Brake Fluid Level (Service Brake Master Cylinder)
The ARGO HDi is equipped with a hydraulic
handbrake system. This consists of an
independent set of hydraulic brake calipers and
brake discs. The master cylinder is mounted on
the left side steering bar. The master cylinder
is not serviceable nor replaceable. Complete
hand brake/master cylinder assembly must
be replaced. Photo A
Monitor the hand brake uid on a regular basis. The master cylinder well is translucent and
the uid level is visible to the eye without removing the cover. Ensure the level is to the
“top” level mark. Photo A. Inspect all brake hoses and brake ttings at both hand brake
and hydraulic calipers for any signs of brake uid leaks.

IMPORTANT
If the cover needs to be removed to replenish or service the system, thoroughly clean
the cover and surrounding area before removing to avoid any contamination to the
brake system
The inherent stability of Silicone DOT 5 Brake Fluid reduces the need for frequent brake
uid replacement. Inspect the uid for degradation during normal uid level inspections
(see Brake Fluid Inspection). The brake uid system should be drained, ushed and relled
with fresh brake uid if any abnormalities are evident. Perform the servicing procedure,
Changing the Brake Fluid. If particles are evident in the uid, drain the system, overhaul
the master cylinder and the brake caliper before ushing and relling. Perform the Servicing
Procedure, Bleeding the Steering Brake System.
NOTE
Spilled brake uid is environmentally damaging. Proper disposal is required.
Hydraulic Brake Pad Inspection (Steering Brakes)
Inspect the brake pads after every 25 hours of operation. Worn, glazed or contaminated brake
pads affect the efciency of the brake system. To inspect the pads, Perform the Servicing
Procedure, Remove the Firewall.
With the re wall removed, both hydraulic brake calipers are visible. Each steering brake
caliper has 2 brake pads which are secured by cotter pins (Figure 1). Inspect all 4 brake pads.
