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.

I have no idea what is going on with your bearings. Your master is wrong, a 7/8" bore would add a lot of pressure at the equal pressure input from you. Could be as much as 20% more pressure. As for stopping / locking the brakes. Those 140 - 2285 are pretty small at 10.75 . They will stop the car, but they are not exactly big brakes.

Well thanks for the info on the master cylinder im going to go ahead and swap to the 7/8 and see how much that helps.

I was wondering if you had drums on before the swap and if so did you notice how much this kit offset the front wheels. just curious because i was looking into the same kit. Also are you happy with it so far besides the bearing problem?

thanks

CRJ, it is about 3/16 wider, nothing noticable. Unless your running 15" tires, I would highly suggest the 12.2" version of the kit, 140-7675. This is one case bigger is better, but they need 16" or bigger wheels. Regardless of what size you need, check us out when your ready to buy.

my guess would be that you are running too much preload on the bearings, and once the hub gets warm (which it will do either from to much preload, or too small a brake that soaks heat faster than an undersized disc can disappate it) the preload gets even higher, and presto.. you are toasting bearings faster than anyone cares to replace them..

try and run alittle more preload... just finger tight.. and if you drive "spirited" considder a bigger brake kit
