Hey Wan520i !
When wanna go bentung and eat lah !~!?@?@?
in this situation, u will probably see the center of the brake pad are lesser due to the burning process..
You are recommended to use NEW BRAKE PAD.
if u use the old brake pad on the skimmed disc,
it will probably less brake respond & vibration stay there.
since brake disc & brake pad having un even wear (moreover the scorch mark on the center line)
if u sand down the brake pad it become thinner & can u sure that your brake pad flatness are 90 degree flat from the brake disc ? unless u send it machinary shop to shave it. worth it ???
if u use back the old brake pad, u will end up feel the vibration due to the uneven wear on the brake pad cause back to your newly skimmed brake disc.
in another words the brake disc will having the same mark as how uneven on your brake pas.
Just my 2cents..
