Narrow DynaPro calipers use type 7812 pads that are supported from the top by Quick-Clip pad retainers. Quick-Clips allow fast access to the pads for service without the need to dismount the caliper. The Quick-Clip design also allows additional inside radial clearance between the caliper body and the lug hub by eliminating the bottom pad support feet found on other caliper models. Side inlet DynaPros use additionally fortified bridge bolts in place of the Quick-Clips for the ultimate in secure pad retention within high load environments on sprint cars and other extreme duty applications.
The DynaPro incorporates other exclusive Wilwood performance enhancements. Stainless SRS bridge plates eliminate caliper bridge wear from pad gouging while dampening noise and vibration during engagement. Internal fluid passages eliminate the need for external crossover tubes and four corner bleed screws allow effective gas evacuation regardless of mounting location.
