Tektro HD-E3940 e-Bike Hydraulic Front Brake | 4-Piston Power & Integrated Cut-Off
Stop on a dime, every time. Upgrade your e-bike’s stopping power with the Tektro HD-E3940, a heavy-duty hydraulic braking system engineered specifically for high-speed electric bikes like the Vamoose Toro and Matador.
Combining massive quad-piston clamping force with an integrated electronic safety switch, this front brake kit offers the ultimate blend of performance and security.
Key Features:
- Superior Quad-Piston Caliper: Features a new 4-piston design that provides significantly more surface area and clamping force than standard 2-piston brakes—essential for heavy e-bikes and steep descents.
- Integrated Power Cut-Off: Built-in reed switch sensor instantly cuts motor power the moment you engage the lever, ensuring shorter stopping distances and preventing motor "push."
- E-Bike Optimized Lever: Ergonomic 3-finger aluminum lever with reach adjustment, designed for comfortable, high-leverage braking even with gloves on.
- Maximum Heat Dissipation: Designed to pair perfectly with oversized 203mm rotors (2.3mm thickness) to eliminate brake fade during prolonged use.
- Easy Maintenance: Uses non-corrosive mineral oil and features a simplified bleeding design for long-term reliability.
