Alcon ALACIR5059D03HZRT-LL Cast Iron 4-Piston Rear Caliper Right Trailing

The Alcon ALACIR5059D03HZRT-LL is a cast iron, radial-mount, 4-piston rear brake caliper designed as a direct replacement for Alcon big brake kit applications. This is the right trailing caliper in the CIR5059 series, engineered to deliver consistent, high-performance braking in demanding on- and off-road conditions.

Key Features:

• Ductile iron caliper housing — provides maximum structural strength and stiffness with high resistance to impact and fatigue
• Epoxy acrylic paint over acid zinc finish — delivers proven corrosion protection for long-term durability in harsh environments
• High-temperature seal material — developed from motorsport applications to withstand extreme braking temperatures
• Wiper seal on every piston — prevents road grime, mud, and debris from entering the caliper bore
• Radial mount design — ensures precise caliper alignment and consistent pad-to-rotor contact
• Right trailing orientation — direct fitment replacement for applicable Alcon big brake kit configurations

Alcon is a globally recognized leader in the design and manufacture of high-performance braking systems for motorsport, OEM, and aftermarket applications. The CIR5059 caliper series is engineered to integrate seamlessly with compatible Alcon rotors and brake pads, maintaining OEM-level actuation compatibility.
