The power
Brake Booster may appear wet due to excessive assembly fluid during manufacturing or brake fluid that could have been spilled during system fill. To prevent unnecessary replacement of the power steering boosters, perform the following power brake booster leak inspection before replacing the power brake booster. To properly diagnose a leak condition, aid from an assistant may be required. The power brake booster system must be observed while completing this inspection. Do not hold the wheel for more than three seconds at a full stop, as this will increase the fluid temperature in the pump above the operating temperature. On low mileage vehicles, at the joint between the power brake booster housing and end cap 1, light moisture is acceptable. If fluid droplets develop, the power brake booster must be replaced. A leak between the power steering brake booster 2 and the master cylinder is not acceptable. If a leak is present, the type of fluid must be determined. The power steering fluid indicates that the power brake booster needs to be replaced. Brake fluid indicates an issue with the brake master cylinder.
