Brake squeal that is not related to worn parts is caused by vibration. Your rotor is like an Lp, it has little grooves in it that are in a spiral design, especially a freshly turned or new one. If you had brakes done and they didn't machine the rotors or if they machined them and did not finish them with a non directional finish you will get a squeal 99% of the time. The brake pads follow the grooves like a needle follows the grooves on the Lp the only difference is the needle has somewhere to go and the brake pads don't. They only move a microscopic amount and start over again and repeat this motion until you stop. So just to throw a number out there if your are stopping your car from 30 mph over a distance of 100 ft your brake pads might jump back and forth like 49,000 times thus creating a noise between the back of the pad and the caliper which sounds like a squeak when in reality it's a high speed high pitch vibration. The noise does not come from between the friction surface of the pad and the rotor. Do not spray anything other than brake cleaner on your rotors. Brake cleaner will not fix the problem, it might for the first couple of time you hit the brakes but it will come back. The disc brake quiet is a good product if used properly. On the back of the pads. If you had the brakes done recently you should take the car back to the repair shop and have them fix it properly.

I am guessing that you just had them done, by you or some one else, first : new pads from the parts store are not like pads that came on the car,(truck) if all is good with the installation, you may just have to drive it for about 25 to 50 miles, no kidding. I also presume that you turned the rotors? if not then that may be the problem. if you did turn the rotors then they may just have to ware themselves in., there are also different grade pads, some are harder than others(the more expensive being the later) so they will tend to make some noise, and should go away with driving. if all else fails you should be able to take them back to where you bought them and try another pair. good luck Dave

Squealing is when the pads are vibrating against the disc. When you got the pads, they may have come with some rubberized metal pads to go between the pads and the caliper pistons, or they might have come with some glue in a tube that you put behid the pads to glue them to the piston and stop the squealing.
If they didn't come with either of these, you can go to the parts store and ask them for a recommendation of what they have in the store, depends on your car's brakes.

WD-40 inside the wheels where the brakes are located

Have the rotors turned or swirl grinded. Bf is mechanic. Or cut grooves on the pad if a Toyota.

There's a product called Disc Quiet that you can spray on them. (There are also several similar products.) Try Auto Zone or a similar store. Probably even WalMart or store with automotive department. NO WD-40!!!

Chamfer the pads and anti-seize on the backing. Or go with an organic pad.

Replace them

Might ought to have them checked. Squeaking may be a sign that they are getting worn.
