The Alcon BKF1559K18 front big brake kit upgrades supported 2016-2021 Toyota Tundra, Toyota Land Cruiser 200 Series, and Lexus LX570 applications with six-piston ductile-iron calipers and 355mm x 36mm internally vented rotors. Developed for heavy-duty, armored, towing, off-road, and performance use, this system is designed to reduce brake temperatures, lower pad work rate, and increase brake torque while retaining compatibility with the factory hydraulic system.
Key Features
- Six-piston ductile-iron front calipers with six 41.3mm pistons per caliper
- 355mm x 36mm internally vented front rotors
- 45 percent reduction in brake disc temperature rise compared with the factory system
- 42 percent reduction in pad work rate for longer pad and rotor service life
- 10 percent reduction in pedal effort and 10 percent increase in brake torque
- High-temperature seals and inboard bleed screws for demanding environments
- Designed for supported vehicles up to 9,900 pounds
- TUV-certified brake system

About Alcon
Alcon engineers braking systems for road, off-road, motorsport, defense, and specialized vehicle applications. Each kit is designed around a specific caliper, rotor, bracket, hydraulic, and wheel-clearance package, so the exact part number and application notes should be confirmed before purchase.

Frequently Asked Questions
Will this kit fit a 2022 or newer Toyota Tundra?
No. BKF1559K18 is for supported 2016-2021 XK50 Tundra applications. The redesigned 2022-and-newer Tundra uses a different brake-kit application.
Will my current wheels clear the Alcon calipers?
A 17-inch or larger wheel is required, but diameter alone does not guarantee clearance. Check barrel diameter, spoke profile, offset, and caliper envelope with Alcon's current BKF1559K18 wheel-clearance template before ordering.
Does the kit include brake pads and stainless brake lines?
Yes. The front kit includes the six-piston calipers, 355mm x 36mm rotors, AV1 pads, mounting brackets, hardware, and stainless steel brake lines.
Are vehicle modifications required?
The kit mounts to supported factory applications, but the dust shields may need to be trimmed or removed. It does not fit aftermarket spindles, and all application notes and wheel clearances must be verified before installation.
Does the system require bleeding and bedding?
Yes. Installation requires correct brake-line connection, a complete bleed and leak inspection, torque verification, and the Alcon pad-and-rotor bedding procedure before aggressive use.
Installation Instructions
- Confirm the exact vehicle application, factory spindle configuration, and wheel clearance before disassembly.
- Safely raise the vehicle, remove the front wheels, and remove the factory calipers and rotors.
- Trim or remove the dust shields only where required by Alcon's instructions.
- Install the supplied brackets, 355mm x 36mm rotors, and six-piston calipers using the specified hardware orientation.
- Install the supplied stainless steel brake lines without twists, interference, or tension through the full steering and suspension range.
- Bleed the hydraulic system, inspect for leaks, and torque all fasteners to the current Alcon and vehicle-manufacturer specifications.
- Reinstall the wheels, verify caliper clearance, and complete the prescribed pad-and-rotor bedding procedure.

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.
