Why Bleeding Mountain Bike Brakes is Important
At some point, every mountain biker will need to bleed their hydraulic brakes. Brake bleeding is the process of removing air bubbles from the brake lines and replacing the old brake fluid with new, fresh fluid. Bleeding your mountain bike brakes is essential for maintaining optimal performance and safety on the trails.
If you neglect to bleed your brakes, your bike’s stopping power will decrease, and you may find yourself unable to stop effectively. The brake lever feel may become soft or spongy, and you may experience brake fade, where the brakes lose power over time. In the worst-case scenario, your brakes may fail completely, putting you at risk of serious injury.
That’s why we highly recommend bleeding your mountain bike brakes regularly as part of your bike maintenance routine. Not only does it ensure optimal performance and safety, but it also extends the life of your brake system, saving you money in the long run.
DIY Mountain Bike Brake Bleeding
While you can take your bike to a professional for brake bleeding, doing it yourself has several benefits. First, it saves you money on labor costs. Second, it allows you to become more familiar with your bike’s brake system, which can be helpful for troubleshooting issues in the future. Finally, it gives you greater control over the process, ensuring that your brakes are bled exactly how you like them.
To bleed your mountain bike brakes, you’ll need a few essential tools, including a bleed kit, fresh brake fluid, a torque wrench, and a bleed block. These tools are readily available online or at your local bike shop.
Step-by-Step Guide to Bleeding Mountain Bike Brakes
Here is a detailed step-by-step guide on how to bleed your mountain bike brakes:
- Prepare Your Bike: Begin by choosing a clean, well-lit area to work on your bike. Remove the wheel or wheels that need the brakes bled. It is recommended to elevate your bike and secure it in a bike stand or similar device to avoid damaging the frame.
- Gather Your Tools: Ensure that you have all the necessary tools for the job. These typically include a brake bleed kit, a set of Allen keys, and a pair of plastic gloves to avoid coming in contact with the brake fluid. Follow the manufacturer’s instructions to assemble the brake bleed kit properly.
- Remove Old Fluid: Locate the brake caliper bleed screw and open it with an Allen key. Catch the old fluid in a container and dispose of it according to your local regulations. Apply some fresh brake fluid to the bleed screw and tighten it back up. Repeat this process for the brake lever bleed screw.
- Insert Bleed Block: Insert the bleed block into the brake caliper to prevent the pistons from overextending during the bleed process. This will ensure that the brake pads remain in the correct position and that the system is bled properly.
- Attach Bleed Kit: Attach the bleed kit to the brake caliper bleed screw and attach the other end to the syringe filled with fresh brake fluid. Open the bleed screw and slowly push the brake fluid into the system using the syringe. Continue this process until all the air bubbles have been eliminated, and a steady flow of brake fluid emerges from the bleed screw. Tighten the bleed screw and remove the brake bleed kit.
- Repeat on Brake Lever: Attach the syringe to the brake lever bleed screw, and repeat the process from step 5 until all air bubbles have been eliminated, and a steady flow of brake fluid is visible.
- Clean and Reassemble: Wipe the brake caliper and brake lever clean of any spilled brake fluid. Reinstall the wheel and test the brakes to ensure that they are functioning correctly and that there is enough clearance between the rotor and pads. Dispose of any used brake fluid and equipment properly.
By following these steps, you should be able to successfully bleed your mountain bike brakes and restore them to peak performance.
Troubleshooting Tips for Mountain Bike Brake Bleeding
Even with a solid understanding of the brake bleeding process, you may still run into issues. Don’t worry – we’ve got you covered with some valuable troubleshooting tips to help you overcome common challenges.
