Sounds like you might have some baked on brake dust on your linings. Some BMW's exhibit this noise quite a bit and BMW recommends this: Find a fairly deserted, dry road and run your Max up to around 50mph and apply brakes with authority until you slow down to 10mph or so. Do this about 5 times in a row. This will get the brakes very hot. Then see if the squealing goes away. If it does then you just scraped off the burned residue baked on to the pads in a more vigorous manner than your tech might have. I've done this with a few of my cars with good results. If this does not work then take her back in for pad replacements on both fronts. Make sure your tech cleaned the back of the pads as well as the faces. If you do this yourself then I would also apply a light coating of silicone grease to the rear of the pads where they touch the calipers. Also clean and apply lube sparingly to the part of the caliper piston that pushes against the rear of the pad. Since I have started replacing my own pads I have NEVER experience break squeal. What I do is clean and lube the caliper "slides" and clean and lube all surfaces where the pads touch the calipers and piston. I use high temperature silicone grease for this. Use sparingly. Good luck. I understand how much break squeal can ruin a nice drive.
