Why are my car breaks squeaking and squealing?

Question

It's only happening when I break if I'm driving slowly (like in stop and go traffic, or in a drive through, or parking lot). It happens mostly when it's damp outside. The breaks were replaced a number of months ago, so I don't need new ones...why is this happening? It's quite loud and getting embarrassing!

Answer 1

I am an ASE certified brake tech, so I'l give you the possibilities.
Noise is the result of vibration. many shops do not lubricate the backs of brake pads or any backing placte contact points, thus allowing the vibration to "sing" through the metal components, usually the brake anchors.
Another point is the wear indicators may have been improperly installed, causing them to drag the rotor.
Dust from the brake pad can cause squealing as well, so can dirt.
If moisture is present, a light film of rust on the rotor's friction surface can cause squealing, too, but this is usually gone very quickly.

I also want to point out that the first person to answer your question is very questionable, as your car does not have, and no car has ever had, routers as a component.
A router is a tool for shaping wood, usually cabinets and crafts, not an automotive part.

Answer 2

Assuming you have disk brakes, which virtually all newer cars have, the problem is one of 2 things. 1. The brakes, which you say are new, were installed incorrectly causing the pad to vibrate when you press down on the brake pedal. or 2. there's dirt caught between the disk and the rotor.
In either case have it taken care of right away or you'll destroy your rotor.

Answer 3

Probably just dust or dirt on the brake pads. Most places have free brake checks though, just be careful they dont come up with outrageous things to fix it and try and jip you.

More than likely if you've had the brakes replaced recently, its just dust.

Answer 4

Since you said that you just changed your brakes. Then there is dust stuck in the middle. What you could do is buy brake stop squeak and apply it between the brake calipers

Answer 5

if the work was done correctly using quality parts you may be getting noise from the " metallic " compound in your pads/shoes, we're trying to get asbestos ( quiet but carcinogenic ) out of the friction material and the "dust" from the new material can be noisy.

Answer 6

if there new it cuz there to tight but if not its beacasue the metal is scrathing your router and you need new ones.. change them befroe they miss up you router
