In the case of a stock rear master cylinder, when changing the rear caliper to an opposed 2-piston caliper (φ32, φ34) made by GALE SPEED, Brembo, etc., the stroke width of the brake pedal may become smaller depending on the ratio, making it difficult to control. there is.
On the other hand, the Gale Speed rear master cylinder has a piston diameter of φ12 and was designed to match the lever ratio of a general racing step. This creates a delicate and controllable rear brake system.
