The system features 11-inch cast iron front brake rotors with a cross-drilled, slotted, and zinc-plated design to help reduce brake fade and improve braking efficiency. Cross-drilled and slotted rotors help evacuate gases, heat, and debris from the braking surface during aggressive braking, promoting better pad-to-rotor contact and more consistent stopping performance. The result is improved braking power and a performance-inspired appearance.

Matched single-piston cast iron calipers provide dependable clamping force and feature a natural finish for a clean, factory-style look. To complete the system, this kit includes new front spindles, a master cylinder, and a power brake booster, ensuring proper hydraulic pressure and power assist for disc brake operation. Brake lines are included, helping provide a more complete and streamlined installation.

Designed to work with a minimum recommended wheel size of 14x7, this LEED Brakes power front disc brake conversion kit is compatible with many factory and aftermarket wheel configurations, making it a versatile upgrade for GM AFX vehicles.
