I also have a Priority Continuum Onyx and have been riding it since March 2023. I have put about 1000 miles on the bike this year. This thread is really timely for me. As I have notice that my rear brakes have started to squeak occasionally. Also I thought the brakes needed to be bled. So I brought the bike to my lbs and they looked at the bike. They said the brakes don't need to be bled as of yet, and also the brake pads are fine and don't need to be changed. Also for point of reference I have always had rim brakes not disc brakes.

You gave so much information about the bike in your original post which I didn't have. So thank-you for that.
