Weird noise Options

[jtmlb3k]

I've posted on this before but it turns out the suggested issue wasn't right. So for about the last 4 months my car's back passenger side break has been clicking/knocking whenever I press down to a certain point on the brake pedal. People on the forum suggested it might be loose bolts on my calipers, but I checked them myself and they were fine and then had my mechanic check them as well when I got a tune up last month and he said everything seemed fine. So I'm totally stumped. Could my caliper just be bad?

Another thing I noticed was that even when I'm not braking, if I go really slowly the same clicking/knocking noise appears, and that recently my brake pedal vibrates when I'm braking at high speeds. Could any of this be connected?

I'm trying to get this sorted out before I decide if I should get a newer car or not at the end of the summer so any help would be greatly appreciated

Something people rarely check -- the e-brake hardware. Most specifically, the pins and springs which hold the e-brake shoes against the backing plate. Lose tension on one of those and the shoe will bounce against the backing plate.
