It is recommended recreational riders should bleed their brakes after forty hours of riding, while racers should be bleeding their brakes after not more than twenty hours. If you want to get the most out of your bike's brakes, we recommend bleeding your brakes after every race. It's important to perform maintenance to your bike on a routine basis, because brake fluid deteriorates over time by absorbing moisture and air thus causing the brakes to feel squishy and losing performance. In this article we will describe the step-by-step process, as well as describe the tools needed to perform a brake fluid change.

Step #1: Inspection

Before you begin to change the fluid, inspect the entire brake system. Check your brake pads, if they are below 1mm then it's time for a change. Check the brake rotors for straightness and thickness by spinning the wheel to check for warping. Check your pad springs, retainers, and brake pin for wearing or damage also. Lastly check brake levers as well and replace if bent or worn.

Step #2: Add Brake Fluid

Before pouring any fluid into your bike, clean the area around the reservoir to keep any dirt or grime out of the lines. With the correct brake fluid (DOT 3, 4, 5, or 5.1) top up the brake reservoir.

Step #3: Bleed the Brakes

Locate the nipple on the brake caliper. With a brake-fluid container to catch the fluid, remove the rubber cap and give the brake lever two to four pumps. Using an open ended spanner, loosen the nipple while keeping pressure on the lever. Fluid will begin to come out of the nipple and the lever will soften. Tighten the nipple and then let go of the lever. You will need to repeat this process until new fluid begins to come out of the nipple. While this is happening, continue to top up the reservoir to keep air from entering the lines. After new fluid is bleeding out from the nipple, top up the reservoir one last time and put the rubber diaphragm back in place and screw the reservoir cap back on. That's it! The brake fluid change is complete.

Step #4: Disposing of Fluid

Brake fluid is flammable and needs to be properly cared for after changing your fluid. You should never pour the fluid on the ground, dump down the drain or into the toilet. Unfortunately, trash-pickup companies will not take the fluid. We recommend storing the fluid in the sealed brake fluid container used during the process. Once it is sealed and safe to transport, locate your local city or county government hazardous waste facility to donate your brake fluid.

Taking charge of your own maintenance is the best way to understand your bike while also being able to save you time and money. We hope this article leads you in the right direction in finding the right products and the correct method for the next time your brake fluid needs a change!
