Left front wheel brake assembly
(1) Pressure tap
Connect Tooling (B) to pressure tap (1) on the wheel brake assembly.
Start the engine. Refer to Table 1 for temperature of the oil when performing this procedure.
Run the engine at low idle. Refer to Table 1 for the minimum pressure.
Run the engine at high idle. Refer to Table 1 for the maximum pressure. Note: If this pressure is exceeded, seal damage will result.
If the low idle and high idle pressures are incorrect, check the relief valve (brake oil cooler) pressure setting. Reference: Refer Testing and Adjusting, "Relief Valve (Brake Oil Cooler) - Test and Adjust".
If necessary, repeat Step 1 through Step 4.
