Where do you spray anti squeal on brakes to get rid of squeak?
Disc "squeal" is almost always caused by vibration between metal parts of the brake system - usually between the brake pad backing and the caliper piston, and between the pads and the pins that hold them to the caliper. The majority of people think that the sound is a result of the pads rubbing against the rotor, but this is rarely the case.
Buy a good anti disc pad grease from auto parts store and apply the the edge of the caliper piston and the back of the brake pad - also place lubricant on the pins and where they make contact to the pads. don't go crazy, because excess could get on the rotor and cause braking problems. Keep the rotor and pad surfaces as clean as possible - if you get grease on them, spray a good cleaner such as brake clean to remove the dirt/grease from the pad and rotor.
Put it all back together, and you should be good to go. This fix has worked perfectly on many bikes over the years.
If you have a "squeal" when you apply the brakes, spray the anti-squeal spray on the rotor. If the brakes are "squeaking" when you go down the road, it's probably the caliper moving side to side on the pins. Remove the pins and apply synthetic brake grease on the pins.
Good Luck

I agree with Ocsled that the squeal is usually being made by something other than the brake pads against the rotor but it is initially caused by contamination on the rotor causing an uneven braking effect. Parts against each other just don't make noise because they want to. I don't know what type of Anti-squeal product you have. So, spray a little bit onto a scrap piece of metal and see how fast it evaporates. If it evaporate quickly, you spray it one the rotor and wipe it off. Some people don't wipe it but I use it just like brake cleaner.
Now, if it's lubricant type anti-squeal spray, you remove your brake pads and spray it on the back of the pads. Not a lot, a little goes a long way. Then put the pads back in.
Good luck

Take off the pads and sand them down a little,
