another product is "antisqueel" made by crc- comes in a tube, wurth also make an aerosole version that you applicate to the back of the pads.
You can also get a file and file the leading corners (not too much) off the pad material. Use copper grease sparingly to lightly coat the brake pins.
Make sure your rotor isn't overly worn as this can also be the reason for noise- if so replace with new....

hope this helps.
