Technical Specifications & Details
Component: Master Brake Cylinder / Lever Assembly (Set)
Compatibility: Jinling JLA-21B (250cc), Jinling JLA-931E (300cc), and similar Chinese quads (e.g., Haili SP-307-J)
Material: High-strength cast aluminum.
Features: Includes brake lever, brake light switch mount, and sight glass for level checking.
Benefit: OEM fit for straightforward installation and long-lasting performance.
Visual Compatibility: Before installation, perform a visual check. Compare the brake line connection (usually M10 banjo) and the handlebar mount diameter (22 mm standard) with your original part.
Cleanliness: Ensure no dirt enters the system during assembly. Always use new copper washers for the banjo bolt to prevent leaks.
System Bleeding: After replacing the cylinder, the entire braking system must be professionally bled. Any air trapped in the system will reduce braking efficiency and poses a serious safety risk.
Brake Fluid: Use only fresh brake fluid as specified by the manufacturer (usually DOT 4). Never mix different types of brake fluids.
