Tektro brake pad identification

Read the complete HD or MD model code on both calipers. Match each code to a group in this guide, then compare the old pad outline and the specified new-pad thickness. Range names such as Orion or Dorado do not identify one universal pad.

No. Orion HD-M735 uses the standard four-piston shape at the front and the standard two-piston shape at the rear. Gemini HD-M530 uses the 5 mm four-piston pad at the front and the 5 mm two-piston pad at the rear. Identify each caliper separately.

Use the specification for your exact caliper model and the selected product. Q13RS identifies the 5 mm four-piston option; P21.11 and E11.11 identify the 5 mm two-piston option. Check the selected product’s compatibility list rather than choosing thickness by appearance alone. A worn pad measurement does not show its original thickness.

Dorado HD-E710 uses its own pad shape, referenced as D40.11. Choose the dedicated HD-E710 group. Other Dorado models appear in different groups and should not be selected by the Dorado name alone.

These flat-mount calipers use the shape shown in the HD-R290 / HD-R310 / HD-R510 group. Check the complete caliper model and compare the pad outline before choosing a compound.

Check the selected product’s pack contents. If a pack covers one caliper, you need two packs for both brakes. Confirm both caliper models first, especially on systems with different front and rear pads.
