Tank of the pump of the hydraulic booster
Level falling below norm leads to failure of the pump of the hydraulic booster.

On a part of cars the tank of the pump of the hydraulic booster is mounted in the left part of a motor compartment. In a stopper of a tank it is built in щуп. On a part of cars the tank of the power steering is incorporated with a tank of the hydraulic booster of brakes.
1. Warm up the engine and idling turn a wheel in both parties, thereby having removed air from system. Turn out a stopper with shchupy, wipe, again wrap a stopper, then again turn out and check level on edge of a film of liquid on щупе. Level of liquid should be between two risks (shooters specified control risks).
2. On cars with the hydraulic booster of brakes press 10 times a brake pedal, unscrew a cap nut, remove a stopper and be convinced that level of liquid is not below 6 mm from the upper edge of a tank.
3. If necessary add liquid.
4. The frequent dolivka of liquid indicates a podtekaniye in hoses of the hydraulic booster, in unions of hoses, in the pump of the hydraulic booster, and also in the steering mechanism, need of careful check and malfunction elimination.
5. Check a tension of a belt of a drive of the pump of the power steering.
