Maintaining your motorcycle’s brakes is crucial for ensuring your safety on the road. Properly functioning brakes can mean the difference between life and death, and neglecting them can lead to serious consequences. One of the most important steps in maintaining your motorcycle’s brakes is bleeding the system. In this article, we will guide you through the process of how to bleed a motorcycle brake.
Why Bleed Your Motorcycle Brake?
Bleeding your motorcycle brake is a process that removes air from the brake system, which can cause spongy or soft brake pedal feel. Air can enter the system through various means, such as during brake pad replacement, bleeding, or even a minor collision. When air is present, it can cause the brake fluid to become contaminated, leading to reduced braking performance and potentially causing the brake system to fail.
What is Brake Bleeding?
Brake bleeding is the process of removing air from the brake system by forcing new brake fluid into the system and allowing any air bubbles to escape. This is typically done by attaching a brake bleeding kit to the brake caliper and pumping the brake pedal to push new fluid through the system. The air bubbles will rise to the top of the fluid reservoir and can be easily removed.

How To Bleed A Motorcycle Brake
Bleeding a motorcycle brake system is a crucial maintenance task that ensures the brakes function properly and safely. A faulty brake system can lead to accidents, damage to the motorcycle, and even injury or death. In this article, we will guide you through the process of bleeding a motorcycle brake system, including the necessary tools and precautions.
Why Bleed A Motorcycle Brake?
Bleeding a motorcycle brake system is necessary when:
- The brake fluid level is low
- The brake pedal feels spongy or soft
- The brake lever feels stiff or hard to press
- There are air bubbles in the brake lines
- The brake system has been recently serviced or repaired
Bleeding the brake system removes air from the lines, which can cause the brakes to malfunction. Air can enter the system through various means, such as:
- Leaks in the brake lines or hoses
- Improper installation of brake components
- Corrosion or rust in the brake system
- Using the wrong type of brake fluid
Tools And Materials Needed
To bleed a motorcycle brake system, you will need the following tools and materials:
- Bleed kit for your motorcycle’s brake system (available at most motorcycle dealerships or online)
- Brake fluid (the correct type for your motorcycle’s brake system)
- A clean, lint-free cloth or paper towels
- A pair of gloves (optional)
- A motorcycle lift or centerstand (optional)
Step-by-Step Instructions
Follow these steps to bleed a motorcycle brake system:
Step 1: Locate The Brake Bleed Screws
Find the brake bleed screws on your motorcycle. These screws are usually located near the brake master cylinder or at the caliper. You may need to refer to your motorcycle’s manual or consult with a mechanic if you’re unsure where the bleed screws are located.
Step 2: Remove The Bleed Screws (See Also: Are The Front And Rear Brake Pads The Same)
Use a wrench or socket to remove the brake bleed screws. Be careful not to damage the threads or strip the screws.
Step 3: Attach The Bleed Kit
Attach the bleed kit to the brake master cylinder or caliper, depending on the type of bleed kit you’re using. Make sure the kit is securely attached and won’t come loose during the bleeding process.
Step 4: Open The Bleed Valve
Open the bleed valve on the bleed kit by turning it counterclockwise. This will allow brake fluid to flow out of the system and air to be removed.
Step 5: Pump The Brake Pedal
Pump the brake pedal several times to push any air bubbles out of the system and into the bleed kit. You may need to use a little bit of force to get the air to come out.
Step 6: Check For Air Bubbles
Check the brake fluid reservoir to see if any air bubbles are present. If you see air bubbles, you may need to repeat steps 4 and 5 until the air is removed.
Step 7: Close The Bleed Valve
Close the bleed valve by turning it clockwise. Make sure it’s securely closed to prevent any air from entering the system.
Step 8: Repeat The Process (See Also: How To Change Brake Pads On 2017 Chevy Silverado)
Repeat the process for each brake bleed screw on your motorcycle. Make sure to check the brake fluid level and top it off as needed.
Additional Tips And Precautions
Here are some additional tips and precautions to keep in mind when bleeding a motorcycle brake system:
Use The Correct Type Of Brake Fluid
Make sure to use the correct type of brake fluid for your motorcycle’s brake system. Using the wrong type of brake fluid can damage the system and lead to costly repairs.
Wear Protective Gear
Wear protective gear such as gloves and safety glasses when bleeding a motorcycle brake system. The process can be messy and may involve sharp objects.
Use A Clean Work Area
Use a clean work area to prevent dirt and debris from entering the brake system. Make sure to clean up any spills or drips immediately.
Check The Brake Fluid Level Regularly
Check the brake fluid level regularly to ensure it’s at the recommended level. Low brake fluid levels can cause the brakes to malfunction.
