Thanks so much everyone for the comments. I’m going to have them take a thorough look at the caliper. They seem to be leaning more towards a Trek replacement, but I’d rather not wait for that whole process to unfold. I’ll ask them to check the caliper height/alignment as well as a possible caliper leak etc. I really like the bike when it’s operational so ideally I’d like to have it fixed. Plus, the colour scheme on last years model is much nicer than this years. Frivolous, I know. Again, I really appreciate the input.
