ABS Light and Brake Light both ON: Need Help
1997 FORD F-150, 4.2L V6 4x2 with rear ABS.
Work done on it so far: Replaced plugs, fuel filter and prake pads. Intake gaskits were replaced by previous owner in 2008.
OK Replaced front brake pads, re-bled all four wheels starting from Rear Right, the rear left. Blead 10 or 11 times each until clean fluids appeared without any bubbles.
Results: About 5 percent improvement but still spongy and ABS and brake lights still ON. I don't know what else to do beside taking it to a mechanic.
Please advise.
Thanks

Update:
After searching this forum some more, I stumbled upon a 250 thread with the same problem. I knew I don't have front ABS sensor because I did'nt see any. So I checked the rear one and sure enough, it is on top of the differential. It is connected to a wire and 12mm bolt facing towards the front of the truck. I pulled it out. It takes some patient to pull it out. So I checked for resistance. It is magnetic and it read 1.11 so I cleaned it with electrical cleaners and then used high quality silicon spray on the connector part and installed it again.
Fired up the truck and no more ABS light staring at me. Hopefully this solves it. I will update after I drive some more.
So here is my experience on these Fords thus far. People tend to drive them without usual TLC. Up-till now most of my electrical problems were solved with either WD-40, electrical cleaner or silicon grease. It appears the grease used by Ford is not of a high quality and uses its function after 20 years.

msk59 is correct. My '99 2WD XL had the same thing. I swapped out the speed sensor on top of my rear diff a few years back and haven't seen the light since. Replaced it with a new Motorcraft sensor, easy fix.

Well I spoke too soon. The light came back On so this evening I replaced the ABS Sensor with a new one and guess what, the light came back on as soon as I test drove it.
Now the switch on top of the brake master cylinder has some brake fluid in it and the Cruise Control does not work.
Question: Should I go ahead and replace it with a new one along with the fuselink?
I don't know what else to do. The brakes after bleeding two times are still spongy. Please help.
Thanks very much

OK replaced the brake master cylinder switch along with the wiring harness provided by Ford. Also replaced the ABS sensor but nothing works, the light still comes on. Both brake light and ABS lights come on at the same time.
Spoke to a guy at Ford dealer and he said that unplug the battery negative for about 5 minutes to reset the code or erase the code. Did that but no luck:
