Clutch Masters Clutch Master Cylinders Hydraulics 13-25 BRZ / FRS / 86 | Adjustable Throw | Hydraulic Clutch Upgrade
Overview
The Clutch Masters Clutch Master Cylinder kit is a precision-engineered hydraulic upgrade designed specifically for the 2013-2025 Subaru BRZ, Scion FRS, and Toyota 86 platforms. This billet aluminum master cylinder replaces the factory unit to provide a crisper, more responsive clutch pedal feel and eliminates the factory clutch delay valve for immediate clutch engagement. Ideal for enthusiasts upgrading their clutch system or those experiencing wear and leaks in the OEM master cylinder, this kit ensures your hydraulic system matches the demands of aggressive driving and spirited shifting.
Crafted from 6061 billet aluminum, this master cylinder is built with adjustability and durability in mind. The design allows fine-tuning of the master cylinder’s position relative to the firewall and pedal, as well as adjustable push rod length and clevis positioning. This flexibility lets drivers dial in clutch engagement and disengagement points to suit their driving style and clutch setup. The kit also includes a remote reservoir and all necessary fittings for a complete, plug-and-play installation that works seamlessly with the OEM slave cylinder.
Removing the clutch delay valve is a key benefit for quick-shifting drivers, especially during rapid 1-2 gear changes where throttle application occurs before full clutch engagement. By eliminating this delay, the clutch engages immediately, improving shift response and drivability. This upgrade is particularly valuable for track enthusiasts and performance drivers who demand precise clutch control without sacrificing reliability. For those needing some clutch slip to protect drivetrain components, Clutch Masters offers a tunable Flow Control Valve as an optional complement.

Installation & Compatibility
Installation of the Clutch Masters master cylinder kit is moderately complex and may require some mechanical experience. The kit is designed as a direct replacement for the factory master cylinder and works with OEM slave cylinders, making it largely bolt-on. However, due to the extensive adjustability of the master cylinder position and push rod length, it is critical to properly set the clutch pedal throw to avoid overthrowing the clutch diaphragm. Adjustments to the pedal stop or master cylinder mounting location may be necessary. No special tools beyond standard hand tools and the included jam nut tool are required.
