Construction & Design

The master cylinder body is engineered for strength and reliability, featuring high-quality materials and precision machining. The remote flange mount design separates the master cylinder from the reservoir, allowing for flexible placement in confined spaces or custom brake setups. This design also helps reduce heat transfer from the engine bay to the brake fluid, improving system reliability.

The reservoir is crafted from billet aluminum and finished with a finned pattern that not only provides a distinctive look but also promotes passive cooling by increasing surface area. This helps maintain optimal brake fluid temperatures during demanding driving conditions, reducing the risk of brake fade. The compact size and lightweight construction make this master cylinder an excellent choice for performance vehicles where space and weight savings are critical.
