Hey Gary, I'm all ears too, but it's hereditary for me, as was my father & his father, too! On a serious note though, how big of tire do you have now? Discos are heavy trucks w/small brakes & tire size does make a difference. What kind of new brakes & rotors do you have? How about brake fluid, do you change it? I'm really a firm believer in changing the brake fluid every year, but I just enjoy changing fluids I guess. It seems to make Rover happy to get the attention, and I sleep better knowing my fluids are clean! Good Luck! LRW.
