Sqeaky brakes/wheels

[zaven]

So my brakes sqeal quite a bit when cold, and sometimes there is even a repetitive sqeak when the brake's aren't applied (at low speeds when cold)

I had the brakes inspected, and they have over 50% left. It looks like the rotors are just rusty or something, so it sqeaks. I don't want to pay a bunch of money for a brake job if it isn't needed yet. What can I do to get rid of the squeaking? I heard there was some kind of spray you can buy at the store... any thoughts?

thanks

There's a couple things you can do. One is a spray that oges on the back of the pads. This is an adhesive that helps reduce vibration of the pad and also makes the pad stick to the caliper. By sticking to the caliper it will prevent the pad from constantly contacting the rotor. Contact with the rotor all the time will cause noise and increase heat.
Keep in mind though that this is an adhesive specifically for the back of the pad and NOT for the side that contacts the rotors.

There's another fluid that can be rubbed on to the actual pad material itself. This soaks in to the pad and again helps to reduce noise.

The brake pads in use on our cars are semi-metalic. This means that part of it is metal. Metal on metal is going to create a noise almost no matter what you do. If you've got rust on the rotors or drums then you're going to have a noise from that as well.

The source of the nose could also come from the pads and rotors themselves. Grooves that form from the two materials being pressed against each other can be the cause itself. Noise is simply a vibration that we can interpret by hearing it. The noise or vibration is always there but it changes to a frequency that we can no longer hear and so we don't try and address it.

You may be able to remove the rotors and pads, take sand paper to the pads and lightly scuff them up. You can also take your rotors somewhere and have them resurfaced. By doing this you will get rid of the two surfaces that were causing the noise in the first place.

Yea i have the same problem. i had old pads and really bad rotors and it squeeked all the time. i just got new pads and new rotors about a month ago and it still does it. when im braking and sometimes when im not. could i have those same problems?

GS you problem may be the type of pads used. Some are just noisier than others and there's not much you can do other than replace them with a different brand or style.

You may also want to check the rear pads/shoes as well. I've run in to a couple of vehicles where the noise sounds like the front but actually coming from the rear. Just something to think about and maybe check out.
