Question about Ford F-150
First I would suggest to check the front rotors. Before replacing, remove the wheels and give them a good inspection. If you can get a hold of a magnetic base with a dial indicator, then you can check for warpage.
Next please check the rotors but there is a posibility that it could be your wheel bearings. to check jack front end up and try to shake wheel top to bottom if it does shake then your wheel bearings need replacin.
The first step is to insolate the braking system to determine if the rear brakes or the front brakes are the source of the shake. Once you've found which end of the vehicle's braking system is causing the shake you have to isolate each wheel. I've had brand new brake rotors and brake drums that were warped or had excessive run-out right out of the box. That is why you have to take the time to isolate just from which brake the shake is being caused by. Once you figure out which wheel brake rotor or drum may be the problem don't go right to the parts store yet for a replacement. Inspect the mounting surface that the rotor and/or brake drum set on. There can be no rust. All it takes is one flake of rust between the mounting surface and the new brake drum or rotor to cause a good amount of run-out, resulting in a shake when braking. So if the vehicle started to brake shake after the brake work, it is likely that you have a defective or damaged brake drum or rotor.

I have a 99' f150(2wd) that has the same problem, front end shakes while braking. I changed the right(passenger) side upper control arm( about $50 for the part), checked the brakes and rotors, and changed the left wheel bearings(inner and outer) but I still have the shaking.
But while the truck was up on jackes I tried to turn the wheels by hand(like I was making a turn) and i noticed that the "BALL" joints on the idler arm and the tie rod ends where very lose. the entire steering bar would twist when i put any pressure into turn the wheels. I'm thinking this may be the cause of the shaking. Tie rod ends run abou $30 each and the idle arm cost between $50 and $250, depending on which style is on the truck.when i get some extra money I'll start replacing the componets one by one. I'll repost my resaults when i do.
