Brake vacuum system – operattion

The system makes the braking action smoother and more powerful through the action of the brake servo. The brake servo is a pneumatic device that uses the vacuum set up in the intake manifold to make the brake pedal act more powerfully on the pump so

that braking action can be modulated more effectively.

If the vacuum system should fail, brake system operation is still ensured because the connecion between operating pedal and brake control pump remains operational.

Under such emergency conditions, the brake pedal becomes very hard to operate and braking action is not as prompt. It is therefore advisable to drive with extreme care to the nearest authorised service outlet to check the system.
