Why do I have to change the fluid in my ABS brake?
Bleeding involves flushing the air pockets out and replacing the old fluid. The old fluid needs to be changed because polluted fluid absorbs air moisture and lowers its boiling points.
Can a non ABS brake pump bleed blood?
An anti-lock braking system (ABS) is less tolerant of air bubbles and polluted fluid than a non-ABS system. An ABS hydraulic pump uses thousands of psi to push brake fluid through tiny valves. Contaminated fluid can easily damage the valves and pump, so you should never dally when the system needs bleeding.
