When I brake my car seems to make a sqealing noise? what is my car trying to tell me?

Answer 1

If your car's brakes are making noise, and you have no experience repairing them then get it to a reputable brake technician.

Brake systems equipped with screecher tabs usually make noise when you are NOT stepping on the service brake peddle. The are attached to one of the brake pads on each side of the vehicle. They are angled against the forward rotation of the rotor. As the pad wears, it comes in contact with the rotor and makes a noise, warning you that the pads are fairly worn. When you step on the brake, the noise usually deadens. Some pads have metal rivets that, when the pads are worn, will come in contact with the rotor and make noise when you step on the brake. Most modern brake pads are impregnated with metal alloys in the lining itself. Some times overheating of the brakes with "glaze" the linings and make them "slippery" (for lack of a better term), and this glazing can make such a noise. Furthermore, a simple build-up of eroded lining material can build up on the leading edge of the pad as it wears normally and cause a squealing type of noise. Other rarer, odd problems can occur as well. Some pads require a shim between the pad and the caliper surface. In some cases this shim can fall out or simply rust away. This causes a change in the alignment between the pad and the rotor that is designed into the system to prevent squealing. This has haunted older Volvo owners for decades.

You can check for the brake dust problem by taking your car to a secluded area, going in reverse at 25 or 30 miles per hour, and then slamming on the brakes. This will knock out any packed in debris, and often stop superficial noise. But, otherwise, I stand by my first suggestion - just get your brakes checked out. They really are nothing you want to mess with. I've seen way too many people risk their lives and the lives of others to save a couple of dollars. It's not worth the risk. And if they feel as though they are not working properly, don't even drive it.

Answer 2

Usually when your brakes squeal it means that they are worn down. There is a sensor on the pads that scratches your rotor making that noise. Although that is the most common, there could very well be other problems. your best bet is to take your car in to get checked out. Pep boys does free brake inspections or you can take it to a place like Midas

Answer 3

Could be a couple of things but most likely you have disk brakes and it is time for service.

Special fabrication of the brake pads cause them to chirp when they reach a certain point of wear. At speed this sounds like a squealing...

Either that or check under the car to see if you are dragging a pig you might have run over.

Answer 4

Your car makes this sound for three reasons. If you have dick breaks, the pads or worn down to their indicators, some do this if pads or not riveted letting brake dust collect between the pad and rooter. or the pads are to hard. Same on old shoe style brakes. Except old shoe style brakes have no wear indicator.

Answer 5

You might want to have your car taken in and have your CV Joints (also known as half-shafts) inspected. If your car is front wheel drive, the CV is notorious for going out and making all sorts of noises. Regards, Z

Answer 6

You need to have your brakes checked.Squealing indicates it's time to get new brake pads

Answer 7

You need to replace your brake pad and possibly smoothen out the rotor drum or replace it.

Answer 8

You either need new brakes OR the rotors need turning.

Answer 9

get the brakes checked for needing replaced or they could just be glazed.

Answer 10

it sounds like you need brake shoes or pads.Bring it to midas and have them look at them.
