Bleeding brake system

For reliable operation of the brake system must be removed from the air. Before starting to bleed the system, check the fluid level in the reservoir and, if necessary, top up. Make sure that the timing of replacement of the brake fluid is not passed.

PERFORMANCE ORDER

Check all connections of brake lines for leaks. Check for worn hoses and whether there are no cracks on them and cuts. If you doubt the brake caliper or wheel cylinder should inspect them for signs of fluid leakage. Prepare a clean vessel, the length of rubber tubing that would firmly sat on the drain valve and brake fluid. First bleed the master cylinder (see. Removal of air from the master cylinder). Loosen the nut in place of the hydraulic line connecting the master cylinder. Ask the assistant to slowly drown the brake pedal to the floor, forcing the air in the master cylinder, exit through the loose connection. When fully pressed pedal tighten. Release the pedal. The pedal should not be let go as long as you do not last connection because otherwise, air may get into the cylinder. Repeat this process as long as the cylinder is no longer leave the air. Hydraulic system bleed separately, starting with the longest line (back). For pumping the brake system, clean the surface near the drain valves. Remove from the drain valve and put the rubber cap on the nipple length of rubber tubing. Lower the other end of the tube into the vessel, which should be poured as much brake fluid that during pumping end of the tube remains immersed in it. Open the drain valve about 3/4 of a turn and ask the assistant to slowly drown the brake pedal to the floor and hold it in this position. Close the drain valve and release the pedal. Perform this operation for as long as there will not cease to leave air vials. Pumping system, periodically check the fluid level in the reservoir. It should be filled up to the top, or get back in the air. Do not top up the reservoir fluid already pumped out of the system. Repeat the procedure for the second rear wheel. Bleeding the front brake system is carried out in a similar manner. Fill the master cylinder fluid so that the level in the tank was about 6-7 mm below the upper edge. Check the operation of the brake fluid level indicator by pressing the black rubber bulb on top of the tank (ignition). The lamp on the instrument panel should light up. Check feeling on the brake pedal: it must be tough and not let the feeling of failure ("viscosity"), which is a sign of the presence of air in the hydraulic drive.
