Same 65 f600 brakes
Same truck and the same ill-fated brake system. While trying to track down the problem of the brakes locking up, I pulled the master cylinder off to look and see if it had a check valve or not. It didn’t, however I did find a lot of fluid in the dust boot, although I’m sure one thing has nothing to do with the other. So I went to return it for a replacement and they new of all the issues I’ve had with the brakes so the owner said to bring in the hydrovac and that they would replace it as well. So at that point I decided to replace the rest of the steel lines and blew out and flushe the entire system. Anyway, to get to the point, I was starting to bleed the system when I noticed the fluid coming back through the master with a steady stream almost shooting up and out of the cylinder. Just a guess but I’m thinking another bad master cylinder. The fun is truly fading fast on this thing…….

Thanks Ray, I’ve gotten to the point where every thing on this brake system has me second guessing myself. I said to my wife this morning that I thought the fluid mite act like that.
Thanks again, sometimes you just need someone reinforce a thought…..

You can use a pressure bleeder on C-models. BUT you have to push the brake pedal part way down and block it with a pipe between pedal and drivers seat. Remove hydra-vac bleeder and connect pressure bleeder.
Bleeding C-model brakes can be easy or worse than you can imagine. You never know until your done.
Two more cents worth, Dennis..........

Thanks Dennis, are you talking about one of those hand vacuume pumps?? I have one however it's still new in the box, never used the thing... Maybe I should give it a try???
Thanks again
I'm ready to try anything at this point. they are just brakes. I can't see why I'm having so much trouble...............

I also have a vacuum pump I've never used for brakes, only to check vacuum controls.
The pressure bleeder is a pressurized tank with brake fluid in tank. It's a way to bleed with one man and no pedal pumping. Just mentioned it if you have trouble getting the air out it's another option.
Another method:
On any vehicle I bleed, I open the bleeders and keep the master cylinder full. I leave all the bleeders open until I see fluid flowing. Sometime thats all I need. Don't have to reset any differential valves that way either.
None of the above may be needed just options.
Best to you, Dennis...

Thanks Dennis, In the beginning I had problems bleeding the system. then had problems with brakes looking replaced the master and vac again and now i'm having problems again bleeding the system again and now I see the master is leaking into the dust boot again. also seems as though the stroke is shorter than the last mc i had.......
