Hey all, I changed my rotors and pads with all new ones about a month ago ( prob 1,000 miles ago), and ever since I hear this weird squealing noise. What is odd, is it only happens from a stopped position. Bear with me while I explain it. If I am at a complete stop on level ground and let off the brake (it is an automatic 2010 Mazda 3 2.5 Sport), and i start to roll forward at 2-5 mph, is when it makes it squeal and it goes with the turn of the wheel. Once I press on the peddle or the brake it goes away. It never happens above 10mph. It is just an annoying sound and I hate it.

At first I was thinking a warped rotor, but I dunno about that. I also read that it could possibly be just the pads are loose and it makes that sound. I read to try and put something like copper grease on the back of the pads and then see if that will fix the problem. What do you guys think? Thanks!

 

What's with all of the embedded links in your post?

 

Did that fix it? I'm not sure why it was like that.

 

Yup, that fixed it. Never heard of the kind of brake issue you're having unless the lug nuts of your wheels aren't properly torqued down. You might want to take the car to a shop and have them give it a look-see.

 

Did you follow the specific brake pad bedding instructions exactly? Also, Mazda 3's of these years are notorious for noisy brakes. I find that rebuilding the seals in the caliper will resolve most of the noise issues. Rebuild kits are very cheap online. I do not recommend buying rebuilt calipers, I would rebuild them myself.

 

did you buy cheap breaks? if you buy a "no name" break pads and rotors, also known as economy you will almost 99% will get squeaks and squeels from them..

did you grease the sliders??? did your retaining clips move freely??

keep in mind

A correctly serviced caliper should slide smoothly on its guide pins or guide surfaces, and should allow the rotor to turn freely when brake pedal pressure is released. If the caliper won’t release, the interior rubber of the brake hose might be peeling and blocking the return of fluid to the master cylinder reservoir. In other cases, the master cylinder push rod or brake pedal height might be incorrectly adjusted, which prevents the master cylinder from releasing the fluid pressure from within the caliper.
