Brand: Wilwood Engineering
Wilwood pad shape 7816 fits Wilwood Dynapro and NDL (Narrow Dynalite) 4-piston calipers using a central bridge bolt or two retaining pins. Not for older calipers that only use a central retaining pin. 0.60" (15.2mm) overall thickness including backing plate.
This pad has the same dimensions as the original Wilwood 7216 / Hawk HB237 / PFC 7754 pad shape for the Wilwood Dynalite Bridge Bolt caliper (also called out on the spec sheet for the Narrow Dynalite), but with raised corners instead of two central tabs straddling the bridge bolt. Note that the original 7216 pad shape is no longer offered by Wilwood. This 7816 shape is the recommended replacement.
A - PolyMatrix A has the highest friction (hot and cold) of any Wilwood racing compound. The low wear rate and extremely high temperature range makes it suitable for endurance racing in the most severe applications. The quick low-temperature response makes PolyMatrix A very flexible. Higher friction than all other Wilwood compounds from 200°F to 1000°F (tied for first with PolyMatrix H from 800°F to 1000°F). Peak friction is available between 300°F and 800°F.
