Product details

This staggered rear brake conversion combines four-piston Dynapro Low-Profile service calipers with 11.00-inch rotors and internal drum parking-brake assemblies. Red calipers and 11.00-inch SRP drilled & slotted rotors are the selected configuration. The axle interface is the BOP 2.75-inch bearing flange with a 2.75-inch axle offset. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems, with selection governed by the complete brake installation.

Technical Details

  • Product identification: Wilwood 140-16988-DR. Package quantity: one kit for the stated configuration.
  • The brake package includes pads and required mounting hardware, excluding spindles, master cylinder and booster.
  • Drum parking-brake assemblies are included inside the rotor hats. Supply parking cables, cable hardware/adapters and hydraulic hoses/fittings separately.
  • Hydraulic line selection is a separate purchase. Check hose length, adapters and routing before assembly.
  • Check the wheel-clearance diagram before purchase; the nominal minimum wheel diameter is 14 inches.
  • Connect the hydraulic line through the 1/8-27 NPT caliper inlet.
  • This assembly leaves the documented wheel hubs in use. It supplies brake components rather than new hubs.
  • Piston sizing follows the published 1.38, 1.38-inch specification. The included brake-pad compound is BP-10.
  • Caliper selection is 4-piston Forged Dynapro Low Profile. Body finish: red powder coat; attachment: lug; piston material: stainless.
  • Rotor package uses SRP Drilled Rotor & Hat components. Each is 0.81 inch thick with 11.00-inch diameter and SRP drilled & slotted faces. Published material: Iron.

Fitment & Compatibility

Use measured axle dimensions: BOP 2.75-inch bearing flange, 2.75-inch offset and the staggered shock/caliper layout. DS-1529 describes the 1964–1970 Buick/Oldsmobile/Pontiac axle arrangement, but no particular vehicle model is established here. Confirm the flange drawing, rotor register and axle-flange maximum of 6.61 inches with the specified chamfer. The rotor hat is drilled for 1/2-inch wheel studs; upgrading smaller studs may require machining. Hydraulic hoses/fittings and parking cables, hardware or adapters are not supplied.

With over 20 years of parts and application experience, PMB Performance can help compare this assembly with your existing brakes. Supply the hub, axle or spindle specification and wheel-clearance information before ordering.
