Metal Pads on Discs marked "Resin Pads Only"

I've recently swapped my Resin pads (M07) for some Sintered ones (M06) because of this crappy weather we've been having. In the mud and water, the Resin ones actually started to disolve! :?

Anyway, braking performance is much better and no troubles on Twrch Trail at Cwmcarn on Sunday, which certainly put them through their paces!

However, today I noticed that the discs are marked up with "Resin Pads Only". Why is this???? Is it that the metal is softer and the sintered ones will eat them away?

    brakes are? i guess shimano but which and year?

    tbh i cant see it mattering much it could just be something to do with the hole patterns.

    They are Deore M535 from 2006.

    I had discs that said resin pads only all that happened when i ran sintered pads was that the discs went a light blue colour when riding downhill, they seemed to stop okay, :shock:

    Craig. i would drop ulitimate pursuits a line.

    as i have a feeling that it could be something to do with the heat generated by the sinteredpads and the "floating" disc design.

    According to Tim at Shimano Australia, some Shimano disc rotors do use a steel composition that is adversely affected by sintered pads.

    "It can chew 'em up," is what he tells me.

    Probably best, therefore, to stick with the resin pads, or upgrade your rotors.

    Rotors designed for use with mechanical disc brakes are susceptible to warping at high temps( ruomour has it), as they're not heat treated to such a high degree as hydro versions. (hence the blue tinge) basic hydro brakes are also sold with these rotors in some cases, but you can get new rotors for as little as £20 which will sort it if your rotors get mangled.
    It's nice to be important, but it's more important to be nice.

    I believe the heat generated when using Sintered pads can also be detrimental to the brake piston seals on some manufacturers brakes.

    I know Magura only recommend using their own proprietary pads in their brakes and that you break the guarantee if you use other brake pads than theirs.

    Are other manufacturers the same? Hope, Avid, Shimano, Formula et al?
