needed new pads for my hydro brakes setup and ran across a thick pad kit from promodraceparts.com. They used a alum spacer and longer bolts to accomidate the thicker pads. Got my kit in and the longer bolts were missing from the kit no problem though. I was taking a look at the stock cable caliper and noticed the removable back plate was a little thicker where it bolts up. Took that one off and used the bolts out of the stock one and it works perfect. Diddnt have to shim the caliper or anything.
