A banjo fitting is a specialized type of brake fitting
used to connect a brake hose to a component at a right
angle, Figure 9-27. These fittings are frequently used to
connect brake hoses to brake calipers. They consist of a
connector with a bore through it, a bolt with a fluid pas-
sage drilled in it, and two copper crush washers. A copper
washer is placed on each side of the connector and the
bolt is installed through the bore and tightened into the
component. Fluid can travel from the hose into the con-
nector, through the hollow bolt, and into the brake com-
ponent. The copper crush washers prevent the connector
from leaking.
