Wilwood Plain-Rotor Front Brakes with Red Dynalite Calipers, Cadillac Series 75/Series 67/Eldorado/Series 63/DeVille/Series 62/Series 60 Fleetwood/Series 61/Series 75 Fleetwood/Series 60/Series 60 Special Fleetwood/Commercial Chassis (1941–1955)

Plain-face 11.75-inch rotors and red Dynalite calipers identify this Wilwood front hub package for the stated Cadillac drum-spindle applications. The conversion includes four-piston calipers, replacement hubs, bearing components and dedicated mounting brackets. It must match the car's actual spindle and exact series/year entry, particularly where earlier modifications have changed the original front brake arrangement. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Technical Details

• Type: Forged Dynalite Pro Series Front Brake Kit
• Calipers: Forged Dynalite Internal; 4 pistons per caliper; Red Powder Coat.
• Caliper bore sizes: 1.75, 1.75 inches. Piston type: Stainless.
• Included pad compound: BP-10.
• Rotors: 11.75-inch diameter × 0.81-inch thickness; Plain Face; Iron; Plain surface; 32 vanes.
• Wheel mounting change from OE: +0.35 inches per side.
• Replacement hubs: Hub - Vented Rotor Offset; Aluminum; Bare.
• Wheel bolt circles: 5 x 5.00 inches.
• Included: paired calipers, pads, rotors, mounting brackets and assembly hardware, replacement hubs.
• Hydraulic lines and fittings selected separately. No master cylinder, booster or spindles are supplied.
• Conditional wheel screening size: 15 inches. Use the installation clearance diagram to verify the actual barrel and spoke profile.
• Wheel-contact support requirement: if the wheel contact surface overhangs the hub face, use the specified 6.60-inch-diameter × 0.20-inch-thick steel spacer between hub and wheel. The spacer is supplied with this kit.
• The wheel-clearance drawing includes the supplied wheel spacer installed; account for its thickness and stud engagement in the completed wheel arrangement.
• For stamped steel wheels whose contact area does not overhang the hub, Wilwood recommends the separate 6.15-inch-diameter × 0.09-inch-thick hub shield to protect the hub face; this is distinct from the required overhang-support spacer.

Fitment & Compatibility

Use DS941 to confirm mounting geometry and bearing fit. The hub increases wheel position by 0.35 inches per side, which affects body clearance independently of caliper clearance. Verify wheel bolt pattern, stud engagement and the actual spoke/barrel envelope before ordering hydraulic hoses. The master-cylinder and pedal arrangement must provide appropriate volume and travel, with front/rear balance checked after the brake conversion is assembled.

Match the individual model, year, submodel and brake configuration in the fitment table below.
