When replacing the rear caliper with a GALE SPEED or Brembo opposed 2-piston caliper (φ32, φ34), the stroke of the brake pedal may be reduced depending on the ratio, making it difficult to control. The GALE SPEED rear master cylinder has a piston diameter of φ12 and is designed to match the leverage ratio of general racing steps. This realizes a delicate and controllable rear brake system. ■Specifications Type: Mounting pitch 45mm\/Rod end M8 Color: Black Piston size: φ12 Compatible caliper: Piston diameter φ32\/φ34 opposed 2-piston Bolt pitch: P1.00 Fluid tank: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■Notes *The image is for illustrative purposes only.
