Hey all, got another question for you that have maybe had the same thing happen or just now what it Today I was driving in town, went to stop at a stop light and the Anti-lock brake light started flashing what looked like a code...flashed (13)times I think it was and then solid burn. I had a to go to HD and when I started the truck to leave the light was no longer flashing or burning, untill the first stop light. I still had some running to do, so I tried to pay attention to it. I did notice I blew a fuse for turn signals and such (pulled trailer last night and plug came apart when I unplugged it) so I replaced the fuse thinking maybe it had something to do with the light.
On the way home it did not burn again untill the brakes were applied, but I did notice that a light braking did not turn it on. The light only came on when the brakes were applied with some pressure, nothing real hard but more than a feather touch. Light goes out every time when the truck is shut off untill that first stop, then burns untill key is shut off.
If anyone knows if it a sensor or what, I would appreciate it so i can fix it!! thanks

Brake pedal stiff? Vacuum pump? Can't remember if the light comes on with it or not, but if it is on its way you may only have one or two brake apps before you loose power brakes. Take the big vacuum hose off the brake booster with it running and see how much vacuum you have, should be a hole lot.
