Ive got a set of wilwood disc brakes, Dynalite Pro Series Front Hub Kits part number 140-2285, on my 68 camaro. All was going good till about a month ago when it started eating up wheel bearing, ive replaced them 3 times and done everything exactly by the book, does anyone have any idea whats going on? Another queation is im running a 1" bore wilwood tandom master cylinder and it doesnt seem to be stopping like i think it should it wont even lock up the front brakes and there only 6 inch wide front tires, the peddle is as hard as i rock so i know there isnt air in the lines, i just feel that it should stop alot better than it does. Any suggestions on these 2 issues would be greatly appreciated because its driving me nuts.
