The brake pump is in one piece with the brake servo.See See descriptions 3330D BRAKE VACUUM SYSTEM The hydraulic braking system reserve fluid reservoir is press-fitted on the top part of the pump.There is an attachment on the reservoir for connecting the hydraulic clutch release system supply pipe.On vehicles equipped with a robotized gearbox the mounting for the pipe connected to the clutch pump is sealed because the engagement and release of the clutch takes place automatically.There is an insufficient fluid level sensor on the reservoir which is activated when the fluid is below the minimum level, signalling this condition to the Body Computer, which then lights up the warning light on the instrument panel.
