Alcon ALACIL1559BE38HZLT-RL021A01 6-Piston Iron Brake Caliper Front Left

The Alcon ALACIL1559BE38HZLT-RL021A01 is a heavy-duty 6-piston ductile iron brake caliper designed for high-performance truck and off-road applications. This is the front left (driver side) unit, built on Alcon's proven 1559-series lug-mount platform and engineered to deliver motorsport-grade braking performance in demanding real-world conditions.

Decoded from Alcon's part number nomenclature, this caliper features an iron (I) housing with a lug-mount (L) configuration, staggered piston bores of 44.5 / 41.3 / 44.5 mm, and low-friction coated (HZ) pistons — delivering exceptional clamping force, consistent pedal feel, and reduced pad taper wear.

Key Features:

• Ductile iron caliper housing — provides maximum strength and stiffness with high resistance to fatigue and impact
• 6-piston design with staggered bore sizes (44.5 / 41.3 / 44.5 mm) for superior brake pressure and even pad wear
• Low-friction coated pistons for reduced operating temperatures and extended seal life
• Epoxy acrylic paint over acid zinc finish for maximum corrosion protection
• Advanced wiper seals around each piston — heat resistant and designed to exclude road grime and contaminants
• Lug-mount (radial-compatible) design for rigid, deflection-free caliper mounting
• Front Left (driver side) orientation
• Compatible with Alcon's factory ABS-balanced brake system — no warning lights or sensor issues

This caliper is sourced from Alcon's armored and military vehicle program, representing the same hardware trusted in some of the world's most extreme braking environments. It is the direct replacement or upgrade caliper for Alcon's 1559-series big brake kit applications.
