My ABS light is on. I have replaced everything brake related and cannot figure out what is next. I've put in a new master cylinder, power booster, drums, wheel cylinders, pads, shoes, adjusters, springs, and calipers. What is left?

ABS proportioning valve, ABS wheel sensor or related wiring, you replaced all the mechanical parts but the ABS for the most part is electronic.
 






Also, after all ABS problems have been resolved, it will take approx 25 miles of driving or 50 ignition cycles in order to clear the ABS trouble codes. Alternatively, disconnect the battery, let the PCM reset to factory settings and then let it relearn it's proper operating characteristics. This may take up to 100 miles of drive time for it to relearn all the settings.

I almost did the same thing but i was throwing $100 wheel bearings at it. After replacing everything on my '04 i could think of i went and got a code reader. Hooked it up and got an ABS code of C1440, I had overlooked the master cyl. Switch, cheapest part too $20 later it was fine.
 






Fixxxer, I think the first part of what you said will be the problem. I've driven it over 200 miles since the mechanical replacements and the light is still on. I thought maybe it was on because one of the adjusters was missing and a drum was cracked. I think I'm just going to remove the bulb from the dash :D

jrford, I actually own a code scanner, but can't figure out what to do with it. I'm not familiar with the coding. I've read and re-read the manual several times but I think it may be the wrong one. The port doesn't match up to the one under the dash. (Which I'm finding out that Ford isn't the greatest for putting wiring in that actually matches accessories.)

Thank you both for your inputs and suggestions.

14 sensors that can post up to 50 codes . .Front L/R ABS sensor, Rear Sensor, Brake Pressure sensor for cruise, just to name a few.

the code reader should have a plug next the parking brake release lever, i thought it was 15pins. If what you have don't fit there, it might be the wrong one, whats the model number?

If you can't get yours to work, then a small brake shop may read it for you if they have the right tester (one that reads Ford ABS codes), they only charged me like $45 compared to the dealer who wanted $85. . .
 






The code scanner I have is by Sunpro CP9015. It is supposed to be for Ford, Lincoln and Mercury from 1981-1995. It has 3 prongs together, and then another prong off to one side.
 






I found an alternate port and the blasted thing won't code for me. The manufacturer says that if it doesn't code something needs to be fixed first. A lot of help that is!
*I called the manufacturer and oh my God how ignorant can people be!!! Long and short of it, this code scanner does nothing helpful and the techs at Sunpro are even less helpful. Thanks to you guys that offered your input on this matter. I'm going to just unplug the light, considering the brakes work excellent.
