How to check the brake fluid level on a Citroen C3

Locate the brake fluid reservoir to the right of the engine bay, near the firewall.

Do not open the yellow cap.


You can see the brake fluid level MAX marked on the side of the brake fluid reservoir container.

There should be a level of fluid visible that is a slightly darker colour than the plastic reservoir.

Form this you can see if the level is below the max mark.


Don't assume there is a problem if the brake fluid is below max mark, and do not be tempted to top up the brake fluid level.


The brake fluid level is filled to max when all the brake pads and brake discs/drums are new. As the brake pads wear the fluid level drops, correctly. When the brake pads are renewed the level rises again.

If you suspect the level is too low you should have the braking system inspected immediately.

The excessively low level could indicated over worn brake pads and discs/drums or a leak of brake fluid (probably at the rear wheel cylinders). All or any of these problems could lead to a lack of braking efficiency/no braking power.



The 'top up to the max level' is there to use when new pads and discs are fitted and a brake fluid flush is performed to remove the old, work brake fluid and refill it with fresh, clean brake fluid. This is the only time that the brake system should be topped up to the MAX line.
