12-80 BRAKE SYSTEM – SERVICING PRACTICES
LEVER TOE SYSTEM
General
Overall oil quantity in the brake system is 200ml (order of magnitude). Fluid is drawn from
the reservoir by the brake cylinders to maintain the fluid volume required for maximum
braking efficiency.
The oil level check procedure is addressed below; refer to Chapter 32 for bleeding and filling
brake system procedures.
APPROVED HYDRAULIC FLUID SPECIFICATION:
MIL-H-5606, (e.g. AEROSHELL Fluid 41)
The brake system operation with low oil level could affect the brakes’
performances and could cause permanent damage.
Make certain that hydraulic fluids and fluid containers are protected from
contamination of any kind. Dirt particles may cause hydraulic units to become
inoperative, cause seal damage, etc. If there is any question regarding the
cleanliness of the fluid, do not use it. Containers for hydraulic fluid must never
be left open to air longer than necessary.
Brake Oil level check procedure
1. Remove pilot seats
2. Check oil reservoir for oil level (Refer to Figure 12.)
3. If necessary, remove reservoir filler cap and replenish oil
4. Refit reservoir filler cap
5. Reinstall pilot seats
