DRAG SPECIALTIES Repair Kit (Ref. 20171) — a reconditioning kit for the rear brake master cylinder, designed to restore the functionality of the braking system on many Harley-Davidson models. This part is intended for riders seeking a durable maintenance solution for their Dyna, Roadster, or vintage/classic touring machine.
This kit allows for the reconditioning of the rear master cylinder without replacing the entire unit: ideal for periodic maintenance or refurbishment after wear. The supplied components are suitable for the specified bore diameter and fit into standard configurations of rear master cylinders. Easy to install for an informed amateur mechanic or workshop, it enables a clear lever travel and precise control of the rear brake.
Compatibility: designed to be compatible with a wide range of listed Harley-Davidson models — including FXDLS 1800 ABS Low Rider S (2017), FXDWG 1690 ABS Wide Glide (2017), and FXDL 1690 ABS Low Rider (2017). Check the reference and bore diameter before installation.
