Oh, Tektro E10.11! That explains it. They've got stuff added to make them last longer. If you buy pads that don't last as long, that could solve your problem!
I thought that they were "soft" pads because they're not metal pads ?
I've wondered about grit. Maybe in damp weather, it could stick to the rotor, than get stuck in the pad.
This s*it is like multi-grit grinding paste,..
Even airborne dust and grit gets tossed up into the grinding/chopping blades of the rotor.
I see the wear on your rotor extends to the edge on the right bit is a couple of mm short on the left.
Yeah the pad isn't centered properly and is extending past the braking surface and into the spokes,..
Ohh,.. for reference sake, the rotor is ~1.8mm thick.
I've got my camera all zoomed in so the lip looks huge.
Suppose a squealing sound wakens you at 3 AM,.. it's your extended life Tektro pads.
My brakes have never made any noise.
Interestingly my first e-bike would ring like a bell when I applied the front brake.
The fender would ring like a symbol on a drum set with the vibration from braking.
I didn't need a bell.
I could tap the brake and ring my fender.
I decided that it was annoying and jammed little pieces of rubber into the fender braket attachments and that stopped the ringing.
A bit like you guys and your bell, but in reverse.
You've got to get those pads out
It looks like you've got the same rotor as I'm getting, and the same caliper too ?
What brake pads are you using ?
From what I gather regular pads are dirt cheap but wear out fast.
I don't care about that, I just don't want to wreck my new rotor.
That box with 4 sets of pads and tools is eleven bucks now, but it's got chunks of ropes, and metal in them, maybe tree bark too ?
Do you need more brake lever pressure with "regular" pads ?
