I know the ball joints are the same I am having trouble converting from 4 piston bendix disc brakes to 1970 52 series disc brakes what all do I have to change out? ray: I really wana get my 69 wildcat back on the road. I've looked every where I even sent my calipers to cardone and they couldn't even rebuild the 4 piston calipers nor do they even make brake pads =( if anyone could help me it would mean the world to me!
You have to send the calipers to Apple Hydraulics in Calverton NY. They are the only ones that can stainless steel sleeve and rebuild your calipers. last time I checked, they got $265 a caliper, but prices may have gone up since. The pads which remind me of Mickey Mouse ears are part number "D16". There are a few sets on Ebay right now. As far as rotors, they are hens teeth. Ive seen them sell for $400 each
