Power Front Disc Brake Conversion Kit Cross Drilled and Slotted Rotors with 9" Chrome Booster Cast Iron Chrome Top M/C Disc/Disc Side Mount for GM AFX

Upgrade your braking system with this LEED Brakes GM AFX power front drum-to-disc brake conversion kit, engineered to deliver improved safety, reliability, and consistent stopping performance. Designed as a complete front disc brake upgrade, this kit replaces outdated factory drum brakes with modern single-piston disc brakes for stronger braking response, improved pedal feel, and greater confidence behind the wheel.

This GM AFX front disc brake 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 adding 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 included, allowing for 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.
