Does anyone have a non-damaging favorite brand they use? I'm also wondering if it's possible that certain types of cleaners can cause PCCB's, or any brakes for that matter to be more prone to squealing.

Any thoughts, or do I have a great imagination?

 

I find that good ole soap and water works great, with maybe a dash of simple green in the bucket if they are more dirty. To be honest, I took the wheels off and cleaned everything thoroughly when I bought the car, and the wheels and brakes haven't needed much more than a rinse since then. The PCCBs are worthwhile for the easy cleaning, if not for the performance.
