Can a hydraulic brake line have invisible damage?

That reminds me... The OE were resin.
I ordered semi-metalic to see if I liked them.

IIRC, you and I have the same Tektro brakes?

I've only ever used the OE Tektro brake pads,..


This is what I found out about the OE brake pads,..

Sounds like they're semi-metallic resin pads??

You can see all the chunks of copper and bullet proof fiber in the pad,..
