My 2004 hatch has an odd noise from the rear, pretty much when cold, and is now much worse because... it's cold out!
The rear rotors were warped, I thought that might be it, so I replaced just the rotors, but the noise continues. it's like "tocka-tocka-tocka-tocka...", but will quiet right down if you press the brake pedal. As soon as you lift, the noise may reappear. It tends to go away after several miles. It can get somewhat louder if you turn left or right.
The new rotors are Wagner (as were the old) that I got off Amazon, so I don't think that's it, besides, the NEW rotors aren't warped! Is it possible that the wire clips on the calipers do not have enough tension? I didn't remove them when I took off the calipers, so I may have bent them too far when removing/replacing the calipers (just a guess on my part...) I don't have any other explanation. But, they don't really LOOK wrong (not obviously bent and not contacting the caliper mount, that would be an obvious thing).
The rear bearings were replaced two years ago at Mazda Bedford (they replaced the bearing AND the hub it was in, saying they don't just press out the bearings any more). So, I don't think it's bearings, and the noise wouldn't stop when the brakes are applied. Any other ideas?
