Removal of air from the brake system (pumping) done with the brake pedal. An assistant is needed to carry out the work.
If you need to remove air from the entire system, you must sequentially pump each brake cylinder. In the event that only one caliper has been replaced or repaired, it is usually sufficient to bleed air from it alone.
Bleeding sequence: rear right brake caliper, rear left brake caliper, front right brake caliper, front left brake caliper.
Attention! For vehicles with a brake fluid level alarm, turn off the ignition before bleeding.
Remove the cap from the bleeder valve at the brake cylinder. Clean 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 an assistant depress the brake pedal until the brake system is pressurized. This will be felt by the increased resistance of the pedal.
When sufficient pressure is reached, leave the pedal depressed.
Loosen the bleed valve about half a turn. The brake fluid then flows into the bottle. Make sure that the end of the hose in the bottle is constantly below the liquid level.
Once the fluid pressure has dropped, tighten the air release valve.
Repeat the process of pressurizing the system. Unscrew the bleeder 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, put the cap on the valve.
In the same way to remove air from other brake cylinders. Attention! When removing air, do not allow a strong drop in the fluid level in the reservoir by adding fresh brake fluid. Otherwise, air will be sucked in through the tank.
After removing the air, fill the tank with fluid up to the mark "MAX".
