Yamaha Motor Co., Ltd. 3Y6-25151-00-00 Brake Camshaft

The Yamaha 3Y6-25151-00-00 Brake Camshaft converts lever movement into cam-driven expansion to actuate the brake shoes in motorcycle drum brake systems, delivering precise shoe engagement within Yamaha motorcycles where reliable actuation is required. Manufactured from hardened steel (OEM grade) and heat-treated for wear resistance, this cam-profile shaft is designed for controlled expansion and integrates within the brake hub assembly to drive the internal cam mechanism. It operates in a mechanical linkage-driven drum brake system to produce consistent braking performance and maintain proper shoe contact with the drum, contributing to safe operation. This part is commonly used in maintenance, repair, and overhaul tasks that require OEM-compatible actuation components and model-specific fitment for Yamaha motorcycles. Related replacements include Yamaha 2A6-25151-00-00 Brake Camshaft, Yamaha 3J8-25151-00-00 Brake Camshaft, and Yamaha 1T3-25151-00-00 Brake Camshaft.
