A bleeding process that uses a vacuum bleeder to pull the air and old brake fluid from the system.

A device used to measure the amount of vacuum (pressures below atmospheric pressure) an engine can generate during various operating conditions.

A device on a hydraulically controlled transmission that converts engine manifold vacuum into an engine load signal called modulator pressure.

A device used to evacuate the air-conditioning system and put it into a deep vacuum or low pressure to remove moisture.
