Alcon CRR280/25-35RT 2-Piston Radial Mount Racing Brake Caliper Right Hand Trailing

The Alcon CRR280/25-35RT is a high-performance 2-piston radial mount racing brake caliper designed for motorsport applications including rally, hillclimb, single seater, and saloon car racing. This right-hand trailing configuration caliper is part of Alcon's acclaimed CRR280 Advantage Range, engineered to deliver exceptional braking performance under extreme track conditions.

Key Features:

• Radial mounting design for maximum rigidity and consistent, firm pedal feel
• Ø34.9mm aluminum pistons as standard for optimal heat dissipation
• 2kg anti-knock back springs to maintain consistent pad-to-rotor contact
• Pad retaining wire system for quick and easy pad changes during pit stops
• Stainless steel fluid transfer bridge pipe for durability
• Compatible with disc diameters ranging from Ø250mm to Ø280mm
• Accepts disc thickness range of 22.9mm to 25.4mm (ventilated rotors)
• 3/8-24 UNF (-3) female fluid inlet for standard brake line connections
• Lightweight construction at approximately 1.30kg dry weight (excluding brake pads)

Technical Specifications:

• Piston Configuration: 2-piston radial mount
• Piston Diameter: Ø34.9mm aluminum (stainless steel pistons available as upgrade)
• Mounting Position: Right-hand trailing (RT)
• Compatible Pad Reference: Alcon 3451/42 or 3451/47 pad shapes
• Brake Fluid Fitting: 3/8-24 UNF (-3) female thread

This caliper is ideal for rear brake applications in competitive motorsport where reliability, consistent performance, and serviceability are critical. The radial mounting design ensures the caliper remains securely positioned under heavy braking loads, while the anti-knock back springs prevent piston retraction that can occur with wheel bearing deflection or rotor runout.
