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uid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
uidlevel.Figure7-27.
Ifthebrakeuid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 uid level
Do not overll the brake master cylinders. Overlling
can cause seal damage.
7.3.3 CHANGING BRAKE FLUID
Inspecttheuidfordegradation(discolourationorparticles)
duringnormaluidlevelinspections.Ifdiscolourationhas
occurred,thebrakeuidsystemshouldbedrained,ushed
andrelledwithfreshbrakeuid.Ifparticlesareevidentin
theuid,drainthesystem,ushandrell.AnARGOdealer
will perform these operations for you.
Spilled brake uid 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aecttheeciencyofthe
brakesystem.Toinspectthepads,rstremovetherewall.
To remove the rewall:
Note: Remove oor pan rst.
CLA
1. Removethesix(6)fastenerssecuringsecuringtherewall
using a socket and ratchet wrench.
2. Pulltherewallrear-wardmovingthethrottlecableclear
of the area at the steering column that it is routed through.
3. Lifttherewallclearofthedrivingcompartment.
Brake Pad Inspection Procedure
Withtherewall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aected.
• the pads are contaminated with lubricant, and brake per-
formanceisaected.
