do new break pads squeal?
I just replaced my front brake pads with Mazda parts. I think I did everything right, but them damn new pads squeal like skinny white boys in a State prison when I brake. I think I put in those little anti-rattle springs in correctly, but I didn't use any of that glue that glues the pads to the caliper....do new pads take a while to "break in?"
Right on.

i won't be getting used to this squeal...it is damn loud...I'll give it a week to let the pads break into the rotor but I guess I'll see what that glue is all about after that. Any other thoughts.

you should install new pads with the grease that comes with the pads,,the grease helps stop that noise..just
add some grease on the rotor,,not much,,, since you
didn't put it on the pads..

brownmound - get yerself some of that anti-squeal stuff and put a dab between your pads and the backing shim. Also, take a file and chamfer the edges of your pads about a 1/16" of an inch to take the sharp edge off the pads. When putting the pads back in, grease up the back of the pads and make sure that the caliper slider pins are well greased too. The caliper should move on that pin freely otherwise it can bind up and cause squealing, uneven wear on the rotor and reduced stopping power.
Good luck!

I can't believe someone actually told him to put grease on his rotor
that's kinda dangerous.. THAT is why people shouldn't give advice if they don't know what they're talking about.. not to rip on you man, but he coulda killed himself.
By the way, if you do get grease or something on your rotors, wipe most of it off then take some brake parts cleaner and I think it should come off, wipe it again, etc..

New pads can squeek for a while, especially if they are semi-metallics. I always buy the cheap organic masda pads - very quiet and very cheap (about $20 Canadian). As mentioned above, once the hard edges wear a little, they should quiet down. BTW, I have never greased the back of the pad, just the caliper pins - I'm not clear on how the back of the pad has anything to do with squeeking brakes - can anyone jump in and explain that one to me??

Greasing the back of the pad helps keep the pad free-floating and less likely to bind and cause a squeak. Or, at least, that's what I figure........
BTW I only only use a very little bit of grease on the back and my brakes never squeak.

Semi-metallics squeak as a function of the materials they're made from. He used factory pads, but his mistake was not using the goo. It's not glue. When the pads touch the rotor, it generates wave-forms that turn your metal-to-metal interface between the pad backing and caliper piston face into a sound machine. That's where the high pitched squeal is being generated if it's not from the "worn pad" pin that contacts the rotor when the majority of your disc pad is used up. The goo absorbs the oscillations and converts it into heat which is a form of energy that can be dissipated by the metal caliper piston and brake fluid...

The pads do move ever so slighlty during braking, therefore the high pitched noise. The metal backs moving against the piston face. For a test, when you're slowing down and hear the noise, apply more pressure on the brake pedal and the noise will dissapate. The added pressure keeps the pads "secured" in a stationary position. Most solutions you apply to the backs, should actually dry before the pads are installed. This gives insulation between the pads and piston.

I always used that stuff you spray on the back of the pad (contacts the brake caliper piston) it glues the pad to the caliper so it can move side to side, always stopped the noise for me

the anti-squeal compound prevents the wave harmonics formed when the pad vibrates between rotor and caliper. It acts as a dampener, like engine mounts dampen vibrations.
The squeal from worn pads is often generated by a metal strip intended to squeal when your breaks wear down to low levels
