Please Help. 1990 Toyota Celica

seems that the brakes are still soft and will depress tom the floor slowly. have bleed the brakes at the cylinders, seem there is still air in system? how do you bleed an abs system?

I cannot find much about the process on the net, but it does not look too hard, just a pain to remove the wheel well to get to the belts. Any resources that may help? Would a Maxima manual help? The rest is a vent, so ignore as you see fit :) Here is a perfect example of a shop trying to take advantage of a woman (foriegn student to boot). She brings it to a mechanic for the state inspection, she fails for brakes and tries to tell her an all wheel brake job will cost at least $400, probably more. He also tells her the serpentine belt is bad, that will cost over $800 (which would figure about 10 or so hours labor if I calculate correctly), and a CV joint is going bad, another 2K. When I called, he refused to give me his estimates and would not put it in writing for her. I did check and replace the brakes (including a lug stud he cross threaded during the inspection). I would like to tackle the belts, but do not want to bite off more than I can chew. Have a great day!
