Question about 1986 Ford F150 SuperCab
Since there is no loss of fluid we can rule out any leaks. A poor booster would make you apply the brake much harder to stop. So somehow you are not developing the necessary pressure for the brakes to function. The pressure is developed by the master cylinder seals. You can get a rebuild kit or a rebuilt master cylinder but the real pain is bench bleeding the new one. Luck to you.

Check your brake booster vacuum pipe for leaks otherwise it sounds like your brake booster has failed
