Will Alcon ALABKF1559BE74 fit my vehicle?
This kit is listed for 2021-2024 Ford F-150 Raptor, 2023-2024 Ford F-150 Raptor R. Confirm the complete trim, factory brake package, hub and knuckle configuration, and every application note before ordering.
What is included with Alcon ALABKF1559BE74?
The verified package includes Alcon 6-piston front caliper (pair); Vented slotted front rotors (pair); Alcon high-performance brake pads; Caliper mounting hardware and installation kit. Only components explicitly listed for this exact part number are included.
Which axle does this Alcon brake kit upgrade?
This configuration is for Front axle. Do not substitute a front, rear, or complete-vehicle kit with a similar rotor diameter.
Will my current wheels clear this Alcon brake kit?
Wheel diameter alone does not establish clearance. Verify spoke profile, barrel diameter, offset, caliper envelope, rotor size, and the current Alcon wheel-clearance template before ordering.
Does an Alcon big brake kit require bleeding and bedding?
Hydraulic brake work requires correct installation, bleeding, leak inspection, torque verification, and the pad and rotor bedding procedure supplied for the exact components. Professional installation is recommended when the installer is not qualified for brake-system service.
Installation Instructions
- Raise vehicle and remove front wheels using appropriate jack stands
- Remove factory brake calipers and disconnect brake lines carefully
- Remove factory rotors from hub assembly
- Mount Alcon rotors onto factory hubs per provided hardware
- Install Alcon 6-piston calipers using provided mounting hardware onto factory spindles
- Connect and bleed brake lines, purging all air from the system
- Reinstall wheels and torque lug nuts to factory specification
- Perform a gentle bedding procedure: 10 moderate stops from 40 mph to seat pads and rotors
Alcon
Shop Alcon big brake kits, calipers, rotors, replacement rings, brake pads, brackets, service hardware, and rotor temperature products by exact manufacturer part number. Match the complete vehicle, axle position, factory brake package, rotor dimensions, caliper family, wheel clearance, and included components before ordering. Alcon Big Brake Kits Alcon brake kits combine application-specific calipers, rotors, brackets, pads, lines, and installation hardware in front, rear, or complete-vehicle configurations. Piston count and rotor diameter do not establish fitment by themselves; the hub, knuckle, axle, factory brake package, wheel barrel, spoke profile, and kit part number must all match. Race, Street, Truck, and Off-Road Applications Select the brake system for the vehicle's actual use. Repeated track braking, towing, larger tires, added vehicle mass, and off-road driving can require different rotor capacity, pad compound, heat management, and service intervals.
