4-Piston Hydraulic E-Bike Disc Brake Set with 3-Pin Motor Cutoff Connectors
4-Piston Hydraulic E-Bike Disc Brake Set with 3-Pin Motor Cutoff Connectors
Powerful stopping performance designed specifically for electric bicycles.
This 4-Piston Hydraulic E-Bike Brake Set delivers the increased braking power required for today's high-performance electric bicycles. Built with forged aluminum calipers and hydraulic mineral oil operation, these brakes provide exceptional stopping force, improved heat management, and consistent braking performance under heavy loads.
Unlike standard bicycle hydraulic brakes, this system includes integrated yellow 3-pin motor cutoff connectors that communicate directly with compatible e-bike controllers. When the brake lever is activated, power to the motor is immediately interrupted, improving rider safety and reducing stopping distance.
The four-piston caliper design creates greater pad contact and more braking force than traditional two-piston systems, making these brakes an excellent upgrade for powerful hub motor and mid-drive electric bikes.
Designed for compatibility with many Bafang-powered e-bikes, conversion kits, and electric bicycle systems utilizing yellow 3-pin brake cutoff connections.
