Hiya Andy, yes it is mate, so whats wrong with your calipers as in why can't they be repaired, any pics??? Shame if its true as CP3796 are great calipers. I take it you've got 355x28mm discs?
Marco, I really hope your right but are you sure, AP state 2 sizes:
355-362mm or 330-355. I've never had a CP5555 caliper in my hands so i'll take your word for it, i'll ask AP for a layout drawing as I hope to use a pair with 378's both front and rear
