When replacing the rear caliper with a GALE SPEED or Brembo opposed 2-piston caliper (φ32, φ34), the brake pedal's stroke may become shorter 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 lever ratio of general racing steps. This achieves a delicate and controllable rear brake system. ■Specifications Type: Mounting pitch 40mm\/49mm\/rod end M8 Color: Black Piston size: φ12 Compatible calipers: Piston diameter φ32\/φ34 opposed 2-piston Bolt pitch: P1.00 Fluid reservoir: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■Notes *The image is for illustration purposes only.
