Suspension, Brakes, Tires & Wheels - noise on breaks

i hear a wierd gratting noise when i apply my breaks (more frequently when it rains/after it rains). i heard its just dust brakes and its common especially with cars equipped with abs - is this true? what about a high pitched noise when you apply your brakes? does it mean that your breaks are thin? thanks.

it means that your brake pads are getting low and will need to be changed soon. The put little pieces of metal in the pads purposly, that way when its low they make that noise telling you that they need to be changed.

If you hear a grating/grinding noise, you're cutting into the rotors. If its a high pitched squeek, it's time to change the pads or have the rotors re-surfaced.

Check your brake fluid. If it's low then your brake pads need to be replace.

do a visual to check your pad thickness. If it looks okay it may just be the brake dust you were told about. This is more and more common in the newer metalic pads that are sold today. My freind had brake noise that sounded like he needed new pads. His were okay. I soaked his pads with brake cleaner and had hime drive around the block while riding his breaks (twice) then his break noise went away. But thats only if our pads are still good.

Lol, i was thinking the same thing!! Brake fluid doesn't really affect the brake pads. Brake fluid is used to pressurize the braking system so that your brake pads will be able to squeeze the brake disc hard enough to stop (or slow down) the car.

Edit: Man, I just looked back at that post and it is like FIVE MONTHS old!!! Death Before Decaf, pay attention to the dates on the thread before replying. Thanks.

the fluid will be a little low because some of the fluid will be in the caliper holding the piston farther out. i dont know how reliable this is as a check though.

that difference is so miniscule.. you will lose more braking power from the brake line flex (on most stock cars) than if your pads were low... totally no need to worry about brake pressure drop from worn pads.

i dont think he meant pressure drop, its that the level will be a little lower because the fluid is in the calipers instead of the resevoir.

Well, the brake fluid level in the resevoir will likely not drop by a noticable amount. Unless you measured it when you put new pads in... but seriously, this is not a good way to check brake pads anyway... just take the wheel off and look... that is the best way.

I don't know about the gratting noise, but if your breaks are squeking then you'll more than likely need new pads

The wear indicators are designed so that when your pads get worn enough, they will start scraping on the rotors (not damaging them). BUT they will make a scraping noise ALL THE TIME, NOT JUST WHEN YOU'RE BRAKING. Don't try to determine your brake wear level simply by how much brake fluid you have. The best thing to do is just to check them. Make sure you check both the inside and outside pads, though, because often times they will wear differently. One cause of scraping could be small rock(s) that often get kicked up and get caught in the caliper. When you do your once over of the pads, check the rotors, since you may need to have them turned.
