Zoom HB-876E Electric bike hydraulic brake set adopts a left front and right rear braking method, which fits the habit of most American people.

The 4-piston hydraulic brake caliper has 20% higher braking force and 150% higher wear resistance than the same level of dual-piston brakes.

Just a simple installation makes for the safest and most reliable braking!

Note: Do not remove the "Red piston block" when installation, otherwise it will cause oil leakage or scrap the oil hydraulic disc.

High-quality material: CNC aluminum alloy body, three-finger brake lever, integrated oil cylinder system. The handlebar diameter is 22 mm / 0.87 in. The rear caliper hose and control lever are separated for easy internal routing.

This brake system comes with a brake automatic power-off sensor and is compatible with 2-pin connectors. When you brake, the power output is automatically cut off, ensuring quick and efficient braking.

Compatible with 160/180mm rotors, IS/PM universal mount adapter (only for e-bike models with calipers mounted on the left side)

When purchasing, please pay attention to whether the length of the hose matches your electric bicycle. The hose has been pre-coated with mineral oil and can be used directly without oiling.
