How to Make Your Own Brake Bleeder

If your vehicle brakes feel spongy or you need to press hard to apply brakes to the vehicle, it is an indication that you need a brake bleeder. the purpose of bleeding the brake is to get rid of the air that has possibly entered the brakes or to remove the grimy fluid out of the brake lines. You have to bleed the brakes even when changing the brakes of the vehicle. To bleed the brakes, it is necessary to lift the vehicle from the ground level. Do not perform this action alone, and make sure not to get under the vehicle unless it is completely safe to do so. Continually check the brake fluid level to prevent air from entering the system. In such cases, the bleeding process will be more time consuming. Follow the steps below to make a brake bleeder on your own.

Tools and Materials

  • Large jar 
  • Brake Fluid 
  • Jack
  • Clear small tubing
  • Assistant

Step 1: Raise the Hood

First, park your vehicle on a leveled ground to raise the hood. Engage the emergency brake for the vehicle before continuing with the next step.

Step 2: Raise the Vehicle

You need to perform this entire process of bleeding the brakes for all the 4 sides of your vehicle, but one at a time. Start with the rear passenger side. Loosen the lug nuts, raise the vehicle using the jack and remove the tire carefully. See to it that your vehicle is well supported. It is important to ensure your safety before proceeding with the next step.

Step 3: Make the Connections

Locate the rotor which is a round metal just behind the tire. Here, you will find the nozzle and a bolt behind it. Connect the nozzle to a clean tubing which in turn is connected to an empty jar. Now, remove the lid of the break fluid reservoir which is under the hood.

Step 4: Remove the Brake Fluid

Slowly loosen the bolts, allowing the fluid to flow into the jar from the tube. Ask your helper to press the brake pedal so that all the fluid comes out and collects into the jar.

Step 5: Release the Air

Once the fluid stops coming out and all the air is released, your assistant might find it difficult to push the brakes. Now, ask him to continue holding the brake pedal until told to stop. Now, it is time to tighten the bolt quickly. Check the brake fluid reservoir and add the fluid if necessary.

Step 6: Replace the Tire

After the bolt is fixed tightly, replace the tire back to its position and carefully release the jack. Put all the lug nuts back and tighten them as well.

Step 7: Repeat the Procedure

You have now removed air out of the brakes in the passenger rear side. Repeat the steps given above for the other 3 sides of your vehicle in the following sequence: the driver's rear side, then the passenger front side and finally the driver's front side. 

Step 8: Test

Finally, test the brakes. If they are still spongy or hard to press, do the procedure once again until you are satisfied with the break settings.
