Troubleshooting Process:
– Check swing brake pads: Wear exceeded limits.
– Check brake hydraulic pressure: Pressure is low.
– Check brake solenoid valve: Coil resistance abnormal.
– Replaced brake pads and solenoid valve to restore function.

Root Cause: Brake pad wear and solenoid valve failure.

Required Parts: Swing brake pads, brake solenoid valve.
