Gehl DL-6H skid steer owners have reported various issues related to the wet brake system, which is crucial for controlling and stopping the machine. Wet brakes are typically used in heavy equipment to provide smoother, more efficient braking. However, problems can arise over time, leading to reduced performance and potential safety concerns. In this article, we’ll examine the common issues with the wet brake system on the Gehl DL-6H and provide guidance on how to address these problems.
Understanding the Wet Brake System
Wet brakes work by using oil to lubricate the brake components, which helps dissipate heat and prevent wear. These brakes are typically more durable than dry brakes and can handle heavier loads, which is why they are commonly used in skid steers and other heavy equipment.
However, the system can experience problems, especially if the fluid becomes contaminated, or the brake components start to wear out. Since wet brakes are integral to the safe operation of the equipment, it is essential to understand the issues that can arise.
Common Wet Brake Issues on Gehl DL-6H
The wet brake system on the Gehl DL-6H is designed to provide smooth and efficient braking for tough work environments. However, like any complex system, it can encounter issues such as brake dragging, fluid contamination, or worn components. Regular maintenance and attention to the brake system are key to ensuring the continued safe and efficient operation of the machine. If you're experiencing issues, addressing them promptly can prevent further damage and ensure the longevity of your Gehl DL-6H skid steer.

Common Wet Brake Issues on Gehl DL-6H
- Brake Dragging or Reduced Performance
One of the most common issues with wet brakes is dragging or poor braking performance. This can be caused by several factors, including contaminated brake fluid, worn brake components, or incorrect adjustment. If the brake system does not disengage fully when the operator releases the brake pedal, it can lead to continuous friction, causing the brakes to overheat and lose efficiency.
- Contaminated Brake Fluid
If the brake fluid is not changed regularly or if the machine operates in harsh conditions (such as wet or dusty environments), contaminants can enter the fluid. This can cause the fluid to lose its lubricating and cooling properties, leading to poor brake performance and even damage to the brake components. Checking and replacing the brake fluid at regular intervals is essential to maintaining brake system efficiency.
- Air in the Brake System
Air in the hydraulic lines or brake system can lead to spongy or unresponsive brakes. This typically occurs if there is a leak in the system or if the brake fluid was not properly bled during maintenance. If the brake pedal feels soft or unresponsive, it is a sign that air may have entered the system and needs to be purged.
- Worn Brake Discs or Pads
Just like any other braking system, the components of the wet brake system, such as brake discs or pads, can wear out over time. When these components become excessively worn, the braking performance will significantly decrease. Regular inspection of the brake discs and pads is necessary to ensure they remain in good condition.
- Hydraulic Pressure Issues
Wet brakes rely on hydraulic pressure to function properly. If there is an issue with the hydraulic system, such as a low fluid level or a failing pump, the brakes may not engage or disengage correctly. This can lead to uneven braking or complete failure of the braking system.
- Inspect the Brake Fluid
Start by checking the brake fluid level and inspecting its condition. If the fluid appears dark, contaminated, or low, it should be replaced. Be sure to use the correct type of brake fluid specified by Gehl for the DL-6H model.
- Check for Leaks
Inspect the hydraulic system for any visible leaks. Leaks can lead to air entering the brake lines, resulting in poor braking performance. Tighten any loose fittings or replace any damaged seals to prevent further leakage.
- Bleed the Brake System
If you suspect air is trapped in the brake system, you will need to bleed the brakes to remove the air. This can be done by following the manufacturer’s guidelines for bleeding the hydraulic system. It may require a special tool to apply the proper pressure.
- Inspect Brake Components
Check the brake discs and pads for signs of wear. If they are worn down beyond the manufacturer's specifications, they should be replaced. Additionally, inspect the hydraulic lines and valves to ensure there are no blockages or damage that could hinder brake performance.
- Check Hydraulic Pressure
If the problem appears to be related to insufficient hydraulic pressure, test the hydraulic pump and system pressure. Low hydraulic pressure can cause the brakes to fail to engage properly. If the pressure is low, there may be a need for repairs to the hydraulic pump, filters, or hoses.
- Regular Maintenance
Regular maintenance of the brake system is crucial to ensuring long-term performance. This includes changing the brake fluid, inspecting components, and ensuring that there are no leaks in the system. Following the maintenance intervals recommended by Gehl will help avoid unnecessary wear and tear.
- Use the Right Fluids
Always use the manufacturer-recommended brake fluid to ensure the brake system operates efficiently. Using the wrong type of fluid or poor-quality fluid can damage the system and cause premature wear.
- Monitor Operating Conditions
Operating in extreme conditions, such as excessive heat, wet environments, or dusty conditions, can lead to faster wear on the brake system. Whenever possible, try to minimize exposure to these conditions or perform more frequent maintenance checks.
- Train Operators
Ensure that operators are properly trained in the use and maintenance of the equipment, especially regarding brake systems. Encouraging operators to report any issues with braking immediately can help catch problems early before they cause significant damage.
