Brakes (A5)Question 60 of 120
When bleeding a conventional hydraulic brake system, the general rule is to bleed:
a.All wheels at the same time
b.Only the front wheels
c.Starting at the wheel nearest the master cylinder
d.In the sequence specified by the manufacturer, often longest line first
Explanation
Manufacturers specify a bleeding sequence, frequently starting at the wheel farthest from the master cylinder, to purge air effectively. Following the correct order and keeping the reservoir full prevents introducing more air. Some ABS units require a scan tool to bleed fully.
