Just picked up some new front rotors to go with the brembos.

Decided on the new EBC Ultimax stuff as they're good value for money and seem to be going down well on SCN

Anyway, the pic on the website shows the bells are anodised, but the friction section of the disc isn't.

But on receiving them, even the friction section is anodised, and seems pretty well on and doesn't "peel" off easily.

Do I just mount these as is, and the let the pads burn / wear off the anodised layer?

:confused:

I was told that the EBC pads have a break in coating on them and when using them you just install them and all will be fine.

I'd guess the same will go with standard pads too, although I'm not sure how fantastic that black coating will be on the pad surface.

One selling point was that the stuff only wears off on the friction surface where it is rubbed by the pad so you don't get rust elsewhere.

FWIW it isn't anodised as the discs are not aluminium and I think it is some form of paint.

LOL Marketing strikes again then - or at least they don't know what they're talking about (nothing new then!)

just get on with it mate, it'll all be good.

List of qualities that aluminium has that I'd want in a brake disc - none.

Its not an anodised coating on the discs IIRC, like mentioned before, its just a coating to prevent corrosion. (ever seen the lovely rusting on the centres of some discs, looks horrible). Similar to the Black Diamond brand of discs--start off Black, but once pads start to grip the discs, the black wears to reveal shiny metal. Its all good, so dont worry

I don't know they are easy to recycle and don't rust.... that's it mind.

And lightweight!

Yes. Light -> Low total heat capacity. And a fairly low specific heat capacity too in the case of aluminium IIRC.

No rust -> Ok, I'll give you that, since they're not made of iron! Aluminium does corrode, mostly producing a soft whire powder when it does. What inhibits ally corrosion is a layering effect with the corrosion on something like a clean casting or plate.

Aluminium is also soft (so will wear quickly in a brake application) and weak so we'll lose the weight benefit recovering adequate strength.
