BMW HP Plus Brake Pad Set - Hawk HB624N.642

The Hawk Performance HP Plus brake pad compound is ideal for Autocross and Track Day drivers looking for a high performance race compound that can take the heat of the track and get you home safely without having to change the pads. HP Plus utilizes a unique Ferro-Carbon, High-Tech friction material that was developed and manufactured for sport driving in autocross, Solo II, and track day applications. The Ferro-Carbon formulation offers lower wear rates and higher torque values than other competitive materials.

• Low to mid temperature range
• Fade resistant
• Smooth & predictable torque
• Ideal for Autocross
• All Hawk Performance compounds are not compatible with carbon ceramic rotors. Hawk pads are designed to work with Iron/Metal rotors.
• 100-800 F operating temperatures
• 300-600 F optimal temperature range

Bed in instructions:
1. After reaching medium speed engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat four or five times.
2. At higher speeds engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat five times.
3. At or near race speed engage brake pedal to slow car without coming to a complete stop. Release pedal quickly and do not drag brakes. Repeat three times. Allow a few seconds between brake engagements while car is in motion.
4. Do not hold brake pedal. Park car for approximately 20 minutes or until brake rotors are completely cool to the touch.
5. If during the above steps the brake pedal becomes soft or brake fade is noticed, park the car immediately for approximately 20 minutes. Do not hold brake pedal.

IMPORTANT REMINDERS WHEN BURNISHING/BEDDING BRAKE PADS

• Do not attempt to use badly worn or damaged rotors with new brake pads.
• Do not drag brakes while car is moving during break-in procedure.
• Do not engage pedal while car is stopped at any time following the break-in procedure.
• Upon completing the procedure, allow the brake system to completely cool before racing.
• Applying the pedal a few times before the start of the race will allow the brake pads to heat up before attempting to reach race speeds.
• Clean a used rotor surface with fine sand paper or steel wool, rinse with water, dry and install before bedding new pads.
• Some forms of racing don�t allow time for the proper break-in procedure to be performed. However, it is still very important to attempt to perform at least the core of the procedure: Build up heat slowly and allow the system to completely cool down before racing if possible.
