For a while TRF was handling REPCO pads (also from Australia). These are
also semi-metallic and there's less brake dust, squealing, etc. I used these
on my 4 and on my 6... also my Volvo 240 (all around), my Buick (again, all
around) , and I just noticed the Mercedes will be needing front pads...
Repco again. They are getting harder to find... no luck yet on the MB.
