Hi,

Has anyone had the issue where the park brake valve allows oil to flow from one master brake cylinder to the other. CSH is S/N 14004 so I have the original type master cylinders on the pedals.

If you depress the left brake before the right hand pedal, the oil is able to travel into the right reserve cylinder. But if you depress the right first, the oil is contained within the system. We traced the issue to the park brake valve, this is the only spot where oil "can" travel from one cylinder to the other.

Better still where can I get a new valve, over here in Oz, 114 spares are hard to come across.
