Thanks rrdstarr, this time i tried Burien Nissan since they got 'The Excellence Award' from Nissan ... well i guess they just had to screw up my X ...
... after the brake job was done (3 hr job), i drove her back and after 10 mins of driving, started hearing a clanking sound from the front, it took me some time to realize that it was coming from the front left wheel, then it started happening everytime i hit the brakes, ... i took her back, ... they either had forgotten to put on of the big screws on the break pads or it had fallen off because it wasn't tightened well. In the end it took me another 30 min drive and a day or work, ... not sure if i'll go back there again. The staff was courtious enough though.
I think i'll go with rrdstarr's advice and try Auburn Nissan next time.
