A while ago, I bought 8 rubber cups for the rear wheel cylinders on the "S" - 5/8inch bore.
Recently went to fit them but the new cups were a different PBR part number than the old ones that came out.
The new ones have a chamfer around the main sealing lip while the old ones have a sharp edge.
Old cup is P5057 (lower one).

Have tried to find a PBR applications catalogue on the net to see what I should have or what the new ones are intended for; but no luck.
Does anyone know what PBR part number/s suit "S"?
