Fill the brake system with brake fluid.
Fill the pneumatic drive with compressed air.
Press the brake pedal several times.
Add fluid to the tanks to the required level.
Remove the protective cap of the bleeder valve and install a rubber or plastic hose onto the head of the rear left wheel cylinder bleeder valve.
Lower the free end of the hose into a transparent container partially filled with brake fluid.
Unscrew the bleeder valve one turn, smoothly press the brake pedal all the way and tighten the valve with slight force.
Release the pedal.
This operation should be repeated at intervals of several seconds until brake fluid comes out of the hose lowered into the container without air bubbles.
In this case, it is necessary to monitor the fluid level in the master cylinder tanks and replenish them as needed, avoiding allowing the level to drop below the lower edges of the tanks.
After the appearance of air bubbles stops, tighten the bleeder valve while pressing the brake pedal.
In the same way, bleed the rear right brake and both front brake mechanisms.
Having removed the hose from the bleeding valves, you need to thoroughly wipe the valves and put protective caps on their heads.
When the hydraulic drive is pumped, a pressure difference occurs in its circuits, displacing the piston of the signaling device, as a result of which the warning lamp lights up.
To return the warning device to its original position, you need to unscrew the bleeder valve 1/2 a turn, having first removed the protective cap from it, and, smoothly pressing the brake pedal, ensure that the lamp goes out.
Then, keeping the pedal pressed, close the valve.
If you replace a set of front or rear brake pads, as well as at least one brake disc, it is necessary to break in the pads to the discs using the following method:
- - perform thirty moderate-intensity braking from speed 90 to
30 km/hwith an interval of at least 2 kmbetween stops;
- - perform three effective braking on the verge of wheel locking from a speed of
80 km/hto a complete stop with a minimum interval between braking.
After replacing and running in the pads, it is necessary to check the operation of the brakes in road conditions.
