Ok , the mechanic looked at it, nothing seems outta place.
Talked to Dave Z. as well... he said there is nothing to worry about ...give it a few more days and it should go away...
I feel kinda bad now for accusing the shop manager for improper install..he spent a few hrs to take each wheel off, check each caliper, piston, bolt etc...will have to see if the color improves in the next few days...
Maybe after all it's my fault for being so hard on them with the bed in process...it sure was fun.
