How do you keep you wheels clean?

[sasha055]

Hi,

I have another question.

I have a "whoooo whooo" noise coming from my left rear wheel, I thought it's a wheel bearing going bad and bought all the tools and set the time aside to replace it (in 2 weeks)

However, Yesterday after reading more threads on brake dust, I sprayed everything inside the wheel (including calipher) with brake cleaning sollution, waited 2 min and hosed it down.
Suprisingly my bad wheel bearing got better.. noise almost dissapeared, I can hear it only when going 70+mph...

I suppose it's some kind of brake dust build up going on inside the rear wheels..

What should I do next? (before ripping off my bearing?)
Change brake pads? bleed the brakes? anything else?

Thanks
Sasha
