Disc brake pad release allen bolt 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.



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