Squealing Brakes Whats That Noise in Your Car Truck or SUV

Oh, that doesn't sound good.

Before I actually pull the wheel off, just look at the rotor, see if you can see anything. I can see a little stripe right there, that's an indication of what might be going on. All right, so let's look at the brakes. If you look right next to the caliper bracket right in there, you can see that there's an actual squealer that is actually touching the rotor which that's an indicator to let you know that your brake pads are getting too thin. This is the brake pad wear indicator, that's what's making our noise. Sometimes they call them squealers. The reason why they call them squealers is because that's exactly the type of noise you hear when this is actually contacting the rotor while you're driving down the road. Now they put these on here so that when the rotor actually contacts there, there's still 2/32 left of pad material which that's giving you the warning that you need brakes. In addition to these squealing, something that could also cause it is the anti-rattle clips if these were bent and contacting the rotor. Also, the backing shield. If you got a rock stuck in there or the backing plate or the plate was bent up, sometimes they rust a little bit and that could cause a squeal as well. But it's a pretty distinct sound when this is actually squealing. Sometimes these backing plates will bend, it'll be contacting the rotor, that can cause a squeak. Or you get the rock right in between there and it'll cause a squeal as well.
