HPS 5.0 Disc Brake Pads

The Hawk Performance HB621B.638 HPS 5.0 High Performance Street disc brake pads are engineered to significantly enhance the braking capabilities of your street-legal vehicle. These pads utilize Hawk Performance's proprietary HPS braking compound, which provides a higher coefficient of friction compared to standard brake pads. This results in a substantial increase in stopping power, estimated between 20 to 40 percent, along with improved resistance to brake fade during demanding driving conditions. The HPS compound is formulated to offer a more consistent pedal feel and predictable performance, even under high temperatures, while also reducing brake dust for cleaner wheels. All Hawk Performance brake pads are manufactured in ISO certified facilities and are free from asbestos, lead, chromium, cadmium, and antimony. To guarantee their effectiveness, Hawk Performance subjects their brake pads and rotors to extensive testing, including dynamometer simulations that mimic real-world driving scenarios from professional racetracks to everyday street use. On-vehicle testing is also conducted to ensure each product meets stringent performance criteria before market release. These specific HB621B.638 pads are designed as rear brake pads for the following BMW models and years: 2008-2013 BMW 128i Base, 2007-2013 BMW 328i Base, 2009-2013 BMW 328i xDrive Base, 2007-2008 BMW 328xi Base, 2013-2015 BMW X1 sDrive28i, 2012-2015 BMW X1 xDrive28i, and 2013, 2015 BMW X1 xDrive35i.
