Vanlison Rear Brake Master Cylinder Aluminum Alloy

Description

Product Overview

The Vanlison Rear Brake Master Cylinder is a precision‑engineered component designed to replace the OEM part #33D-2583V-00-00 on a wide range of Yamaha off‑road models. Crafted from a high‑grade aluminum alloy, the cylinder offers an optimal balance of strength and lightweight construction, reducing unsprung mass while maintaining structural integrity under repeated hydraulic pressure cycles. The unit measures 8 x 2.6 x 1 inches and weighs just 8.3 ounces, making it easy to handle during installation. Its painted exterior provides corrosion resistance and a clean appearance that matches factory aesthetics. The design incorporates a sealed piston and a stainless‑steel bore to ensure consistent fluid flow and minimal internal leakage, delivering reliable braking response even in demanding terrain.

Usage

This master cylinder is intended for Yamaha off‑road motorcycles such as the YZ125, YZ250, YZ450, WR250, and WR450 series produced between 2003 and 2022. It excels in environments where precise brake modulation is critical—whether navigating tight forest trails, tackling rugged desert dunes, or competing on motocross tracks. Riders who demand consistent rear brake feel will appreciate the cylinder’s smooth piston action, which reduces sponginess and provides a linear pressure curve. The plug‑and‑play design means the unit bolts directly into the existing mounting points, eliminating the need for custom brackets or extensive machining. Ideal for both seasoned mechanics and DIY enthusiasts, the cylinder can be installed in under an hour with basic hand tools.
