I was wondering how critical the soft material coating on the rotors is? One of my rotors dosent have as much as the other and I was getting curious if it will be ok w/o as much coating as the rest of the rotor? Is there something that can be put on it instead of the stock material?

 

you can high temp engine paint. I used red on mine but now I wish I used black. Paint the entire rotor with 2 coats on both sides then when you hit the brakes it will clean off the rotor face and leave everything else protected.

 

I dont know much about internals on a rotarty but doesnt that mean that the paint that is ripped of the rotor is going to be burnt through the engine? just doesnt seam like you would want to run high temp paint through the engine.

 

I was talking about the rotors inside the engine, not the brake rotors, hehe. Sorry about that. There is a thin layer of coating on the outer edges of the rotors inside the engine, this is what my question was about.

 

I dont know, but just spraying engine paint on the internals of my engine dont seem like the best idea to do. I also dont see how hitting the breaks with cause the paint on the engine rotors to be ripped off. If the paint is going to be "ripped off" I dont think hitting the brakes is going to make it come off any sooner. I have never heard of this so I dont know if it a real practice with benifits however, I know I would not spray engine paint on the internals of my engine.

 

It was a simple mistake guys. Bukwild thought he meant break rotors. Obviously you wouldnt paint the internals of an engine.

 

I was ind of wondering about this myself. From what I have heard it doesn't matter. But I don't know for sure.

 

The only thing I thought it was for was incase of a seal failure and a rotor crashing into the housing, it would save the housing from being destroid. This was my thought on their design.

anyone have any thoughts on this subject?

 

Yes I did. I just resurected this post. Any thoughts, I was cleaning my rotors the other day and of course after scrubbing all the soft coating off and admiring my pretty silver rotor did i remember the coating. Will it affect my rebuild ???

 

I have noticed no ill effects to removing it. Ive scraped it off on 10+ rebuilds.(its just easier to clean) Revisited the rotors on 3 of those rebuilds and not having that coating there showed no problems.

Dont give it any more thought.

 

I've often thought of putting a Teflon film on where the soft coating used to be. Never tried it though.

 

don't worry about it, the rotor sides almost never have that material left on them and i have never seen any adverse effects from it not being there.
