When it comes to motorcycle maintenance, one of the most critical components to focus on is the brake system. The brake fluid plays a vital role in ensuring the safety and reliability of your motorcycle’s brakes. Over time, the brake fluid can become contaminated, leading to a decrease in braking performance and potentially causing accidents. Changing the brake fluid is a relatively simple process, but it’s essential to do it correctly to avoid any complications. In this comprehensive guide, we’ll walk you through the step-by-step process of changing the brake fluid on your motorcycle, highlighting the importance of this maintenance task and providing valuable tips and tricks to ensure a successful procedure.

Why Change Brake Fluid?
The brake fluid is responsible for transferring the pressure from the brake lever to the brake caliper, allowing the brake pads to clamp onto the rotor and slow down the motorcycle. However, the brake fluid can become contaminated with moisture, dirt, and debris over time, leading to a decrease in its performance. This can cause a range of problems, including:
- Spongy brake feel: When the brake fluid becomes contaminated, it can cause the brake lever to feel spongy or soft, making it difficult to slow down the motorcycle.
- Reduced braking performance: Contaminated brake fluid can lead to a decrease in braking performance, making it harder to stop the motorcycle in emergency situations.
- Corrosion of brake components: Moisture in the brake fluid can cause corrosion of the brake components, leading to expensive repairs and potentially causing accidents.
Changing the brake fluid regularly can help prevent these problems and ensure the safety and reliability of your motorcycle’s brakes. It’s recommended to change the brake fluid every 1-2 years or every 10,000-15,000 miles, depending on the manufacturer’s recommendations and your riding conditions.
Preparation and Tools Needed
Before starting the brake fluid change, make sure you have the following tools and materials:
- Brake fluid: Choose a high-quality brake fluid that meets the manufacturer’s specifications.
- Brake fluid bleeding kit: This kit usually includes a brake fluid reservoir, tubing, and a bleed screw.
- Torque wrench: A torque wrench is necessary for tightening the brake caliper bolts.
- Rag: A rag is useful for cleaning up any spills or messes.
- Workstand or paddock stand: A workstand or paddock stand can help you lift the motorcycle and provide better access to the brake components.
It’s also essential to consult your motorcycle’s service manual for specific instructions and recommendations for changing the brake fluid on your particular model.
Step-by-Step Brake Fluid Change Procedure
The brake fluid change procedure can be broken down into several steps:
Step 1: Prepare the Motorcycle
Start by lifting the motorcycle onto a workstand or paddock stand, making sure it’s securely supported. Remove the seat and any other components that may obstruct access to the brake reservoir. (See Also: Rpm Goes Up When Pressing Brake? Troubleshoot Now)
Step 2: Locate the Brake Reservoir
The brake reservoir is usually located under the handlebars or near the brake master cylinder. Consult your service manual for the exact location on your motorcycle.
Step 3: Remove the Brake Reservoir Cap
Use a wrench or socket to remove the brake reservoir cap. Be careful not to spill any brake fluid when removing the cap.
Step 4: Drain the Old Brake Fluid
Use a turkey baster or a brake fluid extractor to remove the old brake fluid from the reservoir. Be careful not to spill any brake fluid on the motorcycle’s components or the ground.
Step 5: Add New Brake Fluid
Pour new brake fluid into the reservoir, making sure to use the correct type and amount specified in your service manual.
Step 6: Bleed the Brake System
Use a brake fluid bleeding kit to remove any air bubbles from the brake system. Start by attaching the bleeding kit to the brake caliper, then pump the brake lever several times to remove any air bubbles.
Step 7: Repeat the Bleeding Process
Repeat the bleeding process several times to ensure all air bubbles are removed from the brake system.
Step 8: Tighten the Brake Caliper Bolts
Use a torque wrench to tighten the brake caliper bolts to the specified torque value. (See Also: How Much Does it Cost to Refill Brake Fluid? The Real Price Guide)
Step 9: Test the Brakes
Test the brakes to ensure they’re functioning properly. Check for any leaks or signs of contamination.
