Brake Squeak and sounds
 

Hey guys, So a few days ago I installed new Rotors and Pads for my brakes. I went with the DBA Slotted T2 Rotors, and the Stoptech Brake Pads.

After a few days minutes of use the brakes were squeaking which I figured was normal, but it has still continued. Followed the guides to a T to make sure that the install went smoothly and I wouldn't mess anything up.

Now fast forward to yesterday and now when I'm going at slow speeds I hear what seems to be the pad hitting the rotor every few milliseconds making a "woosh" sound whenever it does. So it just 'woosh's' every 10 milliseconds or so depending on how fast I'm going. I want to think the brake pads aren't secured in their positions enough so they're moving around but I don't think that even seems possible. Just to note, the sound does not happen when the brake is not at all applied.

Does anyone have any help as to why the brakes would squeak and why I would be hearing these sounds?

I've never done aftermarket rotors or pads before so this is all new to me. Thanks for the help in advance. If needed I can try to get a sound clip of the "woosh" noise if someone requests, but I'm not sure it's loud enough for a camera to pick up and since I only replaced the front pads I'm not sure how I can get the front wheels to move fast enough.

I assume some of the noise is having slotted rotors. The j-hooks on mine make this funky popping noise, and it freaked me out the first time I heard it.

As for pads and screeching... Better pads need bedding to keep them quiet, and in my experience it may or may not keep them quiet forever. Mine can get pretty noisy around town and in stop and go traffic... Re-bedding helps a bunch for a while.

What is rebedding?

Ahh, sounds like it's time to learn about bedding your brakes! Lots of info out there, both on this forum and elsewhere.

One of the most useful sites for brake info is from Stoptech. Here's what they have to say about bedding in new brakes:

Ordinary street brakes tend to bed themselves in if you drive reasonably hard.

Higher performance brake pads need more heat than you normally get when street driving in order to bed in quickly and correctly. Fortunately, unless you've glazed your pads by driving way too hard or way too gently you can rebed your brakes easily by driving with enthusiasm.
