- Inconsistent power output
Knowing when to replace your brushes and understanding how to undertake the process can dramatically improve your tool’s performance.

Steps to Replace the DeWalt 389025-04 Brush Kit
Now that we’re all set, let’s walk through the step-by-step process necessary to replace the brush kit. This practical guide will help ensure a successful replacement.
Step 1: Disconnect Power Supply
For your safety, always start by disconnecting the power supply to your tool. If it’s a corded tool, unplug it. For cordless models, remove the battery pack before proceeding.
Step 2: Access the Brush Housing
Most DeWalt tools have a specific casing that protects the brushes. Using the screwdriver, carefully unscrew the casing or access panel to locate the brush housing.
Tips for Accessing the Brush Housing
- Be gentle while prying the casing apart to avoid any breakage.
- Keep all screws in a designated area so you can easily reinstall them later.
Step 3: Remove the Old Brush
Once you have access to the brush housing, you will see the brushes clearly. Carefully remove the old brush by pulling it out from its slot. Take note of how it is positioned, as the new brush will need to be installed in the same orientation.
Inspecting the Old Brush
While removing the old brush, examine it for any signs of wear or damage. If the brush is cracked or significantly worn down, it’s a clear indication that it needs replacement, which reinforces the importance of regular maintenance.
Step 4: Insert the New Brush
Prepare the new DeWalt 389025-04 brush for installation. Insert it into the housing in the same direction as the old brush. Ensure it fits snugly in place and is secured correctly within the slots.
Step 5: Reassemble the Tool
Once the new brushes are in place, it’s time to reassemble your tool. Replace the brush housing cover carefully, lining it up with any screw inserts. Use your screwdriver to secure all screws tightly, ensuring that there are no loose parts.
Step 6: Reconnect Power and Test
After you have completely reassembled the tool, reconnect the power supply. If you’re using a battery-operated model, slide the battery pack back into place. Turn on your tool to test its functionality. Ideally, you should immediately notice improved performance with the new brush kit.
Maintenance Tips for Longevity
To prolong the life of your new brushes and keep your DeWalt tools in tip-top condition, consider the following maintenance tips:
Regular Cleaning
Debris and dust can accumulate in the brush area over time. Regular cleaning can prevent buildup, improving brush performance and longevity.
Monitor Performance
Be attentive to changes in your tool’s performance. If you notice any signs of decreased power or erratic functionality, it might be time for another brush inspection.
Use Appropriate Tools
Always utilize compatible and certified DeWalt accessories and brushes. This ensures your tools operate safely and efficiently, minimizing wear and tear.

What tools do I need to replace the DeWalt 389025-04 Brush Kit?
Replacing the DeWalt 389025-04 Brush Kit requires some basic tools that are typically found in a home workshop. At a minimum, you’ll need a screwdriver set, preferably both Phillips and flathead, to access the brush holder. Additionally, having a pair of pliers can be helpful when removing or attaching any wires. A clean workbench or surface to lay out your tools and parts will also make the process smoother.
It’s also advisable to have safety gear on hand, such as eye protection and gloves, to safeguard yourself during the replacement process. Having a soft cloth or brush to clean the motor area might help enhance the longevity of your tool and ensure that it operates efficiently after the replacement.
How do I know when it’s time to replace the brush kit?
Indicators that it’s time to replace the brush kit include reduced power, unusual noises, or excessive sparking around the motor. If you notice that your DeWalt tool isn’t functioning at full capacity or has a significant decrease in performance, those are strong signs that replacement is warranted. Additionally, visually inspecting the brushes can provide insights; if they appear worn down or have a distinct burn mark, it’s time for a change.
Regular maintenance is key to keeping your tools in optimal working condition. If you frequently use your tools, it’s worth considering a preventive replacement on a scheduled basis rather than waiting for them to show issues. Checking brushes periodically can prolong the life of your tool and enhance its performance.
Can I replace the brush kit without professional help?
Yes, replacing the brush kit on your DeWalt tool can be a DIY task if you’re comfortable working with power tools. With the right tools and a bit of patience, you can successfully handle this type of repair on your own. Many users have successfully replaced their brush kits by following the manufacturer guidelines and watching instructional videos available online.
However, if you’re unsure or uncomfortable performing the replacement, seeking help from a professional is always a good option. Professional technicians have experience with various tools and can ensure that the job is done safely and effectively. It’s essential to prioritize safety and accuracy when working with electric tools.
Is there a difference between original and aftermarket brush kits?
Yes, there is a notable difference between original (OEM) and aftermarket brush kits. OEM brush kits are made by DeWalt and are designed specifically for their tools, ensuring a perfect fit and compatible performance. Using OEM parts often leads to better tool longevity and reliability, as they are manufactured to meet the original specifications.
On the other hand, aftermarket brush kits can vary in quality. While some may be effective and less expensive, others might not meet the necessary performance standards and could potentially cause damage to your tool. It’s essential to research and select reputable aftermarket products if you choose this route, ensuring they match or exceed the quality of OEM parts.
What are the steps to replace the brush kit?
Replacing the brush kit involves several structured steps to ensure a successful installation. First, disconnect your tool from the power source and remove any battery packs if applicable. Next, access the brush holder by removing the screws that secure the motor housing. This will require careful handling to avoid damaging any components during disassembly.
Once you’ve exposed the brush assembly, carefully remove the old brushes by detaching the clips or screws holding them in place. Replace them with the new brushes, ensuring they fit snugly and securely. After reassembling the tool, perform a quick inspection to ensure everything is fitted correctly, then reconnect the power source to test the functionality.
Will replacing the brush kit void my warranty?
Replacing the brush kit yourself may indeed void the warranty, particularly if the tool shows signs of damage due to improper installation. Manufacturers typically specify that any unauthorized repairs or modifications can void warranties, so it’s crucial to check the terms and conditions. If your tool is still under warranty, you may consider reaching out to DeWalt’s customer service for guidance on authorized service options.
If you decide to proceed with the replacement, keep in mind that using authentic DeWalt parts and following proper procedures can help mitigate warranty issues. Documenting the replacement process and retaining receipts for parts can also provide evidence of your work if any disputes arise regarding warranty coverage.
How can I maintain my tool after replacing the brush kit?
After replacing the brush kit, maintaining your tool will require regular cleaning and occasional lubrication. Dirt and debris can accumulate inside the motor, so it’s essential to clean the housing and brush area periodically. Use a soft brush or compressed air to remove any build-up, which will help your tool run more efficiently and minimize wear on the new brushes.
Additionally, consider inspecting the brushes every few months to assess their condition. If you are in a heavy-use scenario, maintaining an extra set of brushes on hand is a good precaution. Regular maintenance will not only extend the life of the brushes but will also enhance overall tool performance and reliability.
