Included in the kit are standard rotors, single-piston calipers with integrated parking brake functionality, caliper brackets, rear parking brake cables, rear axle lines, rubber brake hoses, and a comprehensive hardware kit with installation instructions. This ensures you have everything needed for the conversion. Compatibility requires 15-inch or larger wheels and a 7.5-inch rear axle.
