40-083 K-Tech, Custom rear master cylinder hydraulic. Polished

When space is at an absolute premium, this Kustom Tech custom rear master cylinder is the answer. Billed as the smallest of the small, this miniature master cylinder is machined from billet aluminum and finished in a high-quality polish. It features a 14mm, or 9/16-inch, piston diameter, making it capable of operating most rear brake calipers effectively despite its tiny footprint. This universal component is perfect for custom frames or builds where you want to hide the rear braking components as much as possible. It is a testament to Kustom Tech's ability to blend extreme minimalism with functional engineering.
