I have been to a few different mechanics and nobody can figure this out...
My brakes sqeak and grind a lot! I have replaced all brakes and turned all rotors a few times thinking I had gotten a bad set, yet they still continue to sqeak and grind. Lately I have also noticed that when I brake and the car comes to a stop, the car rocks back and forth more than usual. Any suggestions before I waste more time and money for nothing?
I have a 2000 Toyota Corolla if that makes any difference.

You may need to replace the wheel bearing.....

Most often the noise you hear from your brakes, in disc brakes, is the pad vibrating between the caliper and the piston that applies pressure to apply the stopping force. There are lots of really good compounds on the market that minimize this noise but in a lot of cases the type of pad and the type of rotor get miss matched and you end up with brakes that work well but are still a little rough on the ears. You may talk to your mechanic and ask if there's a different pad that could be used to help the situation. As far as the car rocking back and forth there is a little bit of movement in these systems but I might suggest you take more space and time to stop more smoothly. This will provide you with more safety and your brakes will last a great deal longer. Hey, I just had the thought that if you are experiencing this kind of rocking going on. You are probably not giving yourself proper room to stop. When you stop fast, short and hard like you are most certainly doing this causes a great deal of heat build up in the brakes and stresses the components, glazing the pads and rotors. Most certainly you will get noise.

Well, if I were guessing I would guess you had a frozen caliper which might account for the grinding. If that were the case it might be holding the pads in contact with the rotor and account for the squealing as well when they overheat. I would look for some bluing or scortching on the rotors as a means of diagnosing if this is the case. You might also pull the pads and see if the surfaces are glazed.
You may also have used metallic pads which have a tendency to squeal, but that would not account for grinding. Are you sure the grinding is not a wheel bearing or a c/v joint. Is it front or rear that you hear this?
Please feel free to write to me if you wish to pursue it at greater length.

I am assuming you have a warranty where you got the brakes done. Alot of shops put the cheapest brakes they can purchase on there. I would invest in some bendix ceramics, turn the rotors, then have the wheels torqued to specs afterwards, you can do the best brake job in the world but if you use an impact gun to tighten the wheels when done without using torque sticks, then it's a wasted brake job.

Toyota's come from the factory with organic brake pads. They last between 60,000 - 80,000 miles. Who ever did your brakes used semi-metallic, full metallic or ceramic pads. You may be able to fix this problem by removing the brake pads and cleaning the steel non-friction side with CRC Brake clean. Spread a .090 thickness of CRC Brake Quiet on all four of the steel sides and let them dry for 30 minutes. CRC Brake Quiet is a high temperature silicone harmonic sound deadening insulator. Reassemble the pads an your problem will be solved. Keep in mind full metallic or semi-metallic brake pads are absolute he*l on brake rotors.
If you don't like the plan of putting the super abrasive, noisy, dirty metallic pads back on there are several companies who sell organic based brake pads. If you ever noticed Toyota aluminum wheels are always super clean. That's because of the organic based pads. EBC Green Stuff is one. the standard Toyota pad is another.
Make absolutely all four (2 per wheel) slider pins are smooth and greased with synthetic brake grease.

i belive your job was not done right the 1st time.
when turning them rotors lot of cleanning is required to get the steel dust off them which is caused by turning on the machine, prior to fitting them back on with new set of pads.
and try not to use brake pads which are too hard use softer quality pads and all moveing parts should be clean and all sliders greased and make sure pistons are moveing freely in the calipers. Most brake pads would have steel backing plates which also fit with the pads and suitable lubricant is used so the backing plate dosent squeak when brakes applied

When you first replaced the brakes was it because of this condition? Go to the dealer and purchase a new set of pads and rotors.

what kind of pads did you put on, sometimes they will sqeak for awhile and some of the cheap one will always.
