Hey all. Just got my rear brake line replaced and want to give it a complete flush even though the shop said they did it but, fluid in master still looks dirty. Are there any special procedures about bleeding with the ABS system on the trailblazers? Or just the basic open bleeder and hit the pedal. Want to replace as much fluid as possible. Also, do I need to push the pads in and flush the calipers themselves or not necessary?
