    blue led headlights, 285/75/16 grabber AT2's, custom pedals, custom shifter, flowmaster 40 series muffler, bedlinered fender flares, 2.5" lift kit via shackles and spacers, custom exhaust out the back, chrome exhaust tip, and Herculined bed, Weathertech floormats, Cabelas Trail Gear Camo Seat Covers ... Nice thing was I got the truck for $4000
    Since I put my larger tires on my truck (from 265/75/16 to 285/75/16) and my spacers when I step on the brake fast, or hard I get a tiny bit of throb, like the brakes are pulsing. I don't think its rotor warp, but I guess it could be, are my new tires just really heavy for the brake system. I haven't got a brake proportioning valve kit yet, is this what it is? thanks ahead of time:D

    getting there....
    just saw this.

    well....the added weight could be causing alotta drag on the rotors....which in turn, the heating and cooling of the rotors could cause them to warp. may be time to go with a beefier set of rotors.....or a set thats slotted that can cool down better.

    Is it nose-diving a lot when braking?
