Power Front Disc Brake Conversion Kit Cross Drilled and Slotted Rotors with 9" Chrome Booster Cast Iron Chrome Top M/C Adjustable Proportioning Valve

Upgrade your braking system with this LEED Brakes' GM AFX Power Front Disc Brake Conversion Kit with Cross-Drilled & Slotted Rotors and 9″ Chrome Booster, engineered to deliver improved safety, reliability, and consistent stopping performance. Designed as a complete front disc brake upgrade, this kit replaces factory drum brakes with modern single-piston front disc brakes for enhanced braking confidence and control.

This GM AFX front disc brake complete kit includes everything required to mount single-piston disc brake calipers directly to the control arms of your vehicle. All components included are brand-new, high-quality, precision-machined parts built to ensure proper fitment, durability, and long-term performance.

The system features 11-inch cast-iron front brake rotors with a cross-drilled and slotted design and zinc plating to help reduce brake fade and improve braking efficiency. Cross-drilled and slotted rotors allow gases that build up between the brake pad and rotor during heavy braking to escape more effectively. This improves pad-to-rotor contact, resulting in increased braking power and more consistent stopping performance—while also delivering an aggressive, performance-focused 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.

This LEED Brakes power front disc brake conversion kit is designed to work with a minimum recommended wheel size of 14x7, making it compatible with many factory and aftermarket wheel configurations.
