If your braking system gets contaminated with air the brake may start feeling soft and spongy, affecting the braking efficiency and threatening your safety. For this, you can apply the bleeding technique, and eliminate any air from the system.
Follow these steps:
- First check the brake fluid reservoir under the hood and fill it with fluid until it reaches the maximum level.
- Use a floor jack to lift the car making it easier for you to work on the wheels. Start with the rear wheels.
- Remove the tires after you loosen the lug nuts.
- Locate the bleeder valve near the brake caliper behind the wheel, and remove its rubber cap
- Cover the bleeder screw with a box-end wrench. Connect a plastic tube to the bleeder’s nipple and put the other end into a container.
- Ask someone to pump the brakes a few times and then to hold them pressed. Meanwhile you have to open the bleeder valve to allow the fluid to get out of the system.
- Tighten the screw and ask the assistant to release the pedal.
- Check the reservoir and add more fluid if needed.
- Replace the procedure to the other 3 wheels.
- Put the wheels back and tighten the lug nuts. Lower the car and take the car to a brake test.
