I have a subaru outback 2002 limited sedan, the breaks will go bad in as little as 2~3 months, in which time it is babied and not driven very far every day, if at all... why are my breaks going bad so often and why is my wheel shaking before the breaks are replaced for 1600$ a whack, calipers rotors and pads brand new 5 or 6 times in 2 years!!! any advice?
