I spoke to my local Tps yesterday and they said it is no longer available but I had a look thru the pile of parts that came with my car and I found 2!the only problem I have is that the block that I have has 3 outlets not four is this correct?
I think there are 2 different values of valves. 15 and 35. These refer to the cut off pressure the valve is set at, lower pressure one for discs, higher one for drums. The valves are identical internally except for the preload spring. For Disc brake valves use part number 533 612 151 A and for Drum brake valves use part number 533 612 151, neither types of valves have the part numbers on them, only the pressure rating.
