If a new master cylinder was put and if it is not bench bled first, it'll
take forever to bleed the entire system. Always bleed the system starting
at the farthest wheel cylinder first--do the right rear first, then left
rear, right front, then left front. I just went through my brake system
and man what a difference all new parts makes. --wayne
