While driving the truck breaks all the time and the disc is extremly hot red hot so i stoped the truck can any one help me regarding this problem the garadge shop say its an abs problem please help me

 

It might be your ABS module. Try removing the ABS fuse NBS is the 112 / 40 AMP, OBS is the 102 / 50/20 AMP. See if that does anything.

 

Check the flexible rubber brake hoses. When they get old, they can collapse, keeping the fluid from returning.

 

Actually, after re-reading your post and seeing glc's response, it might be your rubber brake hoses. Can't hurt to check it all.
