12-10-06 Replenishment of Brake Fluid
In order to assure proper brake action, it is necessary to have
positive transfer of hydraulic pressure through the system.
Any air trapped in the system must be removed. Follow the
procedure described below using a bleed tank (1, Figure 1):
1 Remove engine cowlings as per Chapter 71-10-00.
2 Remove fluid reservoir filler plug and screw a clear plastic
hose with appropriate fitting into the filler hole at the top of
the fluid reservoir.
3 Remove bleeder fitting cap (3) of the wheel brake assembly
(2).

4 Be certain that the bleeding equipment to be used is abso-
lutely clean and is filled with brake fluid that conforms to
Specification MIL-H-5606, (refer to Chapter 05-20 Lubri-
cation Charts) and is uncontaminated.
5 Maintain an adequate supply of fluid during the entire op-
eration. A low fluid supply will allow air to be drawn into
the system.
6 Ensure master cylinders are in neutral position.
7 Attach the connector hose (4) to the bleeder fitting.
8 Turn the bleeder fitting 1/2 rotation to the left for opening.
