The CAT 955H is a well-regarded piece of heavy equipment used primarily for construction and material handling tasks. One of the critical components of this machine is its braking system, which ensures safe and efficient operation. Over time, the brake bands in the 955H can wear out, requiring replacement. If left unaddressed, this can lead to decreased braking performance, posing safety risks. In this guide, we will cover the process of replacing the brake bands on the CAT 955H, along with some important considerations and tips.
Why Brake Band Replacement is Necessary
Brake bands in the CAT 955H, like in other heavy equipment, experience significant wear and tear due to constant friction and pressure. If the brake bands become too worn, the braking efficiency of the machine will decrease. This can lead to longer stopping distances and reduced control, especially when the machine is working on uneven terrain or carrying heavy loads.
Signs that your brake bands may need replacing include:
Tools and Materials Needed
Before you begin the brake band replacement process, make sure you have the following tools and materials:
Replacing the brake bands on a CAT 955H is an essential maintenance task that ensures the machine operates safely and efficiently. While the process requires careful attention to detail and the proper tools, following the step-by-step guide can help you replace the brake bands correctly. By maintaining your braking system with regular checks and timely replacements, you can extend the life of your CAT 955H and avoid costly repairs in the future. Always prioritize safety during the repair process, and don't hesitate to consult a professional if you're unsure about any aspect of the replacement.

If the brake bands become too worn, the braking efficiency of the machine will decrease. This can lead to longer stopping distances and reduced control, especially when the machine is working on uneven terrain or carrying heavy loads.
Signs that your brake bands may need replacing include:
- Reduced braking power
- Unusual noises when applying the brakes (e.g., grinding or squealing)
- The brake pedal feels spongy or unresponsive
- Difficulty in holding the machine on a slope
Tools and Materials Needed
Before you begin the brake band replacement process, make sure you have the following tools and materials:
- Wrenches and Socket Set: To remove bolts and fasteners.
- Hydraulic Jack or Lifting Equipment: To lift the machine safely and remove the wheels if necessary.
- Brake Band Replacement Kit: Make sure you have the correct replacement bands for your CAT 955H model.
- Safety Gear: Gloves, safety glasses, and steel-toed boots are essential for protection.
- Brake Cleaner: To clean the brake components and surrounding areas before installing new parts.
- Torque Wrench: To ensure the correct tightness of bolts during reassembly.
- Prepare the Machine for Maintenance:
- Park on a Level Surface: Ensure the machine is on a flat surface to avoid it from rolling during the repair process.
- Engage the Parking Brake: Even though the brake bands are being replaced, engaging the parking brake adds an extra layer of safety.
- Lift the Machine: Using a hydraulic jack or lifting equipment, raise the machine so that the wheels can be removed if necessary.
- Park on a Level Surface: Ensure the machine is on a flat surface to avoid it from rolling during the repair process.
- Remove the Wheels (if required):
- If you need to access the brake bands from the wheels, remove them by loosening the lug nuts and carefully pulling the wheels off. Ensure the machine is properly supported before removing the wheels to avoid accidents.

- Locate the Brake Band Housing:
- The brake bands on the CAT 955H are housed in the brake drum assembly. Depending on the model, you may need to remove covers or shields to gain access to the brake drum.
- Remove any Obstructions: If there are components blocking access to the brake bands, such as a protective cover or drive shaft, carefully remove these parts. Make a note of how the components are arranged to facilitate reassembly.

- Remove the Worn Brake Bands:
- Once you have clear access to the brake bands, use a wrench or socket to loosen and remove the bolts or fasteners securing the brake bands in place. Be sure to keep track of any washers or small components that may come loose.
- Carefully remove the worn brake bands from the housing. Inspect the condition of the old bands for any additional signs of wear, such as cracks, excessive heat discoloration, or damage.
- Once you have clear access to the brake bands, use a wrench or socket to loosen and remove the bolts or fasteners securing the brake bands in place. Be sure to keep track of any washers or small components that may come loose.
- Clean the Brake Components:
- Before installing the new brake bands, thoroughly clean the brake drum and other components using brake cleaner. This will remove any debris, dust, or old grease that could affect the performance of the new bands.
- Inspect the brake drum for any significant damage or wear. If the drum is excessively worn or scored, it may need to be resurfaced or replaced.
- Before installing the new brake bands, thoroughly clean the brake drum and other components using brake cleaner. This will remove any debris, dust, or old grease that could affect the performance of the new bands.
- Install the New Brake Bands:
- Take the new brake bands and carefully install them into the brake drum assembly. Ensure the bands are properly aligned and seated in the correct position.
- Secure the bands with the appropriate bolts or fasteners. Use a torque wrench to tighten the bolts to the manufacturer’s specified torque value to avoid over-tightening or under-tightening.
- Take the new brake bands and carefully install them into the brake drum assembly. Ensure the bands are properly aligned and seated in the correct position.
- Reassemble the Components:
- If you removed any additional parts, such as the drive shaft or protective cover, reassemble them in reverse order of removal.
- Reinstall the wheels if they were removed earlier. Tighten the lug nuts securely.
- If you removed any additional parts, such as the drive shaft or protective cover, reassemble them in reverse order of removal.
- Test the Brakes:
- Lower the machine back to the ground carefully, ensuring it is stable.
- Start the engine and test the brake system by applying the brakes gently. Check for proper braking performance, including smooth engagement and a firm pedal feel.
- Test the braking power by gently driving the machine forward and applying the brakes. If the braking response is sluggish or inconsistent, recheck the installation of the brake bands and components.
- Lower the machine back to the ground carefully, ensuring it is stable.
- Check for Leaks and Issues:
- Inspect the brake system for any signs of fluid leaks, unusual noises, or components that may be loose. If everything is functioning properly, you’ve successfully completed the brake band replacement.
- Inspect the brake system for any signs of fluid leaks, unusual noises, or components that may be loose. If everything is functioning properly, you’ve successfully completed the brake band replacement.
- Regular Inspection: Even after replacing the brake bands, regular inspections are key to identifying any wear or damage before it leads to further issues.
- Use Genuine Parts: Always use genuine CAT parts or OEM (Original Equipment Manufacturer) parts for replacements to ensure compatibility and quality.
- Avoid Overloading: Avoid overloading the machine, as it can cause the brake bands to wear out more quickly.
- Brake Fluid Levels: Ensure the brake fluid is topped off and in good condition, as low or dirty fluid can affect braking performance.
