RE: xxl brake upgrade
Did you use all three original pads with the single 8ight disc? I put1 on1 side and two on the other, it holds the disc straight and has no drag worth mentioning.
Re-reading your first post.... "because the pads were wore down to bare metal on my stock shoes".... you do know the stock pads are just metal pieces right?
Either way you've done yourself a favor, your driveline will thank you.
