Strong Industries Brake Issues and Solutions

[MikePhua]

Strong Industries is a well-known manufacturer specializing in the design and production of heavy-duty material handling equipment, particularly for the construction and industrial sectors. Their range of products, including trailers and lifts, is widely used for lifting, transporting, and stabilizing heavy loads. As with all industrial machinery, proper maintenance and troubleshooting of key systems such as the braking system are essential for ensuring safe and efficient operation. Brake issues are among the most common problems faced by operators of Strong Industries' equipment, and addressing these problems promptly is crucial for safety.
Understanding Strong Industries' Brake Systems
Strong Industries typically uses hydraulic and air-operated braking systems in their equipment, which are designed to provide high stopping power and reliability under heavy load conditions. These braking systems use hydraulic fluid or compressed air to generate the force required to stop the wheels or the entire vehicle, depending on the application.
Brake components generally include:

1. Brake Pads and Shoes: These are the friction elements that press against the brake rotor or drum to create the stopping force.
   
2. Brake Rotors and Drums: The surfaces that the brake pads or shoes press against to slow or stop the equipment.
   
3. Brake Fluid or Air Lines: These carry hydraulic fluid or air to the brake mechanism.
   
4. Brake Calipers or Cylinders: These house the mechanisms that press the brake pads or shoes against the rotors or drums.
   

Each of these components plays a crucial role in the overall performance of the braking system, and failure in any one of them can lead to reduced braking power or complete brake failure.
Common Brake Issues with Strong Industries Equipment

1. Brake Fade: Brake fade occurs when the brakes lose their stopping power, usually due to excessive heat buildup. This can happen when the equipment is used heavily for extended periods, such as in construction or mining operations. When the brake components overheat, the friction material on the brake pads or shoes begins to lose its effectiveness, resulting in reduced braking performance.
   
2. Uneven Brake Wear: Uneven wear on brake pads or shoes can be a sign of improper alignment or issues with the hydraulic or air pressure system. If one side of the brake system is applying more pressure than the other, the pads or shoes will wear unevenly, leading to poor braking performance and potentially more severe damage.
   
3. Leaking Brake Fluid or Air: Leaks in the brake system can lead to a loss of hydraulic pressure or air pressure, rendering the brakes ineffective. Common causes of leaks include worn-out seals, cracked lines, or loose fittings. A brake fluid leak can also cause the fluid levels to drop, further reducing the braking power.
   
4. Soft or Spongy Pedal: A soft or spongy brake pedal is a common sign of air or fluid in the brake lines. This issue can arise from air entering the hydraulic system (for hydraulic brakes) or from moisture or contaminants in the brake fluid. It can also occur if there’s a leak in the system that causes the brake pressure to drop.
   
5. Brake Drag: Brake drag occurs when the brakes do not fully release after being applied. This can cause excessive wear on the brake pads or shoes, as well as overheating. Brake drag may result from stuck calipers or cylinders, improper adjustments, or faulty return springs.
   

Troubleshooting Brake Problems
When facing brake issues on Strong Industries equipment, it’s essential to perform a thorough inspection and follow a structured troubleshooting process. Here's a step-by-step guide to help diagnose and resolve common brake issues:

1. Check Brake Fluid Levels: For hydraulic braking systems, check the brake fluid levels. Low fluid levels could indicate a leak or that the fluid needs to be replaced. Ensure that the fluid used is the manufacturer-recommended type to avoid compatibility issues.
   
2. Inspect for Leaks: Visually inspect all brake lines, hoses, fittings, and seals for signs of leaks. Pay close attention to areas where hydraulic or air lines connect to the brake calipers or master cylinder. Tighten any loose fittings and replace worn seals to prevent further leakage.
   
3. Examine Brake Pads or Shoes: Inspect the condition of the brake pads or shoes. If they are worn down unevenly, it could indicate an alignment issue or problems with the brake calipers. Replace any worn-out pads or shoes to maintain optimal braking power.
   
4. Bleed the Brakes: If the brake pedal feels soft or spongy, air may have entered the hydraulic or air lines. Bleeding the brakes will remove air from the system and restore normal brake function. For air brakes, ensure that there is no moisture in the lines, as this can lead to rust and blockages.
   
5. Check for Overheating: If brake fade is an issue, inspect the brake rotors or drums for signs of heat damage. In some cases, replacing the rotors or drums is necessary. Also, ensure that the equipment is not being overused, as constant heavy braking can cause overheating.
   
6. Test Brake Release Mechanism: For brake drag, check the calipers, cylinders, and return springs to ensure that the brake components are fully releasing after application. Sticking calipers or faulty return springs can cause the brakes to remain partially engaged, leading to excessive wear.
   

Preventive Maintenance for Strong Industries’ Brake Systems
To prevent brake issues from recurring, a regular maintenance schedule should be followed. Key preventive maintenance tasks include:

1. Regular Fluid Changes: Change brake fluid regularly to ensure that the system operates at optimal efficiency. Contaminated or old brake fluid can lead to corrosion and reduced braking power.
   
2. Routine Inspections: Perform thorough inspections of the brake system every few months. Check for wear, leaks, and any signs of damage to key components. This will help identify potential issues before they cause major problems.
   
3. Brake Pad and Shoe Replacement: Depending on usage, brake pads and shoes should be replaced periodically. Over time, these components will naturally wear out and lose their effectiveness.
   
4. Brake Line Flushing: Flush the brake lines periodically to remove contaminants that could compromise braking performance. This is especially important for hydraulic systems where debris and moisture can cause damage to seals and valves.
   
5. Caliper and Cylinder Maintenance: Clean and lubricate the brake calipers and cylinders regularly to prevent sticking or uneven pressure distribution.
   

Conclusion
Brake issues on Strong Industries equipment, such as hydraulic and air-operated braking systems, are common but can be mitigated through proper maintenance and timely troubleshooting. Addressing problems like brake fade, uneven wear, leaks, or soft pedals requires a thorough inspection and understanding of the braking system. Regular maintenance and adherence to manufacturer recommendations are crucial for preventing brake system failures, ensuring the longevity of the equipment, and maintaining safety on the job site. By staying proactive and addressing minor issues early, operators can significantly reduce the risk of costly repairs and downtime.
