TEKTRO HD-E3940 E-BIKE 4-PISTON HYDRAULIC BRAKE SET
POWERFUL STOPPING CONTROL WITH INTEGRATED MOTOR CUT-OFF
Conquer steep descents and heavy loads with the Tektro HD-E3940 4-Piston Hydraulic Disc Brake Set. Specifically engineered for the high-torque demands of electric bikes and cargo bikes, this system features a robust 4-piston forged caliper for superior clamping force and heat management. Crucially, the levers come equipped with integrated motor cut-off sensors, ensuring your motor assistance stops immediately when you brake for a safer ride.
KEY FEATURES
- 4-Piston Stopping Power: The forged aluminum caliper houses four pistons (2 opposing pairs), providing significantly more braking torque and modulation than standard 2-piston brakes, essential for controlling heavy e-bikes.
- Integrated Motor Cut-Off Sensors: Both brake levers feature built-in electronic sensor switches with cables. When the lever is pulled, the signal cuts power to the e-bike motor instantly, enhancing safety and preventing brake drag.
- High-Performance Mineral Oil: Utilizes a closed hydraulic system filled with non-corrosive mineral oil, offering consistent lever feel and requiring less frequent maintenance compared to DOT fluid systems.
- Thick Brake Pads: Compatible with Tektro Q13RS metal ceramic or resin pads (5mm thickness), offering excellent durability and bite for all-weather riding conditions.
- Post Mount Standard: Designed for standard 74mm Post Mount frames/forks. Compatible with 160mm, 180mm, and 203mm rotors (adapters and rotors sold separately).
