How do I go abouth flushing the brake system on my 2000 Blazer 2WD. I have a press bleeder available if needed. Do I need a scanner to flush the system if there is no air in the system?

 

should be able to do it by just doing the brake bleeding procedure. have someone pump the brakes a few times and hold it and crack the bleeder open then close it and repeat. go around and do each bleeder one at a time til you get the clean fluid out. make sure you dont let the master go dry though. and if you live in north where salt is sprayed down, start spraying down those bleeders asap they tend to break off

 

+1, also work your way from the furthest wheel away from the master to the nearest.
