Brake fluid expansion tank (Opel Kadett D)

The reservoir is located in the engine compartment. It has two chambers, one for each brake circuit. The screw cap has a hole that must always be open.

The reservoir is transparent, so you can check the brake fluid level at any time. The brake fluid level should be between the -max- and -min- marks. Top up only with fresh original brake fluid from the company.



Due to wear of the front disc brakes, the brake fluid level decreases slightly. This is normal.

If the brake fluid level drops sharply in a short period of time, this indicates a brake fluid leak.

The leak location must be found immediately. As a rule, this occurs due to wear of the wheel brake cylinder cuffs. For safety reasons, the brake system should be checked in a specialized workshop.
