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?
