Perform bleeding as follows:
CAUTION! While bleeding, timely fill up the liquid in the reservoir of the main cylinder, not allowing the level of
liquid in the reservoir to decrease below “MIN” mark. Do not allow air to enter the system.
If air enters the brake system of a vehicle equipped with ABS, ESP, visit a service station. Never operate the vehicle
until the fault is eliminated.
1. Pump the right and left rear brake cylinder, front pressure regulator circuit (for vehicles which are not
equipped with ABS), right and left front brake cylinder, and right and left front brake cylinder in sequence.
2. Remove the cap from the wheel cylinder blow-off valve and put a special rubber hose about 400 mm long on
the valve.
The other end of this hose dip in a transparent vessel with a capacity of at least 0.5 liters, half filled with brake fluid.
3. Press the brake pedal sharply 3-5 times and, while keeping the pedal pressed all the way, unscrew the blow-off
valve 1/2-3/4 turns, releasing a portion of the liquid from the system into the valve. Tighten the blow-off valve. Tighten
the blow-off valve while the brake pedal is depressed.
Repeat this operation until the termination of the release of air bubbles from a hose that has been lowered into a
vessel with brake fluid.
4. After pumping is complete, wrap the valve and remove the hose. Wipe dry the valve head and put on the
protective cap.
Add brake fluid to mark “MAX” into the reservoir of main cylinder.
Screw the reservoir cap. Tighten the cap by applying a force preventing it of breakage.
Keep the end of the hose immersed in liquid during the pumping process.
Check the operation of the brake system while the vehicle is moving. With proper adjustment of the brakes, its drive
and the correct bleeding of the brakes, full braking should provided within 1/2-2/3 of the pedal stroke.
It is not recommended to add brake liquid collected to the vessel during bleeding into the reservoir of the
main cylinder.
If at least one drum is removed, do not depress the brake pedal, as the pressurized fluid will squeeze the pistons out
of the wheel cylinders and leak out.
For trouble-free brake operations (especially with ABS), change the brake fluid every two years. Replace
