That is your brake pad wear indicator. It is rubbing on your rotor. either your brakes need to be changed (but you said they didn't) or the indicator is bent which is causing it to prematurely rub on the rotor. Your brakes will work fine when this starts, cause it is just a warning. When the noise stops (atleast from what I learned the hard way) your brake pads are over worn and will grind into your disks. Did you check your inner rear pads when checking the pads wear life? Those are the two that ended up digging into my rear discs (both sides) cause I ignored the warning until it was too late and the grinding noise of the pads digging into your disks is the worste noise you will hear in your entire life!! It can make a grown man cry!

 

Nobody cares about your DIY Zumn!!!!! jk

 

^ Ill find you!

 

Good luck getting that on a plane to get here!!


And I would say your 8 could make it here quick, but, you parted it out.....

 

MMW, there's already an excellent rear brake DIY (thanks to Zumn). No need to reinvent the wheel (pun intended). And the caliper toolset pictured above is well worth the relatively small investment (Harbor Freight as well).

edit: I didn't have to relieve the caliper bleeders, but did of course loosen the master cylinder reservoir cover. Every time you open the bleeders there's the possibility of introducing air into the lines, which must then be bled - unless of course you have Russell speedbleeders as I now do.

 

The pads are not worn down though, thats the thing. I've changed brake pads before and these do not need to be changed. There is still at good quarter of an inch (if not more) of pad left on them. And the noise I am hearing is not a constant squeal either. It is a creak or scraping noise when the wheels go around. The faster the wheels are going, the faster the noise (if that makes any sense).

So the wheel goes around...I hear the creak noise for a half a second, then it doesnt do it again until the wheel goes around again. Sorry if that is confusing. Trying to explain what I am hearing.

The little metal plates on the back of the pads do seem a bit loose and/or rusted. Would this have anything to do with it?

 

Dumb question, but did you torque down all the lug nuts? I didnt do this once, and it did that when I was moving the car.

FWIW, I just changed my rear pads, they had very rusty & dirty shims/plates like you are mentioning. I dusted them off a bit before using them, but havnt had any noise issues since i put on the pads

 

I can just borrow JEDI;s

 

 

Yeah, I torqued all the lugs with a torque wrench to 106 ft lbs or so.

 

Hellz, all ya'll gots to do's is pute a lil **** inta it an ya'll be aight. BillyBob would neva steir ya'll wronge!
