Ok , on my free truck, I was driving along and had to hit the brakes a little hard and the back wheels locked up and smoked the tires, I looked and saw the ABS light on the dash, is this a fuse or something deeper?

 

2 or 4 wheel ABS?

The rear abs (2 wheel) doesn't work very well......

 

Its a 4 wheel drive truck, how would I know if it is 4 wheel ABS ? where do I check?

 

Check and see if there are wires for the front wheel speed sensors. If there aren't any wires, then you just have RWAL.

 

No wires going to the front wheels, and I dont see any going to the rear, is there a junction box somewhere that is causing the wheels to lock up?

 

May not hurt to inspect the rear brakes.

 

took off the brakes and the pads look great, now the e brake doesnt work but I think the cable is stretched or broken, I will check that out, but still doesnt fix the ABS light on the dash lit up and the rear brakes locking up

 

Check the sensor on top of the diff. They tend to fail. About all you can do is replace it.

Your speedo works properly, does it not?

Also: What year is your truck?

 

Speedo works fine, its a 1997 1500 extracab 5.9 gas engine

 

Ok, might just replace that rear wheel speed sensor then, and it *may* solve your problems.
