Information:
Loss of the Front Service Brakes
Possible Causes
There is a malfunction of the brake system.
Perform general troubleshooting tests and visual checks.
The spool in the service brake control valve is sticking.
Check for a sticking valve spool. Refer to Testing and Adjusting, "Brake Line Pressure for Front Drive Axle - Test".
Low oil pressure from the piston pump.
Perform a pressure test on the piston pump. Refer to Testing and Adjusting, "Pressure for Piston Pump (Brake, Ejector, Fan) - Test".Loss of the Service Brakes on the Trailer
Possible Causes
There has been a malfunction of the brake system.
Perform general troubleshooting tests and visual checks.
The service brake spool for the service brakes on the trailer in the service brake control valve is sticking.
Check for a sticking valve spool. Refer to Testing and Adjusting, "Brake Line Pressure for Center and Rear Drive Axle - Test".
There is low system pressure from the piston pump.
Perform a pressure test for the piston pump. Refer to Testing and Adjusting, "Pressure for the Piston Pump (Brake, Ejector, Fan) - Test". Inefficient Service Brakes
Possible Causes
There are worn service brake pads on the front, the center or the rear axle.
Check the brake pads. Renew worn brake pads. Refer to Operation and Maintenance Manual, "Brake Pads - Check".
There is air in the brake system oil.
Perform general troubleshooting tests and visual checks.
Bleed the service brakes. Refer to Testing and Adjusting, "Service Brake Air - Purge".
There is brake oil leakage.
Perform general troubleshooting tests and visual checks.
There is low accumulator precharge pressure.
Check the accumulator precharge pressure with the accumulators on the machine. Check the accumulators for the front service brakes and the service brakes on the trailer. Refer to Testing and Adjusting, "Brake Accumulator Service - Test and Charge".
An accumulator is damaged.
Perform a precharge test for the accumulator for the problem circuit. Refer to Testing and Adjusting, "Brake Accumulator Service - Test and Charge".
The service brake control valve is damaged.
Check for a sticking valve spool. Refer to Testing and Adjusting, "Brake Line Pressure for Front Drive Axle - Test".The Parking Brake Cannot be Disengaged
Possible Causes
The parking brake solenoid valve on the parking brake control valve has an open circuit or there is a bad electrical connection.
Test the parking brake solenoid valve on the parking brake control valve. Refer to Testing and Adjusting, " Solenoid Valve (Parking Brake) - Test".
There is a malfunction of the parking brake system.
Perform general troubleshooting tests and visual checks.
There is internal leakage to the tank from one of the following components: piston pump, parking brake control valve, service brake control valve and the check and pressure reducing valve.
Check the flow of the oil in the lines to the tank. Excessive flow could indicate that the components are leaking internally.
There is low accumulator precharge pressure.
Check the precharge pressure of the parking brake accumulator with the accumulator on the machine. Refer to Testing and Adjusting, "Brake Accumulator (Parking) - Test and Charge".
