A quick search on ebay will usually find you one for less than $50, I've found it difficult to lookup at local part stores sometimes. Obviously if you are going back with stock stuff, you will need Disc/Drum for a K30.
I did search propositioning valve, but when the part shows up, it doesn't say anything about combination valve or residual valve? Thank you again for your input sir
