Frequently Asked Questions
Will Alcon ALABKF5459AX02 fit my vehicle?
This kit is listed for 2007-2018 Jeep Wrangler JK. Confirm the complete trim, factory brake package, hub and knuckle configuration, and every application note before ordering.
What is included with Alcon ALABKF5459AX02?

Which axle does this Alcon brake kit upgrade?
This configuration is for the axle position stated in the product title and specifications. 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.

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.
