When i press the brakes on my car i hear a squealing sound.. What could be wrong with it?

Question

I had my brake pads looked at and there was nothing wrong with them.. what else could be causing the squealing noise??

Answer 1

I have had this problem with dirt getting in between the pads and the drum, or when they get wet. If that isn't the problem, maybe getting better quality brake pads would fix the problem. My advice to you is look into the cheaper things first. Good Luck!!

Answer 2

Since your pads checked out OK then it's just a typical pad squealing noise. They sell anti-squeal products that the mechanic is supposed to put on the back side (metal) of the pads before installing them. Some companies sell new pads with "anti-squeal" shims which is just a very thin piece of metal that goes between the caliper and the back of the new pads.
The noise is caused by the vibration of the pads when you are braking. The pad has a solid steel back that butts up against a caliper piston that is typically stainless steel. When you step on the brakes the pad material raises the surface temperature of the brake rotor to very hot very fast. The brake pad material begins to vaporize as it grabs the metal rotor and all of this creates some dramatic heat and the vibration is created by this pressure. Like a small fight is going on where the pad wants off the hot surface because pressure is pushing it back but you are standing on the brake pedal and the pad can't jump off that hot surface so all it can do is vibrate ever so slightly but probably several hundred vibrations per second and all you hear is "sqeeeeak".
The best anti-squeal compound I've used is made by Lock-Tite and is blue in color and thick like toothpaste.

They will have to pull the pads off to apply this and then put them back on and that should be that.

Answer 3

STOP. do not replace your brake pads. i've seen this and heard this before. a person can go through several different brands of brake pads but will still get the squeak.

a person can try anti squal compounds up the yinyang and still get squeak.

You are always gonna get squeaks if you own a car that's over 5 years old, or if it's an American car of any year.

You are always gonna get squeaks if you have to use the brakes in traffic and the summer is almost here.

there is only one solution: you must coast to a stop and keep off the brakes all the time. accellerate your car like a total grandmother and never floor the gas pedal ever. Let everybody just pass you and live with it. The bus in the slow lane is never on the brakes because he is slower than everybody else.

Answer 4

Squealing is caused by metal scraping on metal. You have a wear sensor scraping on the rotor (worn brakes) or a brake pad scraping/moving/vibrating within the caliper. Get it in and have them look again. Have them drive the car so they hear the noise.

Answer 5

the squealing noise is coming from the brake pad rubbing on the the caliper. what needs to be done is have brake lube put on the back of the brake pads

Answer 6

cheap brake pads. go buy some better brake pads and have them grease up the caliper slide pins when they do the brake job. I suggest ceramic pads or Bendix Original Equipment pads, which you may purchase at Advance Auto Parts for between 30 and 45 dollars...

Answer 7

I have the same thing...I was told the pads get crystallized and they squeal...if the sound is coming from the back it is probally your brake shoes! Hope I helped!

Answer 8

chances are that you have a hard pad on the car. life time pads for instance are a hard pad, so the manufactures use a hard composite brake material. i would recommend resurfacing your brake pads, if this does not help, you can replace pads with ceramic pads. this will also give you better breaking. good luck!

Answer 9

More then likely your breaks are worn down and you need new ones. Although it could just be break dust. Your best bet is to take it in and have them look at it. I would have it checked out soon though because if the breaks are worn down then the metal of the break will start diging into the rotor and then you will either have to pay to have that filed even or buy a new one. Good luck.

the element with the locks replaced into occurring with our automobile, we had to have each and all of the electrical powered stuff interior replaced. The sprint lights have been additionally dimming out and weren't on the suited colour. the front tires i'm uncertain of.. yet with Chryslers this happens plenty. while they arrive from the production facility all of them have that sound till that's some how fixed by technique of a mechanic.
