I'm confused. What sort of dirt is there in the wheels? Isn't that usually brake dust? And how would the MC dirty up the rear wheels? I would think that if you had brake fluid leaking on to the wheels, the paint would be stripping... do you have dust shields properly mounted?

Do the rears squeak when reversing and on the brakes and sometimes when braking when going forward, too? Or do they squeak whenever the car moves backward regardless of where the brake pedal is? If they squeak primarily right after startup, that could just be accumulated condensation/surface rust/dirt. Our Corolla occasionally squeaks the brakes when I start driving -- nothing but accumulation of dirt and rust from sitting.

EDIT -- haha -- disregard the first paragraph -- rcurtis set me straight
