How To Bleed Harley Brakes?

How to Bleed Harley Brakes

Harley-Davidson motorcycles are known for their powerful engines and stylish design, but they’re also known for their powerful brakes. If your Harley’s brakes are starting to feel spongy or unresponsive, it’s time to bleed them. Bleeding your brakes is a relatively simple task that can be completed in about 30 minutes with basic tools. In this article, we’ll walk you through the steps of bleeding your Harley’s brakes, so you can get back to enjoying your ride safely.

What is Brake Bleeding?

Brake bleeding is the process of removing air from the brake lines. When you apply the brakes, fluid is forced through the brake lines and calipers to the brake pads. If there is air in the brake lines, it can cause the brakes to feel spongy or unresponsive. Bleeding the brakes removes the air from the lines, so that the fluid can flow freely and the brakes can work properly.

When to Bleed Harley Brakes

You should bleed your Harley’s brakes if you notice any of the following:

  • The brakes feel spongy or unresponsive.
  • The brakes make a squealing or grinding noise.
  • The brake pedal goes all the way to the floor when you apply the brakes.
  • The brake light comes on when you’re not applying the brakes.

How to Bleed Harley Brakes

To bleed your Harley’s brakes, you’ll need the following tools:

  • A brake bleeder kit
  • A 10mm wrench
  • A 17mm wrench
  • A clear plastic container
  • Brake fluid

Step-by-Step Instructions

1. Park your Harley on a level surface and set the parking brake.
2. Remove the brake reservoir cap.
3. Connect the brake bleeder hose to the bleeder valve on the caliper.
4. Fill the clear plastic container with brake fluid.
5. Place the end of the bleeder hose in the container.
6. Open the bleeder valve by turning it counterclockwise.
7. Pump the brake pedal until fluid flows out of the bleeder valve and into the container.
8. Close the bleeder valve by turning it clockwise.
9. Repeat steps 6-8 until the fluid that comes out of the bleeder valve is clear.
10. Reconnect the brake reservoir cap.
11. Test the brakes by riding your Harley around the block.

7. Repeat steps 4-6 for all of the bleeder screws on the calipers.
8. Check the brake fluid level in the reservoir and add more fluid if necessary.
9. Inspect the brake pads for wear and replace them if necessary.
10. Test the brakes to make sure they are working properly.

Bleeding the brakes on a Harley-Davidson motorcycle is a relatively simple task that can be completed in about 30 minutes. It is important to bleed the brakes regularly to ensure that they are working properly and to prevent them from becoming contaminated with air.

By following these steps, you can safely and effectively bleed the brakes on your Harley-Davidson motorcycle.

3. Bleeding the Brakes

Bleeding the brakes is a necessary maintenance procedure that removes air from the brake lines. Air in the brake lines can cause the brakes to feel spongy or unresponsive. It can also lead to decreased braking performance and increased stopping distances.

To bleed the brakes on a Harley-Davidson motorcycle, you will need the following tools:

  • A bleeder wrench
  • A clear plastic hose
  • A container to catch the brake fluid
  • Brake fluid
  • A rag

Step 1: Prepare the Motorcycle

1. Park the motorcycle on a level surface.
2. Turn off the engine and allow it to cool down.
3. Engage the parking brake.
4. Remove the seat.
5. Locate the brake fluid reservoir.
6. Remove the cap from the brake fluid reservoir.

Step 2: Connect the Bleeder Wrench

1. Connect the bleeder wrench to the bleeder screw on the caliper.
2. Make sure that the bleeder wrench is tight enough to prevent the bleeder screw from coming loose, but not so tight that it damages the bleeder screw.

Step 3: Open the Bleeder Screw

1. Open the bleeder screw slightly.
2. Be careful not to open the bleeder screw too much, as this could allow too much brake fluid to escape.

Step 4: Pump the Brake Lever

1. Pump the brake lever until fluid comes out of the bleeder screw.
2. Continue to pump the brake lever until the fluid coming out of the bleeder screw is clear.

Step 5: Close the Bleeder Screw

1. Close the bleeder screw.
2. Be careful not to tighten the bleeder screw too much, as this could damage the bleeder screw.

Step 6: Repeat Steps 3-5 for Each Caliper

Repeat steps 3-5 for each caliper on the motorcycle.

Step 7: Inspect the Brake Pads and Rotors

1. Inspect the brake pads for wear.
2. Replace the brake pads if they are worn down to the wear indicators.
3. Inspect the rotors for damage.
4. Replace the rotors if they are damaged.

Step 8: Replace the Brake Reservoir Cap

1. Replace the cap on the brake fluid reservoir.
2. Make sure that the cap is tight enough to prevent the brake fluid from leaking.

Step 9: Test the Brakes

1. Test the brakes to make sure they are working properly.
2. Make sure that the brakes are not spongy or unresponsive.
3. Make sure that the brakes are providing adequate stopping power.

Bleeding the brakes on a Harley-Davidson motorcycle is a relatively simple procedure that can be completed in a few minutes. By following these steps, you can ensure that your brakes are working properly and that you are safe on the road.

How do I bleed Harley brakes?

1. Prepare your tools and materials. You will need:

  • A Harley-Davidson brake bleeder wrench
  • A clear plastic hose
  • A container to catch the brake fluid
  • A new brake fluid reservoir cap
  • DOT 4 brake fluid
  • A rag
  • Safety glasses

2. Warm up the brakes. Ride your motorcycle for about 10 minutes to warm up the brakes. This will help to thin the brake fluid and make it easier to bleed.

3. Locate the bleeder valves. The bleeder valves are located on the top of each brake caliper. They are small, cylindrical valves with a hex head.

4. Remove the bleeder caps. Use the brake bleeder wrench to loosen the bleeder caps.

5. Attach the clear plastic hose to the bleeder valve. Make sure the hose is long enough to reach the container you are using to catch the brake fluid.

6. Pour some brake fluid into the reservoir. Add enough brake fluid to cover the bottom of the reservoir.

7. Start the engine and hold the front brake lever in. This will apply pressure to the brake system and help to push the old brake fluid out of the calipers.

8. Pump the brake lever repeatedly. Pump the brake lever repeatedly while your assistant opens and closes the bleeder valve. This will help to push the old brake fluid out of the caliper and replace it with new brake fluid.

9. Close the bleeder valve. Once the brake fluid coming out of the hose is clear, close the bleeder valve.

10. Repeat steps 5-9 for the other brake caliper. Repeat steps 5-9 for the other brake caliper.

11. Top off the brake fluid reservoir. Once you have finished bleeding the brakes, top off the brake fluid reservoir with new brake fluid.

12. Install the new brake fluid reservoir cap. Install the new brake fluid reservoir cap.

13. Test the brakes. Take your motorcycle for a test ride and make sure the brakes are working properly.

What are the symptoms of a bad Harley brake bleeder?

  • Brakes that are spongy or don’t feel like they are providing enough stopping power.
  • Brakes that squeal or make a high-pitched noise when you apply them.
  • Brakes that fade after you have been riding for a while.
  • Brakes that lock up when you apply them.
