FRONT BRAKE WEAR
I think there is something not quite right with your LEFT caliper ...... At 23,000 mi. my front pads were not even HALF worn ( I have 38,00+ and the pads are ok ) ..... since your RIGHT side pads look good ......the LEFTside definitely has an issue that I think you need to deal with or the same thing is going to happen with the new parts ....jmho ....

I agree that something is not right there......but not having a complete explanation of what parts came from where makes for some guesswork.
IF.....the thin, burnt pads came from the same side.....where the rotor also looks burnt......then you have some kind of a problem with the caliper on that side. It might be the caliper itself or something in the system might be holding pressure there when it shouldn't.
You definitely should NOT just replace the rotor and pads without finding out what caused the excessive wear.......or you will just be throwing your money away. And on a hard stop, the fronts might not work right either. Could be dangerous.

Thanks Mike and ER. That's what I was thinking and have an appointment to let my favorite local Spyder mechanic flush and refill the brake system, then test it out. Yes all teh worn/burnt components came from the left front and the right side looked normal with plenty of usable life left. I had just decided to upgrade to the EBC components since I'm heavy (260lbs), a lead foot that likes to fly fast to a quick stop at the corners requiring a stop.
For the Brake experts, is it possible the right side had air in the line reducing it's stopping power and pad wear? I gotta say I ride the RTL hard and brake hard over the last 15k since I bought it. It's never seemed to "pull" when stopping.

When a caliper sticks, it often pulls when GOING.
A pinched or collapsed hose can cause a one-way valve kind of action......allowing the caliper to pinch but not release.

Bound outer left brake pad
Update and probable answer to why my front left pads / rotor wore so much more than my right side.
I did get a BRP certified Can AM Spyder tech answer in person today.
Turns out it's likely that my left outside pad had bound up in the caliper and wasn't sliding properly causing the inner to make up the difference, causing it to wear much more than all the other front pads leading to it's demise.
My new pads were mounted with a little dab of grease where the back plate "fingers" and the central hole that slides on the pin. They seem to "float" nice when no brake pedal pressure is in the mix. The tech checked my brake fluid and didn't think it needed changing. (It might have been changed at the dealer I bought it from back in '16).
And to clarify the pics above
The 1st picture in post #1 shows my new pads (at top of pic) and only my left side pads, the very worn down to the back plate pad on the right.
Having done this myself now, I'll make it my annual spring pre ride maintenance to pop the tires and calipers off and check the pads and their ease of movement within the caliper.
I will also be checking the brakes after my 6k ride at the end of the month.
