The Tektro HD-E740 Auriga Plus is a hydraulic disc brakeset designed specifically for e-bikes, offering a crucial motor cut-off feature for enhanced safety and control. Its key benefit is providing reliable stopping power coupled with the ability to automatically disengage the e-bike motor when the brake lever is pulled, a requirement for many e-bike systems. A caveat is that the electrical cut-off cable requires professional attachment to your e-bike's motor system, and the lever is not pre-attached, necessitating custom hose routing. This brakeset features an open system, 4-piston calipers, and Tektro's EZ Plug-in system for easier initial setup.

The EZ Plug-in system means the brake is pre-bled and pressure tested at the factory with a plugged hose and lever. This allows you to route and cut the hose to your desired length, then attach the lever without needing to bleed the brakes.
The brake itself is a hydraulic system, but the electrical cut-off function needs to be compatible with your specific e-bike's motor wiring. Professional installation is required to connect the cut-off cable to your motor system.
This brake is specifically designed for and compatible ONLY with 2.3mm thick rotors. Standard rotors may not be compatible.
No, the EZ Plug-in system is designed to be pre-bled. As long as the hose is cut cleanly and the barb/olive are installed correctly, no bleeding should be necessary.
The Tektro HD-E740 Auriga Plus uses Q13RS resin pads, which are standard and easy to find for replacement.
The lever is designed for a specific side (e.g., RH for right-hand side). Ensure you purchase the correct lever for your intended mounting position.
The approximate weight is 449g for the front and 469g for the rear, excluding rotor adapters and mounting bolts.
Although pre-bled, the connection at the lever might have introduced air. Ensure the barb and olive are correctly installed and the compression nut is tight. If issues persist, professional bleeding may be required.
This indicates an issue with the electrical connection of the cut-off cable to the e-bike's motor system. This requires professional diagnosis and repair by an e-bike mechanic or technician familiar with your specific motor.
Ensure the rotor is clean and compatible (2.3mm thickness). Check that the brake pads are properly seated and not contaminated. Bed in the pads and rotor if new. If noise persists, inspect pads for wear or damage.
Check for kinks or obstructions in the hydraulic hose. Ensure the lever is not binding on the handlebar or other components. Verify the two-piece clamp is not overtightened, causing the lever to stick.
