Tektro HD-E350 E-Bike Hydraulic Disc Brake Set

Name: Tektro HD-E350 E-Bike Hydraulic Disc Brake Set
Brand: Tektro

The HD-E350 is one of the most common hydraulic brakes fitted to e-bikes as original equipment, and it is sold as a complete front/rear set for upgrades and replacements. What makes it e-bike specific is the lever: it includes a motor cut-off switch with a lead that plugs into most controllers. The two-piston calipers, pre-bled hoses and resin pads are the same proven Tektro recipe used across their range. It is a meaningful upgrade from mechanical discs on a heavy bike and a direct replacement when an OEM Tektro lever or caliper fails.

Tektro E10.11 Disc Brake Pads

If a budget or mid-priced e-bike has Tektro brakes, there is a good chance it takes the E10.11 pad: it fits many Tektro hydraulic calipers as well as the common Aries and Novela mechanical calipers. Tektro sells the E10.11 in resin/organic compound, and aftermarket makers offer semi-metallic and sintered versions in the same shape. Resin is quiet and bites quickly; metallic lasts longer on a heavy e-bike but can be noisier. Confirm the pad shape by checking the part number stamped on your old pads or by matching the outline before ordering.

Mineral Oil Hydraulic Brake Bleed Kit for Shimano/Tektro/Magura (generic)

Bleeding hydraulic brakes at home is a reasonable job for an e-bike owner, and the generic bleed kit makes it possible: two syringes, hoses, a bleed cup and a bag of adapters that thread into Shimano, Tektro and Magura levers and calipers. Most kits are sold with or without a small bottle of mineral oil. It pays to get a kit that includes the Shimano funnel and the M5/M6 fittings for Tektro calipers, since those are what most e-bikes have. Follow the manufacturer's bleed procedure; each brand differs slightly.

Best for: Owners of Shimano, Tektro or Magura mineral-oil brakes · Fixing spongy levers or after shortening a hose · Riders who want to do annual brake maintenance themselves

Brake Rotors

Shimano SM-RT56 180 mm 6-Bolt Disc Rotor

The SM-RT56 is Shimano's workhorse 6-bolt rotor, found on piles of entry and mid-level bikes and sold everywhere as a replacement. The 180 mm size is a good match for the front of a commuter e-bike and is what many 160 mm-equipped bikes upgrade to for more stopping power. One important detail: the RT56 is specified for resin pads only, so if you run sintered metallic pads you should choose a different rotor. It is a plain stamped steel rotor without a cooling fin or alloy carrier, which is exactly why it is inexpensive and durable.

Best for: Replacing a bent or worn 6-bolt rotor on an e-bike with resin pads · Upgrading a front brake from 160 to 180 mm (with a caliper adapter) · Riders who want a Shimano-quality rotor at a low price
