Went to adjust the parking brakes yesterday on my 4-piston rear Wilwoods, only to find that the drums are both pretty out-of-round. When the handle is adjusted to 7-9 clicks, the hub is alternately free and then at 180 degrees rotation was so tight it required a 3' piece of wood between the studs to turn it. Well, actually, one side required only a 1' lever but neither is correct. And yes, the rotors were torqued to spec and showed less than .002" lateral runout. Not really worth the hassle to send back, but still a $40 trip to the brake shop to make it right.
