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 covers.
IMPORTANT
Thoroughly clean the master cylinder cover and surround-
ing area before removal.
The master cylinders are mounted tilted slightly back. When
adding fluid, fill until the shallowest end of the fluid level in
the well is approximately 1/2" from the top lip of the master
cylinder (Figure 7-17).
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.

MAINTENANCE INFORMATION
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 may not be compatible with ARGO brake compo-
nents and operating temperatures. Use of other fluids
will void the warranty.

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 nor-
mal 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.

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:
1. Turn the firewall release catch (located at the top of the
firewall) counter-clockwise 1/4 turn.
