My brakes were squeaking and it was getting annoying! I think when I worked on the brakes at the dealership these guys didn't overapply or use really cheap quality lube. When I removed the brake pads myself, there was no lubrication. I've applied this around the brake parts and it works great! No more creaking. Like new. I'm sure this little package is enough to do all 4 brakes and more depending on how much you apply.
