Thanks for the replies. I have reviewed all in detail.

To reply to the previous posts:

I have replaced the guide mounts shown in WBain's post, twice since I owned the car, and this is not the same symptoms as when they fail. And to add life to them, I suggest ensuring the boot is sealing properly keeping dirt out the this part.

The pads are Pagid brand. Prior were ATE.

There are no kleen wheels installed.

Last night I went by the shop. The mechanic was walking back from the brake shop across the street, with my freshly turned front rotors in hand. These were new 50 miles ago. The shop supervisor was confident this was the problem, and he assured me he will put everything together in the morning and call me after test driving the car. I instructed him to put the original caliper back on the car, and put everything back where it was when he started. I intend to go get my keys and get the car out of the shop today, and get it away from him.

I will update when I get the car back. I am leaning toward caliper or brkae lines maybe? I have experienced a caliper sticking due to a collapsed brake line on another car. Perhaps this is the case here?
