Safety Through Full Braking Control! – Brake Lever Left with Master Cylinder

Complete Brake Assembly – Reliable power transmission for the rear brake

Optimize your scooter's braking performance! This left-hand brake assembly is a complete unit specifically designed for scooters with hydraulic rear brakes (or combined braking systems). It includes the master cylinder, the integrated reservoir, and the ergonomic brake lever. With the integrated 10mm mirror thread, your rearview mirror can be mounted directly without additional adapters. Made of robust die-cast aluminum, this assembly ensures a constant pressure point and maximum safety on the road.

Installation & Maintenance Instructions: (For guidance purposes only)

• Visual Compatibility: Before installation, perform a visual check. Compare the lever shape, the brake line connection (banjo bolt), and the brake light switch connector with your old part.

• Preventing Leaks: Always use new copper sealing washers when connecting the brake line to ensure a long-lasting, tight seal.

• Brake Fluid: Fill the system only with the specified fluid (usually DOT 4). Be careful not to spill brake fluid on painted surfaces, as it is highly corrosive.

• System Bleeding: After installation, a complete bleeding of the brake system is vital for safety. Check the pressure point several times while stationary before operating the vehicle.

• Lubrication: A small drop of grease on the lever's pivot bolt maintains smooth operation and prevents premature wear of the mechanics.
