How do you know the brake pads are low?...Did you take the calipers off and actually look at the pad...If you didn't actually take off the calipers you might've missed a revit from one of the brake pads making metal to metal contact...
you checked the rear too, right?...

No, I just know that when the pads are needing to be replaced they have that little metal "scraper" that makes a noise to let you know when to change them out.
I'll try and look at the pads themselves.
thanks again man ![[patriot]](graemlins/patriot.gif)

Well, is it a high pitch squeak or a grinding noise?...
Like I suggested, the best thing to do is visually inspect the pads...

Yeah...it might be a rivet from the brake pad coming in contact with the rotor. You should probably pull the calipers off and check the pads out. Reasons that a rivet might come in contact include: (1) the pads are just worn out or (2) the pad may be binding upon the caliper locating pin. When the pad "hangs up" on the caliper locating pin, the pads wear unevenly and you end of with alot of material on one end of the pad and little material on the other end of the pad. Sometimes one end of the pad may wear down to the rivet. In such a case, the rivet will come in contact with the rotor. BTW, do you notice any sizeable grooves in your rotor? If you let it go long enough, you may notice a groove the size of said rivet.
Anyway, I hope you have luck finding and fixing your problem.

Two things-
1: When you replace the brake pads, and don't turn the rotors, the 'lip' on the outer and inner edge of the rotor will rub against the edge of the brake pads sometimes and cause this kind of noise.
2: If the E-brake shoes on your rear discs weren't 'bedded in', you won't get a slow down at all. Is this where the scraping noise is coming from? the e-brakes may be dust- did you loan out your car recently? Friends, and especially girlfriends, just LOVE to forget to release the e-brake when they drive!

Yeah to really know whats going on here you'll have to tear it all apart. The brakes being only a year old normally I wouldn't think you would have gone through the pads already but that really comes down to your driving style. Some other things to check that haven't been mentioned above....on your calipers you have two 13mm bolts which hold the calper to the caliper bracket. These bolts screw into the two slider pins on the caliper. It is a common problem with these and the the cobra brakes for these sliders to seize or get stuck. When doing a brake job I always pull these out and paint them with anti seize. Another thing you can check is to make sure when you release the e brake cable that the caliper is actually fully releasing the rotor. Sometimes you may only get a partial release causing the pads to continue to drag while driving. Good luck

I'll try and check that out man, I appreciate your suggestions.
the thing that sucks most is that i'm not allowed to work on my car at all where I live. ![[Frown]](frown.gif)
If I set the parking brake and try and drive away, I'll move easily. I'm pretty sure one of my rear calipers is bad tho.
arggg!

Ya cars with little brake pad lining left typically have the same e brake issue that you are seeing. Little or no clamping force on the rotors. What happens is the piston becomes fully extended and has very limited travel left to provide any clamping force. You should be able to look through your wheels at the brakes to see whats left of the pad at least the outboard pad unless your brand of wheels don't expose the caliper at all.

I have a similar noise coming from my car, of course I don't notice it often unless I have both windows down and the engine is out of gear and I'm rolling (exhaust too loud )
I thought it was my wheel bearings, but I replaced those (they were in very poor shape anyways) and now the noise is still there and goes away when the brake pedel is pressed lightly. I think its the front pads or the rear shoes out of adjustment? I'm not sure I got the adjustment of my rear drums perfect so that will be the first thing I look at next.

ah hell, I'll just bite the bullet, so to speak, and replace all 4, just to be safe.
Come to think of it... When I 1st bought the car, it make this clack-clack- sound when I drove it, and the guy told me that it was just the center caps on the wheels ![[Confused]](confused.gif) A buddy of mine and myself pulled all the wheels off and discovered that the shop that replaced the front pads had not installed the little metal clip that holds the pads apart on the front rotors ![[Eek!]](eek.gif)
Thanks man Ill let you know what I find
