4-Piston Bike Hydraulic Brake Kit with 2-Pin Waterproof Plug for MTB & eBikes
Elemex High-Performance Hydraulic Bike Brake Kit for MTB and eBikes

Product Overview
The Elemex 4-Piston Hydraulic Brake Kit is designed to provide powerful, stable, and reliable braking performance for eBikes and high-performance bicycles. Built with a 4-piston open hydraulic system, this brake kit delivers stronger clamping force, improved braking balance, and smoother control compared to conventional 2-piston brake systems.
Equipped with a hydraulic oil braking system and electric motor power-cut sensor, this kit is ideal for electric bikes where safety and immediate motor cut-off during braking are essential. The brake levers feature a 2-pin Male connector, making them compatible with many common eBike controllers. Forged aluminium components ensure durability, effective heat management, and consistent braking performance across a wide range of riding conditions.
