KustomTech Deluxe brake master cylinder with polished aluminum and brass cable
This is the part that will revolutionize the braking system of your custom motorcycle. The KustomTech Deluxe cable-operated master cylinder is a small marvel of Italian engineering, machined from a block of billet aluminum and adorned with polished brass for that vintage style that all riders love.
Compact and versatile
What makes this master cylinder unique is its ultra-compact size. Its small external dimensions allow it to be mounted virtually anywhere on your motorcycle: under the frame, behind the gearbox, or even in plain sight if you want to showcase the quality of your parts. The two mounting holes accept a center-to-center distance of 33 to 38 mm, offering great mounting flexibility.
14mm piston for precise braking
Equipped with a 14 mm (9/16″) piston, this master cylinder is suitable for both brake and hydraulic clutch systems. The cable actuation eliminates the limitations of traditional handlebar-mounted master cylinders, making it ideal for builds with KustomTech cable-operated handlebar controls.
High-end Italian manufacturing
Each master cylinder is CNC machined in KustomTech's workshops in Italy. Billet aluminum ensures optimal strength and precision, while polished brass inserts add that touch of vintage elegance that characterizes the brand. The finish is impeccable: smooth surfaces, sharp edges, and a mirror polish.

Maintenance frequency?
Recommended every 2-3 years depending on mileage. If brake pressure drops or if there is brownish fluid in the reservoir, that's a sign.

Yes, this kit works on both KustomTech ranges. Just check the bore (12 or 14 mm).
Do I need a specialist mechanic?
No, but good cleanliness and patience are key. Hydraulic parts = no dust, no mineral oil. Use clean DOT4 fluid.

The braking is progressive and powerful. Much better than the makeshift setup I had before. KustomTech is on another level.

Impeccable machining, as always with KustomTech. The polished brass on the aluminum is magnificent. Installation with the Deluxe controls is a breeze.
