Wilwood 120-13863-N Powerlite 2R Radial Mount Brake Caliper 2-Piston Nickel Right

The Wilwood Powerlite PL2R Radial Mount Caliper (120-13863-N) is a high-strength, lightweight two-piston disc brake caliper engineered specifically for open wheel and formula car road racing competition. Designed for applications where maximum clamping efficiency must be achieved within a limited wheel envelope, this right-hand caliper delivers precise, consistent braking force alongside an optimized rotor diameter relationship.

Key Features:

• Machined billet aluminum body with offset 1.75" piston bores for superior strength-to-weight ratio
• Two-piston design with Thermlock pistons to minimize heat transfer from rotor to brake fluid
• Nickel-plated Quick-Silver body finish for corrosion resistance and clean appearance
• Top-loading quick-access 7912 pad type compatible with a wide variety of friction compounds
• Common radial stud spacing and mounting offsets for broad compatibility across open wheel and formula chassis
• High-temperature square section seals for reliable sealing under extreme racing conditions
• Internal damping springs and stainless steel bridge abutment plates to reduce pad rattle and brake squeal
• Internal fluid passages eliminate vulnerable external crossover tubes
• 2-piece bleed screws included for straightforward fluid bleeding and maintenance
• Right-hand (passenger side) mount — paired with MPN 120-13864-N for the left/driver side

The Powerlite PL2R series is purpose-built for competitive motorsport environments including formula road racing, sports car racing, rally, and similar disciplines where reduced unsprung weight and precise pedal feel are critical. The 7912 pad shape is available in multiple friction compounds to suit a wide range of track conditions and driving styles.
