{"product_id":"wilwood-140-14421-d","title":"Wilwood Front Dynapro Drag Brake Kit for Listed Camaro \u0026 Firebird Single-Piston-Caliper Spindles, Drilled Rotors","description":"\u003cp\u003eReplace the specified Camaro or Firebird front brake assembly with a five-lug Dynapro drag system. Drilled solid steel rotors attach through dynamic adapters, while the four-piston calipers use BP-20 pads and stainless pistons. The kit includes hubs, wheel bearings, seals and extended studs. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake systems and components. Its motorsport, street-performance and specialized range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines, with compatibility assessed across the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-14421-D.\u003c\/li\u003e\n\u003cli\u003eMatch the Dynapro caliper architecture when selecting related components: lug attachment, 4 stainless pistons, forged aluminum body and Type III Anodize finish.\u003c\/li\u003e\n\u003cli\u003ePad selection is BP-20; piston-bore measurements are 1.75, 1.75 inches.

The new caliper is four-piston; the single-piston wording describes the required original spindle. Modify that spindle only as the installation instructions direct. Match the model year and existing rear-disc or rear-drum configuration below and observe the corresponding vehicle-weight limit. Hoses are not included; select a compatible line kit for the chassis. Check final wheel position and the brake-clearance template before buying five-lug wheels for the conversion. Models covered: Camaro and Firebird. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.\u003c\/p\u003e\u003cp\u003eFront Brake kits fit OE Single piston caliper spindles only.\u003c\/p\u003e\u003cp\u003eRequires modifications to original spindle\u003c\/p\u003e\u003cp\u003eKit may fit some 14\" wheels.

Wheel contact surfaces must sit fully on the hub: use separately ordered spacer 300-11961 when they overhang the hub face. For stamped-steel wheels that stay within the hub face, Wilwood specifies shield 300-10716. Verify all wheel contact and clearance requirements in the instructions.\u003c\/p\u003e\u003cp\u003eFor fitment assistance, provide PMB Performance with the existing brake configuration and measured mounting\/wheel details.
