I am getting fed up, i am not used to old brake systems, and its killing me. I had to replace a brake line inside the driver front drum, it was broken, and no brakes. replaced it, and i am getting no pressure at all in the brakes after bleeding all four corners, the MC was pulling fluid, and fluid squirts up when applying brakes. Help a newbie out on these old brakes, what gives?
Ok you are bleeing both upper and lower cylinders aren't you? Try bleeding the upper first then the lower and go back to the upper again.Sounds like air in the system for sure. The way I'm reading your post you are moving fluid through the system and are having to re-fill the M/C right?
you are correct, i am doing both, the rear has a 10bolt, so there is only one bleeder, and they seem to be ok. I believe i started with the lower first and then went to the upper. the upper started to push the pad out a bit, but nowhere near enough to hit the drum. maybe i should go get some of those cheap bleeder valves.
A couple of tips from experience with my 47 & 49 Plymouths 1. Fill the MC up and open valves at all four wheels, once you have fluid coming out in this order close the RR, LR RF LF 2. Pump up pedal, open RR, PUMP LR, PUMP RF LOWER, RF UPPER, LF FRONT LOWER LF UPPER. 3. ALSO belive it or not make sure the shoes are adjusted correctly, out of adjustment can and will impact the pedal
Those 6 wheel cylinder setups are a *******, my '55 Dodge has the same ****. Make sure to swap out your original master with a newer dual chamber one. I used a '73 Dodge Dart master, bolted right to the firewall, the pushrod was too long but they are adjustable. On that goofy system, it's not worth taking a chance, because one leak and you've got no brakes.
