cleaning internals...?
 

well i did some searching, and i plan on using simple green, mmo, and a brass wire brush to get all the internals clean. i just wanted to make sure the simple green and mmo are ok on the bearings? also is it ok to use the brass brush on the rotor housings? thanks in advance.

Don't use a brass brush on the chromed rotor housing surface (or side housings). The other areas on those parts are fine for cleaning with a brass brush. Use a 3M pad on the chromed surface for the rotor housings, and some 800-1000 grit wet sand paper on the side housings.

As for cleaning, parts cleaner solvant will work the best as it can be a time comsuming process if you have carbon build up on the rotors.

I wouldn't use any "metal" brush on any surfaces (bearings/housings/plates)...I think bruce gives good examples of what to use in his video...I can't recall at the moment, and its been over two years.

Why not? More elaboration is nice for threads like this.

Same to you sire why not? I can see not to use such on bearings but the end plates and housings? I've used a wire wheel to clean my rotors and housing faces with no ill effects.

While brass is a softer metal type brush, it can scratch the chrome. Most builders that I spoke with recommended 3M pads for the rotor housings and some sandpaper for the side housing wear surfaces.

I've always cleaned rotor housing surfaces with a brass brush - no problems at all. I typically use Castrol Super Clean and a brass brush for most everything. Get a few brass brushes - they do wear down :).

A scotchbrite pad would probably be a little quicker/easier for cleaning the rotor housing surface, though.

The only thing you really have to be worried about is the bearing surfaces in the stationary gears and rotor bearings. I typically just leave them be - they don't need cleaning, and they typically get exposed to enough degreaser while cleaning the rest of the part that they're fine.
