Hello.

I just did the scarebird disc brake conversion. It went on without much trouble. Had to do some extra grinding, but no real complaints about assembly. The brake pedal feels great, and it stops much better.

However, I noticed a slight rubbing sound when I hit the brakes. It's not a grinding sound, like what you would get with old pads and it's not a vibration like warped rotors. After about 30-40 stops, I let the car cool down and then took it for a drive. Didn't hear the rubbing at all, until after about 2 miles of driving it came back.

I pulled the wheels after the drive and took a look, and nothing seems out of the ordinary. The calipers are definitely not rubbing on the wheel, as I thought they might have. No abnormal wear on the rotors.

Anybody have an idea what this could be?
 
MIGHT be completely normal. Only when applying the brakes?


Might try and find a great big parking lot and a friend to ride a bike, etc, alongside, or maybe "rig" a camera/ audio recorder
 
Yep, only when applying the brake. Seems I could drive along forever and not hear a thing unless I press the brake. And after the last drive, it seems to show up after the brakes have had a chance to warm up.
 
metallic pads? Did you know there is a proper way to "bed in" the pads. It involves multiple hard stops from a certain MPH but I am not sure on the specifics. Just a thought....IDK...
