Been awhile, was last working on E150, which I致e since converted into camper. I used to have 68 f100 but have recently purchased 1968 f250. C6, Dana 60 pegleg 3.73, LWB, Camper Special from original owners youngest son. His youngest son has been buddy for decades and cut me very fair deal. It is a 360 2 barrel truck with underdash air from Monkey Wards (for us seniors). Air doesn稚 work my buddy says but compressor spins. Although it is manual steering lwb f250, it does have power booster to the 4 wheel drums.
It has around 170k long distance miles, as they only used for long camping fishing and hunting trips. The Dad raised his kids to all be outdoorsman in this truck, and his camper my buddy retains. It was parked due to split brake hose and now the power drum master will not release any brake fluid to the front wheel cylinders. So, I知 trying to recall, how you hold in something to force the brake fluid and recenter the valve or something? If bleeder valves completely loose and been that way couple weeks, with no fluid leaving master cylinder, the valve has to be recentered ?

also, has anyone ever had any luck removing the big old rivets factory installed that retain radius arms to frame from under truck with radius arms in place? I have to do radius arm bushings and am older and weaker and would be nice if I could break the big old radius arm nut loose, and get to the rivets with a dremel or ? And replace all to hold radius arm bracket to the frame with grade 8 hw. I rebuilt couple of front ends been awhile and memory is vague and my strength gets less so I have to work smarter since I work alone and have no helper. I recall doing radius arms where drop I beams and that got tough to wrestle back up alone back then. Now I doubt I could do it.
thanks folks.

 

Torch the rivets and punch them out.

Radius arm nuts, wire brush the threads, soak with PB'laster and use a 2ft breaker bar.

 

Well I worked up some old man courage and have cotter pins, radius arm nuts off both sides. Not having torch, I’m using side grinder to work down the large mushroom shaped rivet heads down on exterior frame, Then using air impact to knock on through to inside and out. Not going fast but I’m in no big hurry. Got heads ground off two rivets and one knocked out, so I’m learning and getting there.
