After 8k miles I needed new pads for my front and rear Zeus disc brake conversion. I wanted a bit more bite and to stop fade when towing big trailers etc.
I have just fitted EBC green stuff Pt No. EBC DP2108. wow massive difference well worth the upgrade.
However there seems to be problem with supply. EBC no longer make them however they are readily available through classic/vintage car stockists.

This company managed to track them down through their suppliers.
