Question about 1984 Jeep CJ7
If your brake pedal goes to the floor then the most possible cause for that is a leak in one of the brake lines!
is the brake light on?
check the brake fluid level and if it is low then have someone pump the brakes while you look under the vehicle to see if anything is leaking. pay close attention to the rear and if you have drum brakes in the rear look on the back side of the drum/backing plate at the very bottom to see if the fluid is seeping out there if so then you have a bad wheel cylinder.
if you inspect the whole system and can't find any leaks then the cause could be your master cylinder.
but before you can be sure pump the brake and if the pedal gets hard after the second or thrid time that is a sure sign of a master cylinder.
also if you have drum brakes and don't see a leak in the back you have to take the wheels off in the rear , remove the drums and inspect the wheel cylinders throughly by using a very small screw driver and incerting it between the wheel cylinder boot and the plunger to see if fluid leaks out and if it does then they will have to be replaced and are the issue. or the fuild maybe already coming out but didn't make it all the way down but you will see that right away when you take the drum of. it need to be completely dry in there.
good luck and if you have any more question please ask.

It sounds like you have air in the brake line(s). You need to bleed your brakes and that should fix your problem.
