Upgrade rear braking performance with the Brembo GP2 SS Rear Upgrade Brake Caliper, part number 120A44110. Designed for riders seeking improved control and consistent braking feel, this high-performance caliper combines Brembo engineering with a durable construction suited to demanding street, track, and performance applications. Its two-piece design supports precise operation while providing a strong, dependable foundation for rear brake performance.
The caliper uses dual 34mm pistons to deliver balanced hydraulic force and predictable engagement. This piston configuration helps provide accurate braking control, allowing riders to manage rear brake input with greater confidence during corner entry, corner correction, and controlled deceleration. Optimized modulation and pedal feel make the GP2 SS a practical upgrade for applications where the original rear brake system does not provide the desired response or consistency.
A durable anodized black finish provides a clean, performance-focused appearance while helping protect the caliper against normal environmental exposure. High-performance sintered brake pads are included, offering a convenient installation solution and dependable friction characteristics when paired with a properly matched braking system. Each caliper also carries individual production batch identification to support manufacturing traceability. Verify mounting configuration, brake system compatibility, and required hardware before installation. Professional installation and proper brake-system bedding are recommended for safe, reliable operation.
