We live in Mexico Ny and it has been cold, could water be trapped, but I put so much fluid through it and bled the brakes out, nothing is discolored and nice clear fluid with air bubbles bleeding up to the front MC like what you had mentioned. After I bleed them and push on the brake pedal, I have NO pressure Today, while it was warmer out, I bled the rear brakes again, had good pressure without the engine running as soon as I started the engine, put my foot on the brake went straight to the fllor, light came on and NO PRESSURE....Brakes at bottom of pedal. Temp 50 today. Ohter than that it has been below freezing daily. Thanks for such a rapid reply.

U mentioned after U started the Jeep the pedal went to the floor? Do U have power brakes? If so the booster might have went.

Thanks for the fresh insight.....I am going to try your advice tomorrow. yes on the power brakes, but I haven't lost the vacuum would that make a difference. I would like to keep in touch with you on this issue.... We have some decent weather right now and I need the jeep for the snow...Just bought it about a month ago, but have had CJ7's for about 13 yrs. This is a challenge.

My '79 did the samething w/out fluid loss & the booster would hold but bleed down & I would loose pedal. Just a thought but look @ your rear wheel cyl first, sounds like the problem.

as you suspected....the passenger side rear wheel cylinder was fully seized up and leaking small amt fluid..not visible outside of the drum and the driver side was completely seized up and no leaks found...also, found the emergency brake was trashed....another project to tackle later..just purchased the before X-mas so still learning stuff about it. Hey.....thanks for the advice...appreciate it. I was reading alot of other different stuff from this site and would be interested in a link to CJ7's esp...specs on 1978. Sounds like the right person to ask.
