Follow Manufacturer’s Recommendations

Harley-Davidson, like any other motorcycle manufacturer, provides specific recommendations for brake fluid types and specifications suitable for their bikes. It’s crucial to follow these guidelines to maintain optimal performance and ensure your safety.

Most Harley motorcycles typically use DOT 4 brake fluid. However, it’s essential to refer to your owner’s manual or contact your local dealership to be absolutely certain about the recommended brake fluid type for your specific model and year.

Remember, using the wrong brake fluid can lead to issues like decreased braking performance or damage to the braking system. Always stick to the manufacturer’s recommendations to keep your Harley running smoothly.

Flushing And Bleeding The Brake System

Regularly flushing and bleeding the brake system is crucial for maintaining optimal braking performance and removing any contaminants or moisture that might have entered the system. Here’s a step-by-step guide on how to do it:

  1. Park your Harley on a level surface and ensure it is stable.
  2. Make sure you have all the necessary tools, including a wrench, brake bleeding kit, fresh brake fluid, and a container to collect the old fluid.
  3. Start by removing the old brake fluid from the reservoir using a turkey baster or syringe, being careful not to spill any on the bike’s paintwork.
  4. Refill the reservoir with new brake fluid of the recommended type, ensuring not to overfill it.
  5. Attach the brake bleeding kit to the brake caliper and open the bleeder valve.
  6. Pump the brake lever slowly and steadily, while keeping an eye on the fluid in the reservoir. Make sure it doesn’t run dry.
  7. Continue pumping until you see clear, bubble-free fluid coming out of the bleeder valve.
  8. Tighten the bleeder valve and remove the brake bleeding kit.
  9. Repeat the process for each brake caliper and wheel.

Flushing and bleeding the brake system should be done periodically or whenever the brake fluid appears dirty or contaminated.

Checking Brake Fluid Quality

Regularly checking the quality of your brake fluid is a simple yet important task to ensure your safety and the optimal performance of your Harley’s braking system. Here’s how to do it:

  1. Locate the brake fluid reservoir, usually mounted on the handlebars or near the engine.
  2. Inspect the fluid level, making sure it is between the minimum and maximum markings.
  3. Observe the color of the brake fluid. Fresh brake fluid is typically clear or slightly yellow. If it appears dark, murky, or has contaminants, it’s time to replace it.
  4. Check for any signs of moisture. Brake fluid should be free from water or other liquids. If you notice any moisture or droplets, it indicates a potential issue with the system and calls for immediate action.

By following these simple steps and periodically checking the quality of your brake fluid, you can maintain a safer and more reliable braking system on your Harley motorcycle.
