Solve the brake problems by bleeding the system
Today’s cars and motorcycles use braking system with hydraulic system based on braking fluid. They are very efficient and powerful, but in time the system gets contaminated with air bubbles and the brake pedals start feeling very soft and spongy, reducing the braking capabilities. This problem can be solved by bleeding the system, meaning getting out the air from the hydraulic system.
Follow these steps:
- Remove the cover from the master cylinder after unscrewing the blots that hold it. After that fill the reservoir to reach the top level.
- Look for the bleeder valve on the brake caliper behind the wheels. On top of the valve there is a rubber cap used to protect against dust, remove it.
- Connect the valve with a plastic tube and put the other end into a plastic container.
- Rotate the valve ½ a turn counterclockwise.
- Start pushing the brake pedal, and then hold it pressed. Contaminated brake fluid should pour out from the system and into the container.
- Close the valve while the pedal is still pressed. Release the pedal and refill the reservoir with fluid.
- Repeat steps 4, 5, 6 until the fluid coming out of the system is clean and free of air bubbles. Close the valve and remove the tube. Refill the master cylinder and put back the cover over it.
