Tektro HD-E350 - Disc Brake

No, the Tektro HD-E350 features an EZ Plug-In system and comes pre-bled and pressure tested. No bleeding is required upon initial installation.

The Tektro HD-E350 is designed for use with disc rotors that are 1.8mm thick. The diameter of the rotor (e.g., 160mm, 180mm, 203mm) will depend on your eBike's frame and fork compatibility.

This brake comes equipped with low-noise resin (organic) brake pads. While metallic pads may fit, it is recommended to use resin pads for optimal performance and to avoid potential damage to the caliper or rotor, and to maintain quiet operation.

The Tektro HD-E350 uses Tektro TRP mineral oil. It is important to only use mineral oil and not DOT fluid, as DOT fluid can damage the seals.

The brake is sold as a Left or Right hand set, corresponding to front or rear brake installation. The lever itself is not designed to be easily swapped between sides without re-routing the hose.

The brake includes two sensor cable connectors. You will need to splice these into your eBike's existing motor cut-off wiring, ensuring a secure and waterproof connection.

Tektro states that all parts are available as spares. You can typically find replacement parts through authorized Tektro dealers or online bicycle component retailers.

While the brake is pre-bled, air may have entered the system during installation or if the system was compromised. Check hose connections for leaks. If a spongy feel persists, a bleed might be necessary using Tektro TRP mineral oil and appropriate bleeding tools.

Verify that the motor cut-off wire is securely connected to your eBike's corresponding wire using the provided connectors. Ensure the connections are clean and free from corrosion. Check your eBike's wiring diagram for correct integration.

Ensure that the brake pads and rotor are clean. Resin pads can sometimes become contaminated. If noise persists, consider replacing the resin pads with new ones or bedding them in properly. Check that the caliper is aligned correctly with the rotor.

Check the rotor for contamination or damage. Ensure the brake pads are not excessively worn and are properly seated. Verify that the caliper is aligned squarely with the rotor and that the pistons are moving freely.
