The importance of inspecting bicycle brakes cannot be overstated. Your brakes are one of the most important safety features on your bike, and they need to be in good working order to keep you safe. https://youtu.be/xEu4gcmwtKk

Here are some of the reasons why it’s important to inspect your bicycle brakes regularly:

✅ To ensure that they are working properly. Brakes that are not working properly can be dangerous. If your brakes are spongy, noisy, or not stopping your bike as quickly as they used to, inspect them.
✅ To check for wear and tear. Brake pads and rotors wear down over time and need to be replaced when they reach a certain level of wear. If you don’t inspect your brakes regularly, you may not know they must be replaced until it’s too late.
✅ To prevent accidents. A bike with faulty brakes is a hazard to the rider and other people on the road. By inspecting your brakes regularly, you can help to prevent accidents and keep yourself and others safe.

Here are some tips for inspecting your bicycle brakes:

✅ Check the brake pads. The brake pads should be at least 1/8 inch thick. If they are thinner than that, they need to be replaced.
✅ Check the brake rotors. The brake rotors should be smooth and free of grooves. If they are grooved, they need to be resurfaced or replaced.
✅ Check the brake fluid level. The brake fluid level should be between the “min” and “max” marks on the reservoir. If the level is low, you need to add more brake fluid.
✅ Check for leaks. Look for any brake fluid leaks, such as wetness or staining around the brake calipers or brake lines.
✅ Test the brakes. Ride your bike and apply the brakes several times. The brakes should be smooth and responsive. If they feel spongy or don’t stop your bike as quickly as they used to, they must be inspected by a qualified mechanic.

By following these tips, you can help to ensure that your bicycle brakes are in good working order and that you are safe on the road.

My passion for bikes started when my parents opened a shop in the 1980s called Parker Bikes (we were located in Parker, Colorado). My love for cycling has continued since then, in my work and with my hobbies of road cycling and mountain biking. After my parents’ shop closed, I worked for other bike shops (including Lee’s Cyclery in Fort Collins), where I built and sold bikes, fixed and tuned up bikes, and managed inventory.
I love working on bikes and want to share my passion for cycling with others. So, next time you’re talking cycling with someone and wondering how to get started or where to go from here, you can think, “I know a guy!”
