Well the ole girl has been sitting awhile, and I find no pedal on the brakes,(or kinda to the floor !@#$&%! LOL !) Thats better than finding out on the road. I need to move it back here, 30 miles or so.
Question is, or I suspect, diaphragm in the frame mounted hydrovac unit, or what ? I bled the brakes starting at the furthest cylinder and never got any real pressure, sputtering before a solid stream out of that one, refilled the master cylinder, did get a small stream out of the next over, on the rear axle, but no pedal, I'm thinking its the hydrovac assist. There is an air filter or I believe thats what it is in the cab up by the top of the seat with a hose, I do not hear any air moving, you could before, hence my suspicion of the diaphragm, I've never worked on one of these on the frame, but plenty of other similar brake systems with the booster on the firewall behind the master cylinder. Master cylinder was low, so I'll bet a wheel cylinder is leaking, but I saw no sign, so its slight, I used to have to bleed them periodically.
I'm not sure how to ID it on the truck, but it appears to be similar or just like this one in the photo below and looks old, though been fine, age, sitting etc. It appears that I may have to match up some "plumbing" maybe there is some marking on it, its rusty, I did look up the one below and found it listed by Haldex, but again, looks the same, have not confirmed, hopefully these are not outrageous in price LOL !
I'm assuming from what I have looked up on the web, you would replace it, could rebuild if one wanted to thought I saw kits, but given its a brake component, never been inside one, the previous may be wiser than the latter LOL!
Ideally, I really want a double reservoir master cylinder instead of the single, so at least you have one axle with brakes if a hose or line was to rupture, anyone know how to do that on these old trucks.
I don't use it much, nor do I ever put any weight on it, its just handy to have though, might be time to go through the brake system and know they're done.
PS I do have the factory service manual, will have to read up.
