Alcon ALACIR5459L07HZLT Cast Iron 4-Piston Brake Caliper Left Hand

The Alcon ALACIR5459L07HZLT is a high-performance cast iron 4-piston brake caliper engineered for demanding motorsport and heavy-duty off-road applications. Built to Alcon's exacting racing standards, this left-hand caliper delivers exceptional thermal capacity and consistent braking force under extreme conditions.

Key Features:

• Cast iron construction for superior heat absorption and thermal stability compared to aluminum alternatives
• 4-piston monoblock design with staggered 54mm/59mm bore sizing for optimized pad contact and even wear
• Left-hand (driver-side) caliper — confirm fitment with right-hand counterpart for axle pairing
• HZ-series hydraulic specification for direct hydraulic actuation
• Radial mount interface for rigid, deflection-free installation
• Compatible with Alcon big brake kit rotor packages in the CIR5459 family
• Designed and manufactured by Alcon Brakes, a UK-based motorsport braking specialist with decades of racing pedigree

Alcon cast iron calipers are a preferred choice in off-road racing, rally, and 4x4 competition builds where rotor size and sustained braking performance are critical. The iron body provides a natural advantage in high-heat, high-load scenarios where aluminum calipers can experience fade or distortion. This caliper is a direct replacement or upgrade component within compatible Alcon brake system kits.
