4-Piston Hydraulic Disc Brake Kit for E-Bike & Scooter | 160mm Rotors

This Buachois hydraulic disc brake kit is designed for riders who want stronger braking performance and better control for electric bikes and scooters. The set uses 4-piston calipers, helping deliver more stable and powerful braking force during daily riding and higher-load use.

It comes with 160mm rotors and is pre-loaded with mineral oil, making installation more convenient. The brake system also supports automatic power-off braking, and the product listing states compatibility with 2-pin and 3-pin connectors, making it suitable for many electric bike and scooter applications.

The kit includes an 890mm front hose and a 1740mm rear hose, which can fit a wide range of common e-bike and scooter setups. It also uses semi-metal brake pads and ergonomic three-finger brake levers, helping balance braking feel, control, and durability. The levers are designed for 22.2mm handlebars.

This is a practical brake upgrade choice for riders looking for improved stopping power, electric cut-off protection, and a complete hydraulic brake solution.

Please confirm your handlebar diameter is 22.2mm and check whether your current electric brake connector matches the 2-pin or 3-pin power-off interface before purchase.
