Product Information

Full details

The Tektro HD-E740 Auriga Plus brake is a hydraulic disc brakeset designed for ebikes requiring a motor cut-off when the brake lever is engaged. Its primary benefit is enhanced safety through automatic motor interruption, crucial for ebike performance and rider control. A caveat is that the motor cut-off cable requires professional installation. This pre-bled, open-system brake features 4-piston calipers, EZ Plug-in system for easy hose management, and is compatible with 2.3mm rotors.

FAQs

Do I need to bleed the brakes after connecting the hose?

No, the Tektro HD-E740 Auriga Plus comes pre-bled. You only need to bleed it if you disconnect the hose from the lever or caliper after the initial setup, or if air enters the system.

Can I use rotors other than 2.3mm thickness?

No, these brakes are specifically designed and tested for compatibility with 2.3mm thick rotors only. Using different thicknesses may compromise performance and safety.

What type of brake fluid does this system use?

This hydraulic brake system uses mineral oil. Do not use DOT fluid, as it can damage the seals.

How do I connect the motor cut-off cable?

The motor cut-off cable requires connection to your specific ebike's motor controller. This is a complex wiring task and must be performed by a professional ebike mechanic to ensure correct functionality and avoid damage to the electrical system.

What is the difference between this and a standard Tektro brake?

The key difference is the integrated motor cut-off sensor, designed specifically for ebikes to enhance safety by disengaging the motor when braking.

How often should I replace the brake pads?

Brake pad life depends on riding conditions, frequency, and braking habits. Inspect the Q13RS resin pads regularly. Replace them when the pad material wears down to approximately 1mm thickness.

Troubleshooting

Brake lever feels spongy or weak

The system may contain air. Bleeding the brakes is required. Consult the Tektro service manual or a professional mechanic, especially if unsure about the motor cut-off wiring.

Motor does not cut off when brake lever is pulled

The motor cut-off wire is likely not connected correctly or is faulty. This requires inspection and proper connection by a qualified ebike technician.

Brake noise (squealing or grinding)

Ensure rotors are clean and free of contamination. Check pad alignment and ensure they are not worn out. Bed in new pads and rotors properly.

Brake lever is loose or wobbly

Tighten the two-piece clamp bolts securing the lever to the handlebar. Ensure the handlebar is clean and dry where the clamp attaches.

Pros and Cons

Pros

  • Enhances ebike safety with automatic motor power cut-off.
  • Pre-bled system with EZ Plug-in simplifies initial setup.
  • Powerful 4-piston caliper design for strong, controlled braking.
  • Durable forged aluminum construction.
  • Designed for straightforward maintenance and pad replacement.

Cons

  • Motor cut-off requires professional wiring to the ebike's motor system.
  • Compatibility limited to 2.3mm thick rotors only.
  • Lever is not attached to the hose out of the box, requiring connection.
  • Brake hose length may need to be customized (cut and re-attached).

Setup, Compatibility & Care

Setup:

  1. Hose Management: Route the brake hose through your ebike frame. If necessary, cut the hose to the desired length using a sharp, dedicated hose cutter. Ensure the cut is clean and perpendicular.
  2. Hose Connection: Insert a barb into the cut end of the hose. Attach an olive to the hose, then insert the hose assembly into the brake lever, ensuring the olive is seated against the lever body. Secure the compression nut.
  3. Motor Cut-Off: Connect the cut-off cable to your ebike's motor system. This step requires professional knowledge and should be performed by a qualified ebike mechanic.
  4. Mounting: Attach the caliper to the frame or fork using post-mount adapters if needed. Mount the rotor (2.3mm thickness only) to the wheel hub.

Compatibility:

  • Rotors: Compatible only with 2.3mm thick rotors.
  • Mounting: Features 4-piston post mount calipers.
  • Ebike System: Requires a compatible ebike motor system for the cut-off function to be utilized.

Care:

  • Cleaning: Regularly clean the caliper, rotor, and pads with a degreaser and clean cloth. Avoid using harsh solvents on the rotor or pads.
  • Pad Wear: Inspect brake pads (Q13RS resin) regularly for wear. Replace when the pad material is down to approximately 1mm.
  • Fluid: The system is an open design, allowing for fluid top-ups. Use only Tektro-approved mineral oil.
  • Lever Adjustment: Adjust lever reach as needed using basic tools.
