Why are my brakes making a squealing noise?

Almost all disc pads are impregnated with metal particles to make them last longer.

Give the brakes a month to get seated properly with the brake rotors.

DO NOT spray anything on them.

The problem subside and you will be annoyed No more.

DRIVE SAFLEY !!!

You can tell by the wide variety of replies that there are several theories on this.Some new and some old brakes will squeal at certain times.There are things to do to try to eliminate this.Probably for now,go back to the shop and talk with them about this because it's their problem now.

you're in want of brake artwork. the disc pads on your brakes are wiped out ,and at the same time as this happens there are countless troublesome metal pins that come out of the pads and make contact with the rotors.at the same time as this noise 1st seems audible it truly is time to interchange the pads.if enable flow too lengthy the noise is consistent and the pins placed on grooves contained in the rotors,and the rotors must be grew to develop into on a lathe or replaced it is amazingly usually the most potential answer. desire this helps. ken

When the brake pads are changed, they should have turned the rotors to remove the glaze.

When new pads are installed without the rotors being turned,

the pads will glaze over and cause a squealing.

Have the rotors turned and then take 150 grit sandpaper and slide the pads over it a

few times to remove the glaze from the pads.

By doing this, the squealing will end and you will enjoy hitting the brakes again.

Good Luck...

they could have put hard pads on it, it could be brake dust or a caliper hanging up. get some brake cleaner and spray the rotors to get rid of the brake dust. or you could just spray your wheels with water. i did that before to get rid of the brake dust.

Tire black an oily substance if accidentally gotten on the brake discs will make them squeak even with new pads.

It could be that they have not had time to wear in yet or some dirt has got into them. If the pads were renewed you should check with the garage.

Take it back and tell them what going on, or your brake are wet (did it rain?) if so then they are wet, give it time to dry, otherwise take the car back and tell them..

Get some copper grease on there. That will stop it.
