Removing air from the brake system (bleeding) is done using the brake pedal. An assistant is needed to perform the work.
If you need to bleed the entire system, you must bleed each brake cylinder in turn. If only one caliper was replaced or repaired, it is usually sufficient to bleed it only.
Bleeding sequence: rear right brake caliper, rear left brake caliper, front right brake caliper, front left brake caliper.
Caution! For vehicles with brake fluid level alarm, turn off the ignition before bleeding.
Remove the cap from the air release valve on the brake cylinder. Clean the valve. Connect a clean hose to it, lower the other end of the hose into a bottle half filled with brake fluid so that the end of the hose is below the fluid level.
Have your assistant press the brake pedal until pressure builds up in the brake system. This will be felt as increased pedal resistance.
Once sufficient pressure has been reached, leave the pedal depressed.
Loosen the air release valve about half a turn. The brake fluid will flow into the bottle. Make sure that the end of the hose in the bottle is always below the fluid level.
Once the fluid pressure drops, tighten the air release valve.
Repeat the process of pressurizing the system. Loosen the air release valve again until the pressure drops, then tighten it.
Continue the process of removing air until no more air bubbles are released from the liquid flowing into the bottle.
After removing the air, disconnect the hose and put the cap on the valve.
Remove air from the remaining brake cylinders in the same way. Caution! When removing air, do not allow the fluid level in the reservoir to drop too much by adding fresh brake fluid. Otherwise, air will be sucked in through the reservoir.
After removing the air, fill the tank with liquid up to the "MAX" mark.
