The Stovebolt Site Forums The Parking Lot Big Bolts source for brake springs

one guy thinks he found the Raybestos part after crossing your number to Wagner then Raybestos. We ordered the set and we will see. The spring is about 3-4 inches long. The GM part number is 3694516. The Chevy house gave me that but of course it was discontinued in 1983. You know, the great thing about John Deere Tractors is that I can still go the the John Deere house and get parts for my 1959 730 two cylinder tractor which I still use for farming. Considering their circumstances maybe GM ought to take some lessons. I reallly appreciate y'alls help. Any ideas on building an inexpensive pressure bleeder? As a matter of fact I would like to build an external fluid resevoir so as to make it easier to monitor fluid level. A simple vacuum pump doesn't do the trick nor does manual pumping. The shop manual says a pressure bleeding system is required on hydovac assisted brakes.
