DELUXE LINE BRAKE MASTER CYLINDER 12mm (15/32”) ALUMINUM & BRASS (polish)

Deluxe master cylinder in polished aluminum and brass — the part that makes all the difference

On a custom motorcycle, every detail counts. This Deluxe Line brake master cylinder, crafted from machined aluminum and polished brass, replaces the original part with a work of mechanical art. Made with watchmaker-like precision, it transforms your motorcycle's handlebars into a museum piece—without sacrificing braking performance.

Machined aluminum + polished brass

The body is machined from a solid block of aluminum , making it lightweight and corrosion-resistant. Hand-polished solid brass accents provide that high-end vintage touch that distinguishes a true custom build from a mere accessory. The brass will develop a natural patina over time for an even more authentic look.

Braking performance preserved

12mm (15/32″) piston diameter , compatible with most disc brake systems. OEM-quality seals ensure a perfect seal and precise lever feel. This isn't just a decorative part—it's a truly functional and reliable braking component.

1-inch handlebar mount

Designed for 1-inch (25.4 mm) handlebars , standard on most Harley-Davidson and custom motorcycles. Right-side mounting. Hydraulic connections are standard to fit existing brake lines.
