DeWalt is known for its powerful and reliable power tools, and their circular saws are no exception. However, like any tool, they can experience issues over time. One common problem that users may encounter with their DeWalt circular saw is the brake not working properly. This can be frustrating and even dangerous if left unresolved.
But before you rush to bring your circular saw to a repair shop, there are some simple fixes that you can try at home. In this guide, we’ll discuss 7 potential solutions for a Dewalt circular saw brake not working.
Diagnosing the Issue
Before you attempt to fix your saw’s brake, it’s important to understand what might be causing the problem. If you’ve pressed the brake and it doesn’t stop the saw blade efficiently or at all, issues could be as simple as a dirty contact or as complex as a faulty part.
The first step is to disengage the power source completely from the saw (either by unplugging it or removing the battery) and giving the tool a good visual inspection.
Signs of a Faulty Brake
- Saw blade doesn’t stop immediately upon release of the trigger
- You can hear the brake system engaging, but the blade doesn’t stop
- Stopping time is slower than usual
- The blade doesn’t stop at all, and you need to wait for the blade to wind down naturally
How to Fix Dewalt Circular Saw Brake Not Working
Check the Blade
The first thing you should do when experiencing issues with your DeWalt circular saw is to check the blade.
Over time, the blade can become dull or damaged, causing it to not cut properly and putting strain on the brake. If this is the case, simply replacing the blade should fix the issue.
Clean the Brake Components
As mentioned, sometimes the issue is as simple as dirt and debris accumulated on the brake components. To clean them:
- Remove the blade guard and blade from the saw
- Use a clean cloth or brush to wipe down the brake components (located near the motor)
- Pay special attention to the contacts between the brake pads and armature
- Reinstall the blade and blade guard and test the brake function
Adjust the Brake Contact Arm
If cleaning didn’t solve the issue, it’s possible that the brake contact arm (a small metal piece) may have shifted out of alignment. To adjust it:
- Remove the blade guard and blade from the saw
- Use a screwdriver to loosen the screw holding the brake contact arm in place
- Align the arm with the brake pads and retighten the screw
- Reinstall the blade and blade guard and test the brake function
Replace Brake Pads
If cleaning and adjusting didn’t work, it’s likely that your brake pads have worn out and need to be replaced. You can purchase replacement brake pads from a Dewalt dealer or online.
To replace the brake pads:
- Remove the blade guard and blade from the saw
- Use a screwdriver to remove the brake pad screws and pull out the old pads
- Install the new pads, making sure they are aligned with the armature
- Reinstall the blade and blade guard and test the brake function
Adjust the Tension on the Brake Spring
If the brake pads are new but the brake still isn’t functioning properly, it could be due to a loose or tight brake spring. To adjust it:
- Remove the blade guard and blade from the saw
- Use pliers to loosen or tighten the tension on the brake spring (located near the motor)
- Reinstall the blade and blade guard and test the brake function
Lack Of Lubrication
Over time, the brake mechanism can become stiff due to lack of lubrication. To fix this:
- Remove the blade guard and blade from the saw
- Use a lubricant specifically designed for power tools and apply it to all moving parts of the brake mechanism
- Reinstall the blade and blade guard and test the brake function
Battery or Power Source Issues
If none of the above solutions work, it’s possible that the issue lies with your battery or power source. Here are some things to try:
- If using a battery-powered saw, make sure the battery is fully charged and in good condition
- If using a corded saw, try plugging it into different outlets and check if there are any issues with the power source
Seek Professional Assistance
If none of these solutions work, it’s best to take your saw to a professional for further diagnosis and repair.
Attempting any complicated repairs on your own can be dangerous and may cause more harm than good. It is always better to err on the side of caution when it comes to power tool maintenance.
