When upgrading the braking system, the brake master cylinder needs to be appropriately matched to the increased capacity and requirements of the brake system. Our R35 GT-R Brake Master Cylinder Conversion Kit provides a larger-volume master cylinder solution designed to complement high-performance brake conversions.

Developed specifically for R32, R33 and R34 GT-R applications, our conversion is the first of its kind to utilise the factory R32–R34 brake booster while integrating a genuine R35 GT-R brake master cylinder.

The system combines a genuine R35 GT-R master cylinder with a precision-engineered billet aluminium conversion adapter, allowing the larger master cylinder to integrate with the vehicle's existing factory brake-booster and brake-line configuration.

Engineered for Motorsport-Level Demands

The conversion adapter is manufactured from billet aluminium and has been engineered specifically for the demands of high-performance braking applications.

The adapter has undergone Finite Element Analysis (FEA) to evaluate structural rigidity and ensure the design is capable of withstanding the loads generated during demanding braking conditions.

For additional durability and long-term reliability, the conversion utilises stainless-steel fittings in critical connection points.

Every aspect of the conversion has been developed with the goal of maintaining a rigid, secure and reliable connection between the factory brake booster and the larger R35 GT-R master cylinder.

Genuine R35 GT-R Master Cylinder

The kit uses a brand-new genuine R35 GT-R brake master cylinder, rather than relying on an existing or potentially aged master cylinder.

The larger master cylinder provides increased fluid capacity and is designed to deliver an appropriate hydraulic response for upgraded brake systems, helping achieve improved and more consistent brake pedal characteristics.

The conversion is designed around the vehicle's factory brake system, with the required billet conversion adapter, stainless fittings, reducer and spacers supplied to complete the installation.

Why Upgrade the Master Cylinder?

When increasing the size and performance of a braking system, the master cylinder is an important part of the overall hydraulic system.

Upgrading the calipers and rotors can increase the system's fluid requirements. The R35 GT-R master cylinder provides greater fluid capacity, helping deliver an appropriate hydraulic response when paired with a suitably configured high-performance brake system.

Rather than upgrading the calipers and rotors in isolation, this conversion considers the braking system as a complete package—including hydraulic capacity, brake-booster compatibility, pedal response and structural integrity.

The result is a purpose-designed solution that combines a genuine R35 GT-R master cylinder, the factory R32–R34 brake booster and a FEA-validated billet aluminium adapter, creating a robust foundation for high-performance braking applications.
