Told the brake pads are shot, how do I tell?

Finally got around to this job with the help of articles and information on this site. Took me waaaay longer than it should have because I’ve never done anything close to this before. Got it done though!

Here’s the before and after pics on the rear, now I see the difference.

Thanks everyone for all the help!!!

Good job, now go back and correct the fitment on the rubber boot on the rear guide dowel (its not seated correctly)

Just pulled my rear wheel for a tire replacement.

I'm no expert, but am I correct that I have plenty of life left in these rear pads?

Yes, easily 70% or more left.
