Brake Caliper, Narrow-Mount Dynalite, Aluminum, Gray Anodized, 4-piston, Wilwood Logo, 1/8 in. NPT, Each
Wilwood narrow-mount Dynalite brake calipers, or NDL's, feature an FEA-generated radial transition design that eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. This design substantially increases resistance to deflection and caliper separation under severe loads. These narrow-mount Dynalite brake calipers are equipped with Wilwood's SRS stainless steel bridge wear plates, which are designed to eliminate bridge wear caused by pad gouging and extend the service life of the caliper. Internal fluid passages get rid of the need for external tubes. Four-corner bleed screws ensure simple and effective air evacuation from the system. Their high-luster Type III Mil-Spec hard anodized finish, stainless steel pistons, and high-temperature seals make Wilwood narrow-mount Dynalite brake calipers the perfect choice for your late model, modified, Sprint, off-road, or road-racing vehicle. Order the model designed for your vehicle's application.
