Don't be intimidated by the thought of bleed brakes of your own bike. With a little bit of know-how, it's a straightforward process that can save you time and money. Plus, being able to do it yourself means you won't have to rely on anyone else for routine maintenance.

In this post, we'll cover everything you need to know about bleed brakes of your own bike - from the tools required to the step-by-step process. So grab your brake fluid and let's get started!

How to Bleed Brakes

Step by Step Instructions on How to Bleed Brakes

Assuming your bicycle has rim brakes, the first step is to remove the wheels. Once the wheels are off, locate the brake pads. The brake pads will be attached to the brake calipers, which are in turn attached to the frame or fork of the bike.

With the brake pads removed, you should be able to see two small metal cylinders. These are the bleed screws. Loosen them with a hex wrench or a Phillips screwdriver, being careful not to strip them.

Now it's time to prepare your syringe or turkey baster. Fill it with mineral oil or DOT fluid—whatever type of fluid your brakes use. Insert the tip of the syringe into one of the bleed screws and depress the plunger.

You should see fluid start flowing out of the other bleed screw. Continue depressing and releasing the plunger until there are no more bubbles in the fluid coming out of the second bleed screw.

Tighten up both bleed screws and reattach your brake pads. You're now ready to reattach your wheels and hit the road!

Keep in mind that this process should be repeated every couple of months, especially if you frequently ride in wet or muddy conditions. Regular bike maintenance will help keep your brakes in top shape and make them last longer!

Tips and Troubleshooting for Possible Issues

There are a few things that can go wrong in the brake bleeding process, but luckily they are all easily fixable! Here are some tips and troubleshooting for possible issues:

  • If your brake lever feels spongy or there is air in the system, bleed brakes again. Make sure to bleed brakes individually until all the air is out of the system.
  •  If your brake pads are not retracting fully after being released, check that the cable is routed correctly and not binding anywhere. You may need to readjust the cable tension.
  •  If your brakes are squealing, clean the brake pads and rotors with rubbing alcohol. Make sure to wipe them dry afterwards. Also, check that the pads are not glazed from excessive heat and replace them if necessary.

With these tips in mind, bleeding your brakes by yourself should be a breeze! 

Good luck!

Benefits of DIY Brake Bleeders


There are several benefits to bleedIng your own brakes

First and foremost, it is much cheaper to bleed brakes than it is to take your bike to a mechanic or bike shop. This is because you only need to purchase the tools once, and then you can use them whenever you need to bleed brakes - mechanics and bike shops will charge you for both the service and the cost of the tools every time.


Second, bleeding your own brakes gives you a chance to inspect other parts of the braking system for wear and tear. This can alert you to potential problems so that they can be fixed before they cause serious damage or render the brake system unusable.

Doing the brake bleeder process on your own means that you will have a complete understanding of how your brake system works. This knowledge can come in handy in the event of future repairs, and it can help you to diagnose problems on your own.

Ultimately, by DIY brake bleeder process you can ensure that your brakes stay functioning properly, that they are safe to ride, and that you save money in the long run.


How Often Should You Bleed Brakes On Your Bicycle?

Assuming you have disc brakes, you'll need to bleed them every so often to get rid of any air that might have gotten into the system. The frequency will depend on how much you ride and in what conditions. A good rule of thumb is to bleed your brakes at least once a year, or more often if you ride in dusty or wet conditions.

To bleed your brakes, you'll need a few tools: a brake bleeder kit, some fresh brake fluid, and a clean rag. You'll also need a helper who can hold the brake lever while you bleed the brakes.

Start by removing the wheel and then the brake pads. Next, attach the bleeder kit to the bleeder nipple on the caliper. Open the bleeder valve and have your helper squeeze the brake lever until fluid starts coming out of the bleeder valve.

Close the valve when there are no more air bubbles in the fluid. Repeat this process until all of the air has been bled from the system.

Once all of the air has been removed, put everything back together and enjoy your freshly bled brakes!
