The "anchor pins" allows the caliper to move. The pads themselves move in the bracket guide/rail whatever you call them.
In the following, you can see the pads sit in the bracket. The caliper clip over the pads.

You know, if they weren't squealing before somebody worked on it, then it doesn't say well about the mechanic. But to be fair, it could also be the caliper not retracting properly. If that's the case, then you need to check the operation of the anchor pins (see if they slide easily with finger pressure) or that the piston retracts correctly.
One TN member (?) suggested pushing the piston in very slightly and see if it returns to the previous position. Don't remember if he used a plier to pull it out slightly (don't scratch the piston).
Also, if there is air in the lines and it heats up, then my guess is that the brakes will apply (even slightly). So have they changed the fluid and bled everything? And I hope the brake hose wasn't so old that it's falling apart inside, creating an effect of a check-valve and such.

What are and where are the anchor pins and bracket rails located? Thanks for your inputs guys, I really want to narrow down the cause of the noise so that I wouldn't end up with an expensive repair bill...
