someone on here just had this problem on their rear discs so it was fresh in my mind but when he says "there's air trapped in the top of the caliper" was kind of a clue. i'm glad nobody records the dumb stuff i do.
I'd never take my car or truck to those old timers. Looks like they have a nice shop, but failed to figure out "the real problem". Instead, they went around the problem to correct it. Which means, next time the calipers have to be replaced, it'll happen again.
