KustomTech Cable Brake Master Cylinder, 14mm Bore — Black Aluminum
Hey biker. This KustomTech master cylinder is designed for riders who want a clean cockpit: machined from a single block of aluminum with compact dimensions, it frees your handlebars from the bulky stock Harley master cylinder. The result: a clean line, a true custom signature.
Deep black anodized aluminum finish — the discreet version, perfect on a monochrome build.

For which project?
This part replaces a standard master cylinder on a custom motorcycle or chopper equipped with cable handlebar controls. If your handlebars still have stock Harley hydraulic controls, you'll need a pair of KustomTech cable controls to make the system work. Mounted under the seat or behind the tank, it's visually discreet and provides a clean, uncluttered look, free of black plastic.
Compatibility and assembly
The 14 mm (9/16″) piston bore covers most brake and clutch applications on custom Harley projects or similar. Before installation, always check the required oil volume for your caliper/slave cylinder and adjust the master cylinder size to the appropriate torque if necessary. If you have any doubts, the Holdfast team in Marseille can advise you via WhatsApp or in-store—we know the KustomTech line inside and out.

FAQ — Brake Master Cylinders
Hydraulic or cable-driven?
Hydraulic brakes offer modern, progressive braking with precise modulation. Cable (mechanical) brakes require more effort but give the pure vintage look of old-school choppers.
Approved for road use in France?
Yes. All KustomTech master cylinders are approved for European road use (ECE standard) and are compatible with motorcycle insurance. You can install them legally.
Does the system need to be bled?
Yes, absolutely after installation. Use DOT 4 or DOT 5.1 fluid depending on your motorcycle. Allow 30 minutes for a proper bleeding process.

Yanis –
Super clean pump, impeccable machining. Mounted under the seat of my Shovelhead, the handlebars are finally free. Thanks Holdfast for the advice on cable controls.
Thibaut –
Since I've been riding with this hidden master cylinder, I don't want to go back to the stock one. It completely frees up the handlebars visually.
Stephane_Deluxe –
Matches my Deluxe grips and levers perfectly. The set looks really cohesive now. Thanks for the advice.
Dave –
Great product. Only complaint is the instructions were in Italian but the web is full of install videos.
