Checking the tightness of the hydraulic booster

1. Ask the assistant to turn the steering wheel all the way to both sides and leave it for a short while in this position.

2. At this point, the system generated maximum pressure and possible leakage of the working fluid will occur.

3. Inspect the area underneath the vehicle steering gear.

4. Also check the power-steering pump and all places of connection of hoses. Leaking hydraulic fluid indicates a leak place.
