If the brake fluid is below this level:
1. Add only fresh clean SILICONE - DOT 5 BRAKE FLUID
(ARGO Part No. 126-19) to the correct level.
2. Replace the cover on each master cylinder, making sure
the rubber gaskets are properly seated before tightening
the cover screws. Tighten snug by hand only.
Figure 7-17. Hydraulic brake cylinder and fluid level
Do not overfill the brake master cylinders. Overfilling
can cause seal damage.
Use only SILICONE - DOT5 BRAKE FLUID. Other
brake fluid is not compatible with ARGO brake compo-
nents and operating temperatures. Use of other fluids
will void the warranty and may cause loss of brakes or
steering.
7.3.3 CHANGING BRAKE FLUID
The inherent stability of Silicone DOT 5 Brake Fluid reduces
the need for frequent brake fluid replacement. 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, overhaul the master cylinder and the brake caliper
before flushing and refilling. An ARGO dealer will perform
these operations for you.

MAINTENANCE INFORMATION
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: HDi models: remove floor pan first.
1. Turn the firewall release catch(es) (located at the top of
the firewall) counter-clockwise 1/4 turn.
2. Pull the top of the firewall rearward moving the throttle
cable clear of the area at the steering column that it is
routed through. Push the rubber gear shift boot back into
the engine compartment.
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
cotter pins (Figure 7-19). 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 7-18).
•
the pads are glazed and brake performance is affected.
•
the pads are contaminated with lubricant, and brake per-
formance is affected.
To replace the brake pads:
Brake pads are easily replaced by removing the 2 cotter pins
securing them within the brake caliper assembly and pulling
each pad up and out of the caliper. See Figure 7-19. Pistons
have to be pushed back in first, to allow clearance for the new
pads. Slip the new pads into the caliper and install 2 new cot-
ter pins bending the ends over to secure the pads in position.
Pump the steering handle bar a few times to the left and to
the right to build up proper pressure and to locate the pads in
the caliper assembly.
