Wilwood SRP Front Brakes with Black Dynalite Calipers, Oldsmobile Series 76/Series 78/Series 96/Series 98/E-47/F-47/G-47/J-47/L-47/Series 88/88/98/Deluxe 88/Standard 88/Super 88/Series 60/Series 70/Series 90/Series 66/Series 68 (1940–1952)

Black Dynalite calipers and drilled/slotted 11.75-inch rotor rings identify this Wilwood front package for the listed Oldsmobile drum-spindle applications. Replacement hubs, bearings and brackets establish the mounting, with the selected four-piston calipers using BP-10 pads. The car's exact series and spindle must be checked, particularly if earlier chassis work has changed the original brake hardware. 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.

• 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

DS936 supplies the installation and wheel-envelope dimensions. Confirm the five-on-five-inch wheel pattern and bearing seating before assessing the positive 0.039-inch hub offset change. The 15-inch screening figure still requires spoke and barrel checks. Select suitable hydraulic hoses separately and inspect the master-cylinder pushrod layout for any required adaptation. Correct pedal travel and front/rear hydraulic balance are part of the completed conversion.

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