Checking the brake fluid level in the hydraulic reservoir of the service brake system (Opel Corsa C)

The brake fluid reservoir is located in the engine compartment.

The reservoir has a transparent body, so the brake fluid level can be monitored from the outside.

The brake fluid level should always be closer to the "MAX" mark.

If the brake fluid level is too low, before removing the plug from the expansion tank, wipe the plug and the area around the plug with a clean rag to prevent any dirt from getting into the brake hydraulic circuit.

Add the recommended brake fluid to the reservoir. Mixing different types of brake fluid can damage the hydraulic system.
