I have an Tektro Auriga Comp Hydraulic Disc Brake System. It's been running worry free for ~10 years.

But now I need to replace the rear disk brake pads (for only the second time). However the 3mm allen key holding the pads in place had rounded off. i.e. Meaning I could not take it out with an allen key. Instead I had to drill it out with a bolt extractor.

I'll need to replace this bolt but I'm not sure what it's called.

enter image description here

Does anyone know the name of this bolt? Alternatively can it be replaced by a different type of bolt?

    I’m amazed you only needed to replace the pads twice in 10 years.

  • I would have expected to change them more. I also expected to change the Hydraulic brake oil every 2 years. But I've never needed to do that. When the brakes felt sponge I checked the pads, noticed they were low, replaced them, and that fixed the issue.

  • Technically you do really need to replace the fluid through a proper bleed process after 10 years. Tektro uses mineral oil I believe which does not absorb moisture. This means there is likely some water sitting in your calipers which will boil if you get in a heavy braking situation an heat the calipers up a lot. Personally I'd have them bled for peace of mind.

  • I was unaware of that. I assumed I'd feel the difference. I already have the parts and it looks fun to do. Good suggestion.

    As there is no load on the pin, you could use a split pin for retaining the pads. (Many brakes do, some Shimano come with a split pin but have threads in the caliper for a retaining bolt)

This part is generally called a "brake pad retaining bolt" or often only "retaining bolt". They differ between brake brands and sometimes models, but a quick search for your brake model and "retaining bolt" usually turns up the right part.

You’ll need to get the correct part from Tektro. I believe Tektro calls those bolts a ‘pad axle’. They have a parts list pdf that you can download from their website. If you can’t find your model calipers there you can probably find a contact email address or phone number.
