So today I got around to replacing the seals on my Brembos. My right front is almost black no longer brown and upon pad inspection after last track event I noticed un-even wear on the pads. My only thought was a dragging piston. Upon inspection 2 of my pistons (outside passenger) have the teflon esc coating wearing off and very rough. This could be the issue I think. Anyone else seen to this problem?
I have never had any bias issues on track but the right caliper is def. getting worked more.

Can I get aftermarket pistons? (ie stainless etc)

Send them in to a company like Swain and have them coated?

 

Damn, mine are still somewhat red. I take it you track the car a lot?

 

Yeah it is a track car.

 

I would say you got your moneys worth and IMO look at replacing them with an aftermarket set up. I would be more concerned about what you can't see.

Are you running any brake cooling?

 

Might be worth looking into on the stainless pistons. I haven't found any for the evo, but here are some for the Corvette.

Maybe they would have some interest in making them for the EVO too, I bet a lot of guys on here would be interested.
