Tektro HD-E350 2-piston hydraulic disc brakes, front and rear, with rotors

A complete hydraulic disc brake set for an e-bike: two pre-bled Tektro HD-E350 assembled sets (lever with the motor cut-off sensor, hose and 2-piston caliper with resin pads fitted) plus a pair of Tektro 1.8 mm rotors. The lever's sensor cuts the motor the moment you brake, so the assist never fights the brakes.

Kit includes

• Front: HD-E350 2-piston post-mount caliper with its lever, pre-bled (fitted on the right in Australia)
• Rear: HD-E350 caliper with its lever and 1900 mm hose, pre-bled (fitted on the left in Australia)
• 2 x Tektro 1.8 mm stainless Centre Lock rotors, 180 mm

Options

Rotor sizes: Centre Lock: Tektro 1.8 mm 160, 180, 203 mm. The kit defaults to two 180 mm (Tektro 1.8 mm); set that row to 0 and pick another size, or mix sizes (a larger rotor at the front is common). HD-E350 takes 160 to 203 mm rotors (the Tektro sizes we stock).

Fit-up parts, sold separately (linked here and shown with this kit): Tektro mineral oil, a bleed kit. Add what your bike needs to the cart alongside the kit.

This kit is the Centre Lock version - the same brakes with 6-bolt rotors are the 6-bolt kit.

Already have rotors? Untick them and the price follows the parts you keep. Every part in this kit can be deselected, so a bike that only needs one end, or already has the right rotors, is not charged for the rest.

Fitting notes

Australian convention: the right-hand lever works the front brake and the left-hand lever the rear; the sets are built that way. Most post-mount forks and frames take a 160 mm rotor directly; check your fork or frame's native size - a larger rotor needs the matching Tektro adapter only when the mount is smaller than the rotor (not part of this kit - reuse the bracket already on your bike, or ask us). The 1900 mm rear hose suits most frames; very large frames or high-rise bars may need a longer hose fitted and bled by a workshop. The lever's sensor lead plugs into the e-bike's brake cut-off circuit - check your system's connector before ordering (Tektro rates it 10 W / 200 V DC / 0.5 A). Service fluid: Tektro mineral oil.

Tune Cycles supplies and fits these brakes. Choose your options above; if you are unsure what your fork, frame or hubs take, ask us before you order.
