Brake & Inching Circuit Bleeding
The purpose of bleeding the brakes is to remove any entrapped air in the brake and inching system which would make the
brake or inching pedal feel "spongy" and allow the pedal to travel without proper build-up of hydraulic pressure, thereby
losing effective braking and inching.
Normally, a minimum of brake bleeding will be required. The combined brake and inching circuit is designed to place the
brake fluid reservoir at the highest point in the circuit. This ensures that the major part of any air that has entered the
system will flow upwards and vent into the reservoir. The recommended brake bleeding procedures outlined below are
intended to dislodge and remove any entrapped air from the circuit.
NOTE
To
perform
this
service
procedure,
it
is
recommended that you first:
•
Park truck on a level surface
•
Return all controls to neutral and turn
ignition key switch OFF, unless otherwise
directed.
•
Remove key from switch.
•
Apply parking brake and block drive
wheels.
GPX Model TA18 Transaxle
Bleed brakes with engine off (not running). Check
frequently and keep master cylinder reservoir filled
during bleeding.
NOTE
Use SAE/Type DOT 3 Heavy-Duty brake
fluid.
