Johhnny is the ABS light illuminated on the dash after the vehicle starts to move? If it lights on start up and then goes out the ABS diagnostics have done their job....checked all the wheel speed sensors and they are ok.
If the ABS does not illuminate at all, then it it has either been diabled of the fuse is blown(can also still illuminate the light but will stay illuminated).
Check this first because if your ABS isnt working you could have large troubles.
After that you still need to check the condition of your brakes. Typically if the vehicle pulls to one side under brakes the OTHER side is defective and this has nearly infinate reasons.
Check there are no external leaks of fluid from calipers or wheel cylinders this can lubricate the brakes and reduce efficiency.
The discs can be glazed or pads worn out but the most common with a 4wd that has been driven offroad is the sliding calipers are now not sliding and you have reduced that caliper brake efficency by 50%!
I cant imagine that the 100 has an ALB to proportion for increased load, usually that the domain for utes but it may...still doesnt explain the pulling that would just reduce overall brake efficiency.
Sort the ABS issue or at least eliminate it then sort the brake issue and I believe you are prob just due for a reline, bleed and free up any calipers.
All the best
Matt.
