The Hawk HB110Z.654 is a Performance Ceramic (PC) street pad with a 0.654-inch friction thickness, sold as the AP CP5200 caliper version. The manufacturer's listing presents it as extremely quiet and ultra-low dust, with improved stopping power and a stable friction output. Hawk designs these pads for iron or metal rotors, so confirm your disc material before you order. Stock pads rarely offer this level of dust control, and this is the reason to pay for it: clean wheels and quiet stops on a street-driven performance car. Buyers wanting maximum bite should look elsewhere. If you autocross or track once in a while, owners suggest stepping up to a more aggressive Hawk compound instead. Owners on user forums describe the ceramic as a dust-reduction upgrade, with the performance gains intended to roughly match stock-level stopping power.
Search terms this pad answers include AP CP5200 ceramic street brake pads, HB110Z.654 install, low dust AP Racing caliper pads, and Hawk PC ceramic bedding procedure. Expect some noise variation. One owner on a BMW forum described squeal at the end of each stop on a different vehicle, and owners on user forums recommend a heat-resistant copper-based brake paste on the pad backing plate and where the pad contacts the caliper.
No. The manufacturer states that its Performance Ceramic compound is not compatible with carbon ceramic rotors and is designed for iron or metal rotors.
Yes. The manufacturer recommends a street bed-in of 6 to 10 stops from roughly 30 to 35 mph at moderate pressure, followed by 2 to 3 harder stops from 40 to 45 mph, then a 15-minute cool-down without dragging the brakes.
Owners on user forums report that squeal varies between installs and vehicles. Those owners generally attribute it to missing or incorrect lubrication on the pad backing plates and caliper sliding surfaces, and they recommend applying Hawk's caliper grease at those contact points.
The manufacturer's install guidance calls for turning or machining the rotors, washing and drying them, installing the pads securely, and then bedding them in. Because AP Racing's kit manual covers CP5100 and CP5200 calipers, check that the anti-rattle clips are fitted with the arrow matching disc rotation and that they do not touch the disc. The same manual gives a pad retaining bolt or pin torque of 14 Nm (10 lb-ft), though that figure applies to its kit systems, so verify it for your setup. Check the brake fluid level, and confirm that the hoses are routed correctly. Because AP Racing defers to the pad manufacturer's instructions for OE-type pads, follow Hawk's bed-in procedure rather than a generic one.
