The saga continues.
Z-car veteran DKW and I worked on the rear brakes for a couple of hours yesterday. Work included dismantling and re-assembling the back-brake proportioning valve. Same thing. Brake fluid to the valve, but only the occasional drip gets through to the T and the wheel cylinders.
Someone advised me of a used valve for sale on E-bay. Price was right, but somehow the seller couldn't figure out how to get it from the U.S. into Canada.
Questions: Is this much trouble endemic to the early Zs, or is mine a rare case? If it is rare, I'm open to hear from anyone who might have one to sell. If it is common, I'd like to know of peoples' experience with the Willwood adjustable prop valve. I notice that it is recommended for use with disc brake conversion, which is not the case here. My only previous experience with Willwood stuff is in-cockpit adjusters on oval-track racers.
Thanks All
