SERVICE BRAKES SYSTEM PRESSURE TEST - CONTINUED
N OT E
Look at pressure gage. Before you start engine, oil pressure must match pressure of hydraulic oil tank.
6.
Start engine and allow hydraulic oil to reach normal operating temperature and pressure (TM 5-3805-291-10).
7.
With assistance, hold down brake pedal and read pressure gage. Brake pressure should be 625 50 psi (4,310 345
kPa).
8.
If brake pressure is not in correct range and service brake control manifold is functioning correctly, replace service
brake control valve (WP 0116 00).
N OT E
The pressure from rear brake port should be approximately 50 psi (345 kPa) higher than pressure from
front brake port.
9.
Repeat this procedure at test port (8) to test oil pressure for front service brakes.
