Brake pump, reservoir and load proportioning valve

Description 3330C

The brake control pump is integral with the brake servo Characteristic of working principle 3330D brake vacuum system

The hydraulic brake system fluid reservoir is press-fitted to the upper part of the pump.

The reservoir is fitted with an attachment for connecting the supply pipe to the clutch release control hydraulic system.

On cars with a Selespeed transmission, the connection pipe to the clutch pump is plugged because clutch engagement and release are implemented automatically by the hydraulic speed control unit, which comes with a special reservoir.

The reservoir is fitted with a low fluid level indicator, which is activated when the fluid drops below a certain level. This informs the Body Computer, which turns on the warning light on the control panel.
