car squealing when I press on brakes

[Semidevil]

so everytime I start to brake, I hear a pretty loud squealing sound. I thought it had to do with my brakes.

I went to hibdons, they checked it and told me that my brakes are still good, and they cleaned some dirt out(no replacement). The invoice states my front are 25% worn and back are 60%.

I start to drive it again and the squealing is a lot softer, but I can still hear it. They said they dont know what could be the problem as brakepads are still good.

any body have idea what it could be??

02 nissan.

Use WD-40 on the surfaces of all of your rotors.

Maybe the rotors are glazed.

Back up at about 10-15 MPH and hit the brakes pretty hard, repeat 2-3 more times. Sometimes that is a quick fix

Oh FFS, this is why you don't ask for car advice on ATOT.

Squealing is usually caused by vibration between the back of the brake pad and the caliper, not the pad and rotor. Often brakes will start squeaking after a pad change, because a careless mechanic didn't put in the metal shims between the pad and caliper. To stop squealing, the best method is to first replace those metal shims if they have been thrown away, and when you are changing pads always apply some grease between the pad and the shim, and also between the shim and the caliper.

What? It will stop the squealing, won't it? I try to help people and this is the thanks I get.

I recall a thread on an automotive forum where someone put the anti-squeal on the entire rotor and then posted a question asking why his car was smoking. :laugh:

NO, it absolutely will not. As I said, in the vast majority of cases the squealing is caused by vibration between the caliper and the back of the pad.

You may have a small piglet stuck under the brake pedal. This is typical in Nissans.

Jesus you can't say things like that! Some people are stupid enough to actually do it and may think you're being serious!

You could get someone killed!

Do you know what you are talking about? Or did you just think it was cool to join the bashing?

Err... was it supposed to be a joke? Coz I don't get it - applying WD40 to your brakes would do nothing but make them smell bad for an hour. WD40 is a weak lubricant, it would be wiped off the rotor the first time the brakes were applied. There is no danger here.

will not doing anything for now cause any harm for the vehicle or danger to me while driving???

 

[iamaelephant]

No it's fine to wait until your next pad change or just ignore it all together.

probably not. It's actually pretty common to have brakes do that, provided we are thinking about the same sound.

You should be fine.

If you are THAT worried about it, then just have your brake pads changed again... but it will be a waste of money.

If the car smells like burning brake pad, the brake light comes on, or you notice excessive brake dust on your wheels, then you should have it checked out.

A lot of times the squealing can do with the moisture content in the air. If enough settles on the rotors/callipers, this can cause squealing. It happens all the time in my neck of the woods during this time of year when the temps hover around freezing for a few weeks or a month. When the ice melts and evaporates, the air gets humid around here and everyone's brakes squeal a little. At least for the first few blocks.

A quick temporary fix is to press down quite hard (but don't slam) on the brakes when coming up to a stop from maybe 10-15mph. I advise you not to do this when other traffic is around (like my ex - I think she gave a lady at an intersection a heart-attack because my ex slammed on her brakes to remedy the sqealing - lady thought my ex was going to run the 4-way stop)

Anyways, I hope this helps and is also the source of your problems. FWIW, I just got new pads on and the rotors re-ground and my brakes squeal right now tonight as I drove home.

Read the directions that come with the brakes. When I bought mine, I was told specifically by the Napa employee NOT to add grease between the pad and shim.

hmm. who shall i trust. is it bad that i put more faith in ATOT than a paid "Professional?"

he was probably playing it safe, assuming you would end up with grease on the pads or rotors. mabye. mabye i don't know what i'm talking about.

Some people think that it could cause a loss of heat transfer between the pad and caliper and cause the brakes to overheat. At a shop I used to work at we just used copper grease so it wasn't an issue. In any case under 95% of driving conditions it isn't going to be a concern.

This has been the case with my car. It only does it the first couple of times I use the brakes in the morning and sometimes after I get in it to go home for lunch (or when it sits too long in high humidity). I'm in Houston BTW. LOL

I've had my brakes checked out and they're fine. This is common around here.
