plate carries Hawk’s proprietary bonding process, which prevents delamination under the thermal cycling that race use creates.

FAQ
What is the HAWKHB109G.980?
The HAWKHB109G.980 is a Hawk Performance DTC-60 race brake pad (Hawk Part No. HB109G.980) measuring 0.980 inches thick, designed for AP Racing and Alcon calipers that accept this pad dimension, with a 0.52 Mu friction coefficient and a 100 to 750 degree Celsius operating range.
What vehicles does this pad fit?
This is a universal pad sized by caliper application rather than vehicle make and model. It fits AP Racing and Alcon 4 and 6-piston calipers that use a pad with a 0.980 inch radial depth. Confirm your caliper model and pad dimensions against the Hawk fitment guide before ordering.
Is the DTC-60 compound safe for street driving?
DTC-60 is rated for street use but is optimized for track temperatures. It produces more dust and noise than street compounds, and it requires the rotor to reach operating temperature to deliver its peak friction coefficient, so it is best suited for dedicated track-day or race use.
What is the minimum temperature this pad needs to reach full friction?
DTC-60 is effective from approximately 100 degrees Celsius, which means it generates useful friction within the first few brake applications, making it suitable from the start of a session without a prolonged warm-up procedure.
What rotors are compatible with DTC-60 compound pads?
DTC-60 pads are compatible with both solid and vented steel or cast iron rotors. For track use, Hawk recommends vented rotors to allow adequate heat dissipation during repeated hard braking.
How do I bed in these pads?
Perform 8 to 10 progressively harder stops from approximately 60 mph down to 10 mph without coming to a complete stop. Allow a cooling period between cycles. Avoid holding the brake pedal stationary on a hot rotor to prevent pad material transfer spotting.
Can these pads be used with ABS-equipped vehicles on track?
Yes. DTC-60 compound pads work with ABS systems. The higher friction coefficient may alter ABS activation threshold slightly compared to street pads, which is normal for race compound friction material.
What is the shelf life of unused DTC-60 brake pads?
Unused pads stored in a cool and dry environment away from moisture and direct sunlight maintain full performance characteristics for several years. Inspect pads for signs of contamination or surface glazing before installation if stored for extended periods.
Install Instructions
- Lift and support the vehicle safely on jack stands and remove the wheels.
- Remove the caliper from the rotor carrier without disconnecting the brake line, and suspend it to avoid stress on the brake hose.
- Remove the worn pads from the caliper bracket and clean all pad contact surfaces with brake cleaner.
- Inspect the rotor for minimum thickness, heat cracks, and scoring. Replace if below minimum spec.
- Retract caliper pistons using a proper piston retraction tool, being careful not to damage piston boots.
- Apply a thin layer of high-temperature brake lubricant to pad ears and caliper abutment surfaces only. Keep lubricant off friction material and rotor faces.
- Install the new HAWKHB109G.980 pads into the caliper bracket.
- Reinstall the caliper and torque bolts to specification.
- Pump the brake pedal until firm before moving the vehicle.
- Perform the bedding procedure described above before entering high-load braking zones.
