Recently the truck has begun to shudder under braking, under heavy braking it stops but light to medium braking the whole truck shudders.

Had pads replaced about 15K ago things were fine, truck has always had a slight vibration at highway speeds no matter how well balanced

Maybe warped rotors up front, what's a good replacement, Stock, aftermarket stock replacement from local stores, upgrades?

 

See if there's enough meat left for resurfacing..............
