    1998 F150 with ABS. 150K miles, brake system was flushed every 2 years. And no, this problem did not occur just after a brake flush.
    Problem started at about 140K miles. The front brakes were intermittent, i.e. maybe once every 2 weeks or longer, they wouldn't work for 1 stop i.e. rear brakes only - thats a real thrill!!.
    Then everything was fine for another 2 weeks to a month, then no front brakes again for 1 stop.
    No error codes were set. This was checked after the front brakes failed and before the iginition was turned off.
    I now drive a Tundra.

    1990 Chevy Lumina with 3.1 V6--as faithful and unexciting as an appliance until the brake pedal hit the floor around the 90K mile mark. Luckily, we were alone on the road. Brakes could be pumped back up and worked fine the next day on the way to the local Firestone auto care shop. They checked out fine, but went out again a couple of days later. We took the car back and had the brakes redone. They went out again a couple of days after that. We were STILL lucky that we didn't hit anyone or anything. After we replaced brakes at all four corners to the tune of a few hundred dollars, someone at Firestone discovered that the apportioning valve for the diagonal braking system (located IN the master cylinder) was bad and replaced it. The braking maladies were finally cured.
