Jerky braking

I have a 2003 F-150 4x4. Only 20,000 miles on it because it was in storage
for a year and I either walk to work or take a bus.

Periodically, I feel a pulsation or vibration in my brake pedal every time I
stop, particularly when stopping from high speeds. But the brakes seem to
work fine. Some internet research indicates a warped rotor or an
out-of-round drum. My last two oil changes and 'brake inspections' have
indicated that both front and rear brakes are fine, but of course they never
took the truck out for a test drive so obviously the sensation I am feeling
cannot be detected visually.

Gee, I hate to get break work done at only 20,000 miles but does anybody
detect anything really wrong here? Am I playing with my life? It has been
doing this for several months now. Would the storage of year and not using
the breaks have and adverse effects on them?

Doug,

It would take me an hour to find the TSB to see if it is applicable to your
truck, but there is a TSB about undersized brake rotors on the F-150's and I
believe your truck to be included. You might check with your local dealer to
see if that might be your concern.

As for the storage concern, I dont think so. It would allow rust to build
up, but that would just be worn off rather quickly. You might be witness to
false ABS activation though. I would have a mechanic drive your truck and
make sure that isnt what is happening.
