The short of it is, I removed the master cylinder and didn't install the new one until months later. Tested the brakes in and out of the driveway but later noticed two springs on my work bench. Assume they are part of the vacuum servo, but can't remember. Does anyone know where these might go? Big one is 30mm x 52mm; little one is 15mm x 28mm and slightly tapered. Can't find an exploded view of system that shows them.
