Alcon CRB343323232SLL B-Type Radial Mount Race Brake Caliper - 4-Piston

The Alcon CRB343323232SLL is a high-performance B-Type four-piston radial mount brake caliper engineered for motorsport applications. Part of Alcon's Advantage race caliper range, the CRB343 platform is a trusted choice in Rally, Group N+, Touring Car, and general circuit racing. This specific variant features 32/32/32mm stainless steel pistons (SLL suffix) and is designed for left-leading (LL) caliper positioning.

Key Features:

• 4-Piston B-Type architecture — two-piece construction with removable bridge for easy pad changes without removing the caliper from the vehicle
• Stainless steel pistons (32/32/32mm) — reduces heat transfer to brake fluid compared to standard aluminum piston variants
• Radial mount design — optimized for stiffness and precise brake force application
• Hard stainless steel wear plates — for long-term durability under high-heat race conditions
• Fixed pad retainer bars — increase caliper stiffness and simplify pad servicing
• Disc diameter range: ø280–343mm — versatile fitment across a wide range of rotor sizes
• Disc thickness range: 28–32mm
• Fluid inlet: 3/8-24 UNF (-3) female
• Dry weight: 2.40 kg (5.29 lbs) excluding pads — lightweight alloy construction
• Non-dust-sealed design — intended for track and competition use only, not street/road use

Compatible with Alcon B-Type brake pads (PNF4441 profile, also fits CRB332 calipers). The CRB343 caliper is widely used in GT racing, Touring Car, and rally disciplines, making it a proven solution for competitors demanding consistent, fade-resistant braking performance at the limit.
