Alcon CRB343323232SRL B-Type Radial Mount Race Brake Caliper - 4-Piston

The Alcon CRB343323232SRL is a motorsport-grade, 4-piston radial mount B-Type brake caliper from Alcon's Advantage Range, engineered for demanding race and rally applications. This two-piece caliper features a removable bridge design and is built for sustained high-performance braking in the most punishing conditions on track or stage.

Key Features:

• 4-Piston Radial Mount: Radial mounting design delivers maximum rigidity and a firm, consistent brake pedal feel under hard braking
• Differential Piston Diameters: Unequal piston sizing minimizes pad taper wear, extending pad life and maintaining even contact across the friction surface
• Stainless Steel Pistons: Stainless steel pistons reduce heat transfer to brake fluid, helping protect against brake fluid boil and vapor lock under extreme thermal load
• 2 kg Anti-Knock Back Springs: Prevents piston knock-back under high suspension or steering inputs, maintaining consistent pedal travel
• Hard Stainless Steel Wear Plates: Protects the caliper body from abrasive pad wear, extending caliper service life
• Fixed Pad Retainer Bars: Increases overall caliper stiffness; caliper must be removed from vehicle to change brake pads
• Two-Piece Construction with Removable Bridge: Classic B-Type architecture for serviceability and structural strength
