My Mom had the same problem with her truck.. It is due to a recalled part that is on the brake master cylinder
Not a major job Disconnect brake lines Disconnect electrical level sensor Remove mounting bolts BENCH BLEED NEW MASTER CYLINDER PRIOR TO INSTALLATION

A Ford dealership would be the best place to find a master cylinder for a Ford F150. Parts Geek, Parts Train, and eBay also have master cylinders for a Ford F150 for sale.
It is on the firewall, drivers side, next to the vacuum brake booster. It is the small reservoir closest to the fender.
The clutch master cylinder is under the hood, drivers side, on the firewall. It is between the brake master cylinder and the drivers side fender. The cylinder is very small in comparison to the brake master cylinder. It goes through the firewall and connects to the clutch linkage under the dash.
you put the brake fluid inside the master cylinder
Sparkplugs... Give it a tune up.
no you dont have to---BUT its adviseable
I believe that is called the power brake booster
Best answer I've found is here (I have a 2001 F150): http://www.clutchwizard.com/fordtruck.htm Basically the problem is that the master cylinder is at the wrong angle to bleed the system completely with the master cylinder attached to the firewall. You have to take the master cylinder off the firewall and detach it from the clutch pedal, then tilt it to get the air into the line. After that, you bleed it in more or less the usual way, with a helper operating the bleed valve, but pushing the piston directly instead of pushing the clutch pedal. The alternative is to assemble the whole system off the truck and bleed it on a bench. Good thing they made the master cylinder and the brake cylinder out of PLASTIC, and put the slave cylinder INSIDE the bell housing, huh? (My slave cylinder went at less than 60K).
The Ford F150 was produced from the years 1948 to present in the United States. The cylinder 8 in a 2002 F150 4.6 is located against the driver side firewall.
