MAINTENANCE INFORMATION
7.3 HYDRAULIC BRAKES
7.3.1 GENERAL
Although the hydraulic brake system is self adjusting, the
following require periodic attention:
7.3.2 BRAKE FLUID LEVEL
After every 50 hours of operation, check the brake fluid level
by removing the master cylinder cover.
IMPORTANT
Thoroughly clean the master cylinder cover and surround-
ing area before removal.
The master cylinder for the steering and stopping brakes is
located on the left side steering bar. Remove the cover to check
fluid level. Figure 7-27.
If the brake fluid is below this level:
1. Add only fresh clean SILICONE - DOT 4 BRAKE FLUID
(Argo Part No.130-108)) to the correct level.
2. Replace the cover making sure the rubber gasket is properly
seated before tightening the cover screws. Tighten snug
by hand only.
Figure 7-27. Hydraulic brake cylinder and fluid level
Do not overfill the brake master cylinders. Overfilling
can cause seal damage.
7.3.3 CHANGING BRAKE FLUID
Inspect the fluid for degradation (discolouration or particles)
during normal fluid level inspections. If discolouration has
occurred, the brake fluid system should be drained, flushed
and refilled with fresh brake fluid. If particles are evident in
the fluid, drain the system, flush and refill. An ARGO dealer
will perform these operations for you.
Spilled brake fluid is environmentally damaging. Proper
disposal is required.
7.3.4 HYDRAULIC BRAKE PAD INSPECTION
Inspect the brake pads after every 25 hours of operation. Worn,
glazed or contaminated brake pads affect the efficiency of the
brake system. To inspect the pads, first remove the firewall.
To remove the firewall:
Note: Remove floor pan first.
CLA
1. Remove the six (6) fasteners securing securing the firewall
using a socket and ratchet wrench.
2. Pull the firewall rear-ward moving the throttle cable clear
of the area at the steering column that it is routed through.
3. Lift the firewall clear of the driving compartment.
Brake Pad Inspection Procedure
With the firewall removed, both hydraulic brake calipers are
visible. Each caliper has 2 brake pads which are secured by
a single bolt fastener. Inspect all 4 brake pads.
Replace the pads when:
•
the brake lining material molded to each metal backing
plate is worn to 0.10" thickness. (Figure 7-28).
•
the pads are glazed and brake performance is affected.
•
the pads are contaminated with lubricant, and brake per-
formance is affected.
