Sintered clutch plate

If a sintered clutch plate was to be available for the LT as it is for the boxer twins range , would this material absorb oil and brake fluid .
I ask this question because these clutch plates don, t wear out and they are supposed to be a lot stronger than the original plate .
Just imagine no more clutch problems with leaking fluids.

Sintered metal friction materials, brake shoes, clutch pucks, etc. are "porous", and would still tend to "soak up" and then release any fluids that get on them, so would still cause a clutch slippage problem if brake fluid/oil get on them.

I don't know much about ceramic pads, but I think they may be organic base with ceramic particles in it, similar to how semi metallic brake pads are made. If they are fully sintered ceramic, they MAY be homogenous enough to avoid fluid penetration. However, there are ceramics that are also porous in nature, depending on what is desired of the product.

Hopefully someone with technical knowledge of ceramic brake pads will comment.

Just found this on a web site:
--------------
Since they were first used on a few original equipment applications in 1985, friction materials that contain ceramic formulations have become recognized for their desirable blend of traits. These pads use ceramic compounds and copper fibers in place of the semi-metallic pad's steel fibers. This allows the ceramic pads to handle high brake temperatures with less heat fade, provide faster recovery after the stop, and generate less dust and wear on both the pads and rotors. And from a comfort standpoint, ceramic compounds provide much quieter braking because the ceramic compound helps dampen noise by generating a frequency beyond the human hearing range.

------------
Based on that, I would think that ceramic friction pads will suffer the same problems as anything else if brake fluid gets on them.

I also know that people who have tried ceramic brake pads on the rear of the LT eventually had the same squealing problems as before, so that is not a "fix" for the noise either.
