MINI AND MOKE DUAL CIRCUIT BRAKE MASTER CYLINDER [GMC227CL]
PRODUCT OVERVIEW
Dual circuit tandem brake master cylinder to suit Mini and Moke applications using a dual circuit braking system.
This master cylinder is an important safety-critical component in the hydraulic brake system. The tandem design separates the brake circuits, helping provide a safer and more modern brake system layout compared with single circuit systems.
A worn or leaking brake master cylinder can cause a soft pedal, poor braking performance, internal bypassing, or brake fluid leakage around the pedal area. If your braking system is being rebuilt or upgraded, fitting the correct master cylinder is essential.

When using this master cylinder, you must reverse your brake lines due to the design of the new tandem master cylinder.

BRAKE FLUID WARNING
Use only the correct DOT4 or DOT5 brake fluid.
These cylinders are not designed to use other fluids such as Castrol SRF racing fluid or any mineral-based fluid. Using the wrong fluid can damage the internal seals and may cause brake failure.
