| 主权项 | 1. A method for conserving vacuum, comprising: providing vacuum to a brake booster to apply vehicle brakes when a vehicle is stopped; and stopping brake booster vacuum consumption in response to a vacuum level in a working chamber of the brake booster being less than a threshold vacuum level that stops the vehicle from moving when the vehicle is stopped. | ||
