I purchased the kit from Perf. online, the lug bolts on mine are longer because the rotors mount behind the stock hub. It is necessary to remove the stock lug bolts from the hub prior to adding the rotors. It was necessary to grind the kingpin retaining pin nut a small amount to keep it from interfering with the rotor mounting bracket, but it was a small amount.
I have a question though, Since I am retaining the stock master cylinder position ( replacing it though) and have not lowered the front of my truck, will I need to install a residual valve? my rotor inlet is on the top of the hydraulic area on the rotors and since I am working with the front end elevated till I get the installation finished I don't have any way of determining if the rotor inlet is actually higher than the master cylinder. Anyone have experience with this??
Thanks, jim
