i had a hill holder in my '63 chevy "bad ass" biscayne. it was called the parking brake! That was a neat concept though. Nate, did you ever have to work on one? Didn't it use some kind of sensor to automatically apply brake pressure until you let the clutch out enough to partially engage it?
We finished up a 1930 Plymouth "U" model early this year and one source we used was allpar.com and also Roberts Mopar Parts. There are several suppliers listed in Hemmings. Our forklift we use at work has a flat chrysler motor and they were used in dozens of industrial applications. Not many years ago and maybe yet the "donkeys" they use to pull aircraft around on carriers had this old engine. Steele Rubber is a little pricier than some but they had rubber for the 30 Plymouth. Also, Metro in Minneapolis will match up extruded rubber design if any of your old windshield, back window, or other rubber is in good enough shape they can get a cross section profile. Hope this helps some, Good luck; Evan
ThankYou Evan, finding more good sights all the time. And Nate I ordered Vintage Truck Magazine, that rebuild is seems perfect. Thanx Tim
The Hill Holder was an interesting deal , a ball bearng in a horizontal channel that would roll back and hold pressure in the hydraulic brakes untill you let up off the clutch pedal , it really worked , was linked to the clutch pedal so it didn't comeinto play unless you were : A. facing up a grade and B. had the clutch pedal to the floor . Giro-Matis were cool too and way ahead of thier time ~ you shifted once and it shifted twice , giving you _4_ forward gears , this way back in the late 40's no less but it allowed flathead powered cars to really zip along the open road . -Nate
