"Metallic linings are double sintered as compared to the single and much larger sintered ceramatalix linings."

I recall that the cerametallics (I assume a cermet material) were used on the Corvette SS and maybe the early C1 and C2 HD brakes, but if anyone can explain the above statement I'd love to know.

RPO 684 was the metallic brake option for C1 Corvettes. These shoes were about 2" wide, both front and rear.

Drum were the same castings as base brake drums, but had a finer surface finish and different finished part number. T

The following metallic brake shoe unit part numbers (2 three-puck primary and 5 five puck-secondary) are from my 2/77 P&A catalog Group 5.017A:

Duke, I believe you are thinking of RPO 686 which used 2" front shoes and standard drums with a finer surface finish.

RPOs 684 and 687 used 2-1/2" front shoes and the wider, heavy, finned brake drums.
