Transporting a John Deere 544G loader requires careful preparation, especially when it comes to releasing the parking brake. Improper handling can lead to mechanical issues or safety hazards. This guide provides a comprehensive, step-by-step approach to safely releasing the parking brake, ensuring the loader is ready for transport.
Understanding the Parking Brake System
The John Deere 544G loader is equipped with an automatically spring-applied, hydraulically released parking brake. This system ensures the machine remains stationary when not in operation. However, when preparing to load the loader onto a trailer, it's essential to manually release the parking brake to allow movement.

Preparation Before Releasing the Parking Brake
- Ensure the Loader is on Level Ground
Position the loader on a flat surface to prevent unintended movement during the brake release process.
- Lower the Loader Bucket
Place the bucket flat on the ground. This action helps stabilize the loader and reduces the risk of tipping.
- Block the Wheels
Place wheel chocks behind the rear wheels to prevent any unintended movement once the brake is released.
- Engage the Loader's Frame Locking Bar
This safety feature secures the loader's frame, preventing any unexpected movements during maintenance.
Manually Releasing the Parking Brake
- Access the Brake Adjustment Cover
Locate the parking brake adjustment cover on the loader's frame. This cover is typically secured with three screws.
- Remove the Cover
Using a suitable screwdriver, remove the three screws and take off the cover to expose the brake adjustment mechanism.
- Loosen the Jam Nut
Identify the jam nut securing the brake adjustment screw. Using a wrench, loosen this nut to allow adjustment of the screw.
- Adjust the Brake Release Screw
Turn the brake release screw counterclockwise to release the parking brake. This action disengages the brake, allowing the loader to move.
- Retighten the Jam Nut
Once the brake is released, retighten the jam nut to secure the adjustment screw in place.
Releasing the Loader from the Trailer
- Ensure the Trailer is on Level Ground
Position the trailer on a flat surface to facilitate the safe unloading of the loader.
- Remove Wheel Chocks
Before attempting to move the loader, remove any wheel chocks to allow free movement.
- Start the Loader's Engine
Turn on the loader's engine to provide hydraulic power for movement.
- Disengage the Parking Brake
Press the parking brake switch to the "OFF" position to disengage the brake.
- Move the Loader
Slowly move the loader forward to ensure it is free from the trailer.
Troubleshooting Tips
- If the Parking Brake Won't Release
Check the hydraulic system for proper pressure. Low hydraulic pressure can prevent the brake from releasing. Inspect the brake accumulator for proper charge and look for any leaks in the system.
- If the Loader Moves After Loading
Ensure the parking brake is fully engaged and the transmission is in neutral. If the loader continues to move, inspect the brake system for any faults.
Safety Precautions
- Always Block the Wheels
Even after releasing the parking brake, always use wheel chocks to prevent unintended movement.
- Never Rely Solely on the Parking Brake
Always use wheel chocks in conjunction with the parking brake to ensure the loader remains stationary.
- Regularly Inspect the Brake System
Routine maintenance and inspections can help identify potential issues before they become serious problems.
Conclusion
Properly releasing the parking brake on a John Deere 544G loader is crucial for safe loading and unloading. By following the steps outlined in this guide and adhering to safety precautions, operators can ensure the loader is prepared for transport without compromising safety. Always consult the loader's operator manual for specific instructions and maintenance schedules.
