I've been restoring a 574. It's up and running fine. When I was
working on bleeding the brakes, it took me a while to discover why
fluid wasn't getting from the oil cooler to the master cylinders.
There is an orifice that is located in the hose feed line. When the
orifice is not in the line, there is a good flow (with in the specs
quoted in the maintenance manual). When the orifice is in, the flow
is not sufficient to run the brakes. So, my question to the experts
is, do I need this orifice? I intend to get a new one, on the
assumption that it's clogged, but I'm wondering if I really need it.
