Powered by a 4-cylinder diesel engine, the 310D offers a balance of power and efficiency. Its hydraulics system allows for precise digging and lifting, while the extended reach of the front loader and digging depth of the backhoe provide enhanced productivity.
Despite its solid engineering, the 310D is not immune to the wear and tear that comes with prolonged use. As a heavy-duty machine, issues such as sticking brakes can arise from a variety of causes, often requiring careful diagnosis and timely maintenance.
Common Causes of Sticking Brakes
Brake sticking occurs when the brake system fails to release completely after being engaged. This can result in the machine dragging, overheating, or losing efficiency in movement. Several factors can contribute to brake sticking on the John Deere 310D:
The most apparent sign of sticking brakes is when the machine feels sluggish or drags while moving. However, several other signs can indicate brake issues on the John Deere 310D:
When troubleshooting sticking brakes on the John Deere 310D, the following steps can help identify the cause:
Once the underlying issue has been identified, the appropriate solution can be implemented:
Sticking brakes on the 1993 John Deere 310D can be caused by a range of issues, from contaminated brake fluid to worn components. Identifying and addressing the root cause promptly is essential for restoring the machine's performance and preventing further damage. By regularly inspecting and maintaining the brake system, operators can ensure that the John Deere 310D remains a reliable and safe piece of equipment for construction and excavation tasks.

Common Causes of Sticking Brakes
Brake sticking occurs when the brake system fails to release completely after being engaged. This can result in the machine dragging, overheating, or losing efficiency in movement. Several factors can contribute to brake sticking on the John Deere 310D:
- Contaminated Brake Fluid: The brake system on the 310D relies on hydraulic fluid to operate the brakes. If the brake fluid becomes contaminated with dirt, moisture, or debris, it can affect the performance of the brake components. This can lead to sticky or sluggish brakes as the hydraulic fluid loses its ability to properly activate the brake system.
- Worn or Damaged Brake Components: Over time, components such as the brake pads, discs, and calipers can wear out. Worn brake pads can cause uneven friction, which might cause the brake to stick in the engaged position. Similarly, damaged calipers or seals can cause the brake to remain engaged, leading to dragging or overheating.
- Faulty Brake Master Cylinder: The master cylinder is responsible for generating hydraulic pressure in the brake system. If the master cylinder becomes faulty or develops a leak, it can cause the brakes to stick. A malfunctioning master cylinder might not properly release the brake pressure, leading to excessive brake engagement.
- Brake Line Blockages or Leaks: Brake lines carry hydraulic fluid to the brake system. Blockages in the lines or leaks can disrupt the flow of fluid, causing pressure imbalances and leading to brake sticking. This can happen due to corrosion, wear, or damage to the brake lines, particularly in older machines.
- Incorrect Brake Adjustment: Over time, the brake system on the 310D may require adjustment to ensure proper operation. If the brakes are adjusted too tight, they may not fully release when the brake pedal is released, leading to a sticking sensation or dragging.
- Damaged or Sticking Brake Drums: The brake drums or rotors are integral to the braking system. If these components are damaged or have worn unevenly, they may not allow the brakes to release properly, causing the brakes to stick. This is particularly common if the vehicle is used in heavy, high-stress conditions.
The most apparent sign of sticking brakes is when the machine feels sluggish or drags while moving. However, several other signs can indicate brake issues on the John Deere 310D:
- Uneven Movement: When driving the backhoe, you may notice that it moves more slowly or with uneven resistance. This could be due to the brakes not fully releasing, causing friction on the wheels or tracks.
- Overheating: If the brakes are dragging, they can become overheated, leading to burning smells or excessive heat buildup on the wheels or drums. This can also cause the brake pads and other components to wear out prematurely.
- Increased Fuel Consumption: When the brakes are sticking, the machine is forced to work harder to move, leading to an increase in fuel consumption. This is because the engine must overcome the resistance caused by the brake drag.
- Unusual Noise: Another sign of sticking brakes is a grinding or squealing noise coming from the brake components. This may be due to worn-out brake pads or discs or foreign debris caught in the brake system.
- Erratic Pedal Feel: If the brake pedal feels "spongy," hard to press, or unusually sensitive, it could be a sign that the brake fluid is not functioning correctly, possibly due to contamination or air in the system.
When troubleshooting sticking brakes on the John Deere 310D, the following steps can help identify the cause:
- Check Brake Fluid: Start by inspecting the brake fluid reservoir. Ensure that the fluid is clean and at the proper level. If the fluid is dirty, contaminated, or low, flush and replace it with the appropriate type of hydraulic fluid as specified in the manual. A hydraulic fluid flush will remove contaminants and restore proper brake function.
- Inspect Brake Components: Examine the brake pads, calipers, discs, and rotors for signs of wear or damage. If the pads are excessively worn or if there are grooves or scoring on the discs, they should be replaced. Pay attention to the condition of the brake seals and caliper pistons, as these can become damaged or corroded over time.
- Check Brake Lines: Inspect the brake lines for signs of leaks or blockages. If there is a visible leak, the damaged section of the brake line must be replaced. If the lines are clogged, flush them to remove any obstructions.
- Test the Master Cylinder: The master cylinder is critical to the proper functioning of the brake system. If you suspect a malfunction, check for leaks around the master cylinder and test its pressure output. A faulty master cylinder will need to be rebuilt or replaced.
- Adjust the Brakes: If the brakes are misadjusted, they may remain engaged even when the pedal is released. Use the machine’s manual to adjust the brake system to the manufacturer’s specifications.
- Inspect for Brake Drum or Rotor Damage: Check the brake drums or rotors for damage, cracks, or uneven wear. If these components are worn out or damaged, replace them as needed to ensure smooth braking action.
Once the underlying issue has been identified, the appropriate solution can be implemented:
- Brake Fluid Replacement: Flush the brake system and replace the old fluid with fresh hydraulic fluid. Ensure that no contaminants are present in the fluid lines.
- Component Replacement: Replace worn or damaged brake components, including brake pads, calipers, discs, or seals. This will restore the functionality of the brake system and prevent further issues.
- Brake Line Repairs: If brake lines are leaking or blocked, repair or replace the affected sections. This will restore proper fluid pressure and prevent the brakes from sticking.
- Master Cylinder Repair: If the master cylinder is faulty, it will need to be repaired or replaced. A working master cylinder is essential for generating hydraulic pressure and ensuring that the brakes disengage properly.
- Brake Adjustment: Ensure that the brake system is correctly adjusted according to the manufacturer’s specifications. This will prevent over-tightening and ensure proper brake release.
