Drag Specialties 1730‑0026 Rear Wheel Brake Cylinder Rebuild Kit for Harley FL & FLH (1963–1972)

OVERVIEW

A specialized rebuild kit designed to restore proper hydraulic sealing and drum engagement on vintage Harley-Davidson motorcycle rear brake cylinders. The kit contains precision-engineered brass and rubber components manufactured to replace worn factory internals. It provides a direct solution for maintaining stopping capability on classic FL and FLH touring chassis without requiring full cylinder replacement.

ENGINEERING & PERFORMANCE

Each component balances original equipment dimensions to ensure continuous piston travel and leak-free operation during heavy deceleration events. Heat-resistant materials and hardened steel hardware are selected to endure repeated thermal cycling and moisture exposure common in period-correct touring motorcycles. Factory-aligned tolerances eliminate internal fluid bypass and mechanical drag, delivering predictable braking response and reduced maintenance frequency.

WHY RIDERS CHOOSE THIS

Vintage Harley touring brakes demand exact bore tolerances to prevent fluid leakage and pedal fade under sustained loads. Riders prefer this kit because the included brass sleeves and precision seals replicate the original engineering needed for reliable deceleration on early Duo-Glide and Electra Glide frames. Assembled from trusted manufacturer specifications rather than generic imports, the components drop into existing casings to resolve spongy lever feel and deliver lasting safety across historical restoration projects.
