Introduction
The John Deere 310 SG backhoe loader is widely used for various construction and excavation tasks. One common concern that operators encounter with this model is related to the parking brake mechanism and its operation. This summary highlights a typical situation, possible causes, and steps taken to resolve the issue.
Issue with the Parking Brake
An owner of a John Deere 310 SG experienced a problem where the parking brake did not function properly. The brake would either fail to engage fully or not hold the machine in place, especially on inclined surfaces. This raised safety concerns and made routine operation more challenging.
Initial Checks
The first step was to inspect the parking brake lever and linkage. Operators often find that loose or misadjusted linkages can prevent the brake from engaging correctly. In this case, the linkage appeared intact but did not provide enough tension to hold the brake.
Possible Causes
To fix the issue, the operator performed the following steps:
To avoid similar issues, operators were reminded to:
The John Deere 310 SG parking brake is a simple but essential system that ensures the machine stays stationary when required. Regular inspection, timely adjustment, and replacement of worn parts are key to keeping the brake in good working order and ensuring safe operation on the job site.

Initial Checks
The first step was to inspect the parking brake lever and linkage. Operators often find that loose or misadjusted linkages can prevent the brake from engaging correctly. In this case, the linkage appeared intact but did not provide enough tension to hold the brake.
Possible Causes
- Worn Brake Pads: Over time, the parking brake pads wear out and lose their grip, which can reduce braking efficiency.
- Stretched or Damaged Cable: The cable that connects the lever to the brake assembly can stretch or fray, causing slack and reduced tension.
- Hydraulic Issues: Since some parking brake systems are hydraulically assisted, a malfunction in the hydraulic circuit could lead to improper brake engagement.
- Adjustment Needed: Sometimes, the brake simply needs to be adjusted to compensate for wear and maintain proper operation.
To fix the issue, the operator performed the following steps:
- Checked the Cable Tension: Inspected the entire length of the cable for wear or damage and adjusted the tension to ensure it pulled the brake arm fully.
- Inspected Brake Components: Removed the brake assembly to inspect pads and components for excessive wear or contamination.
- Replaced Worn Parts: In cases where the pads were worn out, new ones were installed.
- Tested the Brake: After adjustments and replacements, the brake was tested multiple times on various slopes to confirm it would hold the machine securely.
To avoid similar issues, operators were reminded to:
- Perform routine checks on the parking brake mechanism.
- Lubricate linkages and cables regularly.
- Adjust the brake system when needed.
- Replace worn components promptly to maintain safety.
