During a rebuild, what do you guys use to clean the carbon from the rotors and housings?

 

I soak it in degreaser, like simple green. Then use a high powered gas steam cleaner and blast the crap off. Takes awhile to get it all clean. But eventually it ends up all *bling*

 

I soak them in kerosene, and then take a wire brush to the rotors. For the rotor housings, and end housings, I spray with degreaser and take the pressure washer to them.

 

ATF maybe? Hey just a suggestion.

 

Racing beat recomends that you soak them in solevent and use a brush or wooden dowel to get off the carbon. They say specificly not to use wire brush or metal as it will destroy the apex seat.
I can quote it if you like. I have the book next to me

 

I meant on the faces of the rotor. I use something less abusive on the apex seal area.

 

When using a wire brush, always make sure the type of wire is softer than the netal you are cleaning. Otherwise you will scratch what you are trying to clean. A brass wire brush should be softer than the aluminum and iron.

Lots and lots of solvent also helps. That and some good ole elbow grease.

 

The easiest is to soak in Kerosene or ATF fluid. The carbon will soften up a bit and use a scraper on the rotors. On the apex seal groove I use a feeler gauge and gently scrape off any carbon in the area. Most of the time. just a swipe with a cloth dipped in kersone does the job. Don't use a wire brush . A paint scraper does it sooo much easier.
