Meaning the back drums and front calibers, I also have replaced the booster, master cylinder, & the ABS block on the frame for the back brakes only. I used the Haynes auto manual & procedures to bleed the system properly as well as installation. I have got a good petal to start with but it will leak down if I hold it down for a short period of time so I'm totally confused on what is going on here any suggestions will be greatly appreciate.

Then you need to know WHY the ABS light is on.. Scan test, don't guess!!!.. Does it have RABS only??.. I use block off plugs on the master cylinder line ports to TEST master cylinders!.. Can be made from 2 old lines crimped, soldered or brazed shut!.. That will tell if problem is master cyl or not!!!... Can also use a pinch off tool to clamp closed the rubber flex hoses for additional testing...if you are familiar with testing procedures. good luck with it!
