The Hawk Performance HB105F.620 is an HPS (High Performance Street) disc brake pad set sold for Alcon B-type calipers. The manufacturer says its HPS compound gives a higher friction coefficient than stock pads, with 20-40% more stopping power and better resistance to brake fade. It also says the compound produces less dust than original pads and is gentle on rotors. For a canyon-driven sport car or a weekend track-day machine that still gets daily driving, that means firmer, more consistent stops at a lower cost than many big-brake upgrades. Compared with a budget aftermarket pad, the HPS compound is built for repeated hard stops, not just light street use.
Check fitment before ordering. The part number and product name point to an Alcon B-type caliper application, so confirm the match with the manufacturer. The manufacturer's street bedding procedure calls for 6 to 10 moderate stops from 30 to 35 MPH, then 2 to 3 hard stops from 40 to 45 MPH, with no dragging and at least 15 minutes of cool-down. Hawk also states its compounds are not compatible with carbon ceramic rotors, so use these pads on iron rotors only. Keep the pads and rotors clean, and check the disc for thickness, runout, and scoring deeper than .012 inch.
Yes. The manufacturer's street procedure calls for 6 to 10 moderate stops from about 30 to 35 MPH, followed by 2 to 3 hard stops from about 40 to 45 MPH, with a cool-down period before normal use.
No. The manufacturer states its compounds are not compatible with carbon ceramic rotors and that its pads are designed for iron or metal rotors.
The manufacturer recommends installing the pads securely, bedding them in properly, washing and drying the rotor, turning or machining the rotors if needed, and applying a thin layer of silicone anti-squeal lube to the back of the pads.
The manufacturer says pads should be installed according to the vehicle manufacturer's application-specific instructions, with the pad securely seated in the caliper. Before fitting the new pads, flush the system with fresh brake fluid and check all hydraulic parts for wear. Verify that the caliper moves freely and lubricate where necessary. Sand the discs with garnet sandpaper at moderate pressure, clean them with soap and water, and make sure they are free of oil, grease, and brake fluid. Do not reuse badly worn or damaged rotors with new pads. Once the pads are installed, follow the bedding procedure above and avoid dragging the brakes during break-in.
