When I first start off in my 1989 FJ-62 the break pedal is soft and goes to the floor. Once I pump it once then it feel like there is pressure in the line and resistance at the pedal. Is this normal, or is this sign of a leak or bad brake cylinder? It seems to have just started this since it got cold.

Could be. Get under your truck and check for leaks. If no leaks are found Id'e bleed the hell out of the brakes and push all the old fluid out and bleed till all the fluid is clear. Try this and recheck your pedal if it's still soft it may be your master, but it sounds like air to me. If you happened to let your resivior get to low you may have air trapped in your master cylinder, you may have to bleed it as well.

Brake fluid is very stable. It typicaly does nto just go away..
So, if all of a sudden you have air in your lines, most likely there is an issue with your braking system somewhere.
Start looking for leaks. Check the master first of course..

Ditto on the posts from Mace and BGarcia88FJ62, there is definately something out of the ordinary and needs fixing.
Don't forget to bleed the Load Sensing Proportioning/By-pass Valve after you bleed the brakes first. If you don't know where this valve is, its just above the rear axle. Follow that rod that is connected to the housing to the valve. There is a bleeder plug just like the wheel cylinders.

One of the things that I have noticed over the years when it comes to mushy Land Cruiser brakes, is it many times can be traced to the front wheel bearings being loose. This allows the rotors to push the pads and pistons back into the caliper resulting in higher than usuall pedal travel the first time you step on the brakes. Obviously you want to do the easy things first, like bleeding. After that, put a jack under the front axle and see if there is ANY play in the wheel bearings. It's easier to feel with the wheels on.
