Wilwood Red AERO6 Front Brake Upgrade for Early F-100 Drum Spindles, 14-Inch SRP Rotors and Aluminum Hubs

This Wilwood AERO6 kit is a front 14-inch AERO6 hub upgrade for 1957–1967 F-100 Trucks with Factory Drum Spindles. AERO6 calipers use 14 x 1.25-inch rotors on separate aluminum hubs and hats for the verified early F-100 spindle. 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.

Technical Details

• Manufacturer part number: 140-14839-DR.
• The specified radial caliper is an AERO6. It combines a Red Powder Coat forged aluminum body with 6 pistons per unit; the published piston material is stainless.
• When planning the line connection, account for the 1/8-27 NPT caliper inlet.
• Bores and friction material: 1.62, 1.12, 1.12 inches, with BP-10 pads supplied for the specified calipers.
• The vented discs have srp drilled & slotted friction surfaces and Spec-37 Iron construction. Nominal dimensions are 1.25 in; 31.75 mm through the braking section and 14.00 in; 355.6 mm at the outside edge.
• Aluminum hats with Black E-Coat finish complete the two-piece rotor assembly.
• The wheel-stud thread is 1/2-20; the matching wheel mounting pattern(s) are 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm. These describe different aspects of the attachment.
• Included wheel hubs use aluminum construction and the listed threaded-stud arrangement. They are separate from the friction discs.
• The supplied hardware mounts the specified brake package. It does not include replacement spindles, a brake booster or a master cylinder.
• Flexlines are excluded from the brake package. Select the chassis-specific hoses and confirm safe clearance throughout travel. Separate reference: 220-11237.
• The caliper package calls for at least the published 18 in; 457.2 mm wheel diameter, plus sufficient spoke and inner-barrel clearance.
• This is a kit listing; one package contains the brake components described above.

Fitment & Compatibility

Match the original drum-spindle arrangement and exact listed year/drive rows; 1959–1967 specifies 4 x 2. DS-1265 covers the hub bearings and radial brackets. Wheels must match 5 x 4.50 or 5 x 4.75-inch hubs and pass the clearance drawing; 5 x 5.50-inch wheels are not supported by these hubs. Models covered: F-100. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

PMB Performance has more than 20 years of experience with parts and fitment. We can help review the specified kit against your vehicle's actual spindle, axle or existing brake components and wheel-clearance information.

Manufacturer Warning

Applicable to the included brake pads only: Wilwood warns of exposure to arsenic, cadmium, hexavalent chromium compounds, lead, nickel, cobalt and antimony trioxide, chemicals known to California to cause cancer or reproductive harm. More information: www.P65Warnings.ca.gov.
