Tektro HD-E3940 Dorado Quad-Piston Hydraulic Rear Brake
Take control of your stopping power with the Tektro HD-E3940, a premium 4-piston hydraulic brake system engineered specifically for the high-speed and high-torque demands of modern electric bikes.
While standard 2-piston brakes can struggle with the weight of an e-bike, the Dorado’s quad-piston caliper provides massive surface area for consistent, fade-free braking on long descents. This rear-specific assembly comes pre-bled and includes an integrated motor cut-off sensor for a true "plug-and-play" safety upgrade.
Key Features
- Quad-Piston Dominance: Features a forged aluminum 4-piston caliper that delivers explosive stopping power and superior heat dissipation compared to standard systems.
- Integrated Safety Sensor: Equipped with a quick-connect power cut-off sensor (EJ1 cable) that immediately disengages the e-bike motor when you pull the lever.
- Ergonomic 3-Finger Lever: The cast aluminum lever features a comfortable 3-finger blade with an adjustable reach (83–88mm) to fit any hand size.
- Heavy-Duty Construction: Designed to work perfectly with 2.3mm thick rotors, providing a stiffer, more reliable braking feel under heavy loads.
- Easy Maintenance: Uses a universal oil route and non-corrosive mineral oil, making seasonal bleeds and maintenance straightforward.
