Brake squeal can come from various places. If you did not buy higher quality pads, you may have received pads with a high metallic content. While it makes the pads last longer you get that annoying squeal.
It could be that you did not have your rotors turned and some "settling" will need to occur and the squeal may leave after the are of the pad is worn down to match the rotor.
It could be that the adhesion of the pad to the caliper is off or allowed to vibrate. You can purchase a "glue" for the back of the pads that adheres it to the caliper and sometimes stops squeals. (in fact the stuff I am thinking of is called "Stop Squeal" its an orange type paste that is applied to the back of the pad that is in contact with the calipers)
Do you have multiple piston calipers? If so it could be that one piston is not applying enough pressure or that it is stuck and thus the pad is getting heavily applied on one side and not the other.
Its also possible that the metal break guard is in the way of the rotor and thus is wearing when the rotor turns.
Check your emergency break adjustment. Often there is a procedure for "recalibrating your breaks" which usually involves driving in reverse for at least a certain distance and often involves lightly applying the break while doing so.
That's all I can think of at this time.
Hope this helps

I take it the brakes are new. If you didnt change the rotor you should check it for uneven wear and deep groves. If there are large groves in it then you need to replace it(whick cost go from 10.00 to 100.00 a rotor) or have the rotors resurfaced which sometimes is not the most cost efficiant way to go about it but the rotor need to have enought meat on them to do this.
If your rotors are bad and you leave as is, the squeal might go away after time but you will probable end up replacing your pads sooner than you would want to.
If rotors are good then i would take it all apart and check for the aluminuim guides hitting the rotor . I would also go to your autoparts store and pick up some brake pad lubrication to put on the back of the pads to kill two possibilities at once.
Hope that helped

If you merely did a "Pad Slap" and didn't machine the rotors, chances are that you have pads that don't fit the deep wear pattern in the rotor. It is also possible that when it was reassembled, there is a mis-alignment of hardware or pads, or the assembly wasn't particularly clean. Dirt and rust flake cause all sorts of headaches for do-it-yourselfers ans techs alike. It is imperative that everything, particularly metal-to-metal parts (eg. caliper-to-bracket) be very clean and free from rust, dust and dirt.
Beyond these suggestions, it is pretty hard to advise you as I can't either see or hear what is present.
If the work was performed by a shop. it is incumbent upon the shop to repair the condition. Do it soon. Safety is a major issue, and the longer it goes in this condition, the less likely he is of making any adjustments for you.
Good Luck

your brake shoes are probably worn down the squeal is the metal part of the brake telling you it's in need of new shoes.don't wait to long that squeal is gouging a groove in your rotor. i'm a mechanic

it fairly is in simple terms about easily a seized caliper piston, not unknown on Scenics (renaults) you may desire to strip the pads out on the two components and verify they are not worn to the metallic, chip off each and all of the rust from the discs, clean and cord brush each and every thing. carefully push the pistons precise back and verify that the sliders at the instant are not jammed. Refit the pads or extra healthful new in the event that they are US. Smear copper ease grease at the back of the pads (not braking area) and re convey mutually the calipers. Get somebody to press and launch the brake pedal. the disc might desire to turn freely with the pads in simple terms touching. in the event that they are nonetheless sticking you may wreck out with bleeding them or you like new pistons and seals.

If your vehicle has some age on it, the rotors could be worn and need to be turned. But whoever put your new brakes on should have inspected the rotor's!!

Disc brakes have a sensor, when the pads are worn down the sensor starts hitting the disc when you apply brakes to prevent the disc from being damaged it is an excellent time to get a brake job.

It may be one of two things, one, your break pads have an "alarm" on them to tell you when they are getting to thin and are in need of replacing, or two, they may be a newer style of pad that contains more metal in them. It is also possible that you have like sand stuck in them, doing and emergency stop should rid you of the problem by embedding the sand or dislodging it.

IT COULD BE A HARDER COMPOSITION OF BRAKE PAD DID YOU HAVE ROTORS RESURFACED OR REPLACE THEM IF NOT THEY EILL HAVE A GLZE BUILD UP THAT COULD CAUSE A SQUEAL OR THE SHOES OR PADS ARE CONTAMINATED WITH SOMETHING

sound as tho your brake pads are worn out and you are metal to metal
