Wilwood Forged Dynalite Big Brake FDLI Pro-Series Park Brake Kit for 58-64 Olds/Pontiac Ends

The Wilwood Forged Dynalite Big Brake FDLI Pro-Series Park Brake Kit (Part #140-7147) is designed as a high-performance rear disc brake upgrade for 1958–1964 Oldsmobile and Pontiac models with 2.81-inch axle offset. This kit includes forged Dynalite four-piston calipers (available in black, red, or polished finishes), 12.19-inch vented rotors, and high-friction brake pads for improved stopping power, heat dissipation, and pedal response. An internal shoe-style parking brake ensures reliable static holding without altering the appearance of the rear axle. The kit also comes with mounting brackets, bearing retainers, and a rotor registration adapter for the best fitment. Hydraulic lines and parking brake cables are not included and must be purchased separately. This kit is engineered for balanced, consistent performance and retains a pedal feel close to factory, making it ideal for street, performance, or show applications.

INSTALLATION OVERVIEW

Installation of the kit should only be performed by experienced installers familiar with disc brake systems. The process begins with raising the rear wheels and removing the existing drum brakes to expose the axle assembly. The installer should verify kit contents against the included parts list and check for proper wheel clearance using the provided diagram. Next, the bracket assembly is mounted onto the axle housing flange, and the rotor registration adapter is aligned with the axle register. Calliper installation requires the careful use of shims and the correct torque on mounting bolts, with red Loctite® 271 applied to secure fasteners. After the assembly, it is crucial to perform proper brake bleeding and system testing to ensure a firm pedal and safe operation.

FITMENT AND COMPATIBILITY

This kit is designed specifically for use on the rear axle ends of 1958-1964 Olds and Pontiac vehicles. It is essential to verify that your vehicle’s axle housing flange, stud pattern, and wheel clearance match the kit’s specifications. Keep in mind that the kit does not include hydraulic lines or parking brake cables, and these items must be fitted separately. Additionally, while the kit is engineered for precision, any necessary adjustments or modifications to fitment should be done by someone experienced in brake system installations to maintain safety and performance.
