I have a 1993 chevy suburban K1500. My brakes went completely out. I have replaced the Master cyclinder, brake booster and calipers (front). I left the battery unpluged for 4 days and yet the brake and antilock lights are still on the dash. I do have brakes now but not power brakes. I have looked for a relay fuse but cannot find one. I have power to the head of the pump unit under the hood but it does not make it to the pump itself. Any ideas on what could be causing this problem?

the most common cause of this is either a sticking 4 way flasher switch or the turn signal switch itself.

SOURCE: no brakes after master cyclinder and booster replacment

To bleed the brake system open all the bleeders and let the system gravity bleed for @ 1/2 hour ensuring the master stays full. Then close all bleeders and starting furthest from the master (r/r) have someone pump the brakes 2-3 times,hold the pedal down, then open the bleeder,close the bleeder,and repeat untill there are no air bubbles and the brake fluid is running clear .Repeat for all wheels in this order R/R L/R R/F L/F ensuring master cykinder does not run empty. You cannot pump the pedal with a bleeder open you will be sucking air back into the system. Once you finish all wheels repeat to ensure there is no air remaining in system.
