Return PolicyThe Wilwood 140-16907 DynaPro Radial Big Brake Front Kit is a high-performance front disc brake upgrade engineered specifically for use with Wilwood Tri-Five Pro Spindles on 1955-1957 Chevrolet full-size models, including Bel Air, Nomad, One-Fifty, Two-Ten, Sedan Delivery, and Del Ray applications. Designed for street performance, pro-touring, and track-oriented builds, this kit combines lightweight components with advanced braking technology to deliver significantly improved stopping power, heat management, and pedal feel.
The kit features forged billet Narrow DynaPro 4-piston radial-mount calipers finished in red or black, paired with 12.19-inch Plain Face or Drilled & Slotted rotors and lightweight aluminum hub assemblies. Wilwood's radial-mount caliper design provides enhanced rigidity and even pad loading, while the large-diameter rotors improve heat dissipation during aggressive driving. Complete with BP-10 performance brake pads, bearings, seals, and installation hardware, the system is designed to complement upgraded wheels, tires, and suspension systems while maintaining consistent braking performance.
