I was looking through my Haynes manual last night and saw a picture of someone cleaning up a rotor. The caption said something like "be careful to not damage the soft material along the edges of the rotors". In the area between the side seals and the outer edge of the rotor there was something that looked like built-up junk, so I took a scotchbrite chucked into my drill and removed it. Did I ruin my rotors? I'll try to get some pictures tonight.

Thanks,
Rich

brake rotors? engine rotor?

Hmmm...I guess I've never seen side seals on a brake rotor LOL. Sorry, engine rotors...

oh boy, not a good idea to get wacky riled up.

possibly, depends if / how much material you took off the engine rotor.

many people clean with degreaser and a nylon brush, but that's a much lower speed contact.

uh oh. He didnt take very much material off at all. Basically, it just took the funky looking stuff off (bumpy and dirty looking) and it mainly just smoothed the edge out.

Side seals, My first thought was WTF are side seals (thinking about brake rotors) then, ohhhhh side seals. I believe they're called corner seals

no, there are actually side seals too

Side Seals, Corner Seals, and Oil Control O-Rings are the 3 types of things you find on the side of the rotor

OK...here's the picture...hopefully all the confusion will be gone.

did you only do it in that one section, or all of the rotor?

I cleaned it all off, from all 3 edges of both sides of both rotors...seemed like the thing to do at the time.

ouch, you can probably still build it, but it will not have that safe guard when the side seal compreses all the way it will be metal to metal. The engin would most likely have a desent life span. ( I have never built a engin with rotors like that, this is just what I would think)

P.S. Port it BIG so you have a motor last 15,000 miles anway...

That coating is to reduce carbon buildup over the life of the engine. The rotors arent ruined.
