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 not included, allowing flexibility for custom routing or replacement based on your vehicle's setup.

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.
