Wilwood Anodized Dynalite-M Front Kit with Drilled Rotor/Hubs for Selected Mercury Comet/Cougar/Montego/Cyclone and Ford Fairlane/Falcon/Maverick/Mustang/Ranchero/Torino (1970–1974)

The SRP rotor configuration adds directional drilling and slots to this later-spindle Dynalite-M front conversion. Calipers remain anodized, and each iron rotor incorporates its wheel hub; the required wheel bearings, bracket hardware and flexible lines are part of the kit installation. For this conversion, component matching remains essential. Its manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems for motorsport, street-performance and specialized applications; its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines selected to work within a complete system.

Technical Details

• Calipers: 4 stainless pistons per caliper; lug mounting; forged aluminium bodies. Color: Anodize. Finish: Type III Anodize. Inlet thread: 1/8-27 NPT.
• Caliper family: Forged Dynalite-M. Brake-pad compound: BP-10.

• Manufacturer: Wilwood; manufacturer part number: 140-13477-D. Supplied quantity: Sold as a kit.
• Application category: Front Brake Kits - Street Performance. Axle/spindle category: Front Kits. Brake function: Disc.
• Hubs are integral with the one-piece iron rotor castings. No separate hub assemblies are supplied; the rotor/hubs include the wheel-hub function.
• Mounting hardware included: Yes. Spindles included: No. Master cylinder included: No. Brake booster included: No.
• Flexible brake lines included: Yes; matched line kit 220-9195, 18.00 inches nominal length.

• Rotor: 11.29 in; 286.77 mm outside diameter; 0.94 in; 23.88 mm thickness. Material: Iron. Construction: Vented. Friction-face style: SRP Drilled & Slotted.
• Rotor surface finish: Black Electro Coat.

• Wheel interface: 5 X 4.5 in; 5 X 114.3 mm. Wheel-stud specification: 0.50 in; 12.70 mm.
• Nominal minimum wheel diameter: 14 in; 355.6 mm. Verify the full wheel-clearance drawing; diameter alone does not establish barrel or spoke clearance.

Fitment & Compatibility

Verify the retained factory drum or disc spindle against the full application table. The later Falcon/Maverick production split and Mustang Shelby exclusion distinguish this group from the early-spindle kit. Drum-brake wheels are unsuitable even when their nominal diameter is 14 inches.

A master-cylinder change can require modification of the existing pushrod assembly. The separate universal parking-cable note applies only if the rear brakes are also being converted; this front kit does not supply a rear parking-brake conversion.

Where a different chassis connection or length is needed, universal flexline references are 220-7056 (14 inches), 220-7699 (16 inches) and 220-8307 (18 inches). These are alternatives to assess, not additional sets included in the kit.
