Ford Focus III (2011-2021) brake fluid check diagrams & schemes

Do not use any fluid other than the recommended brake fluid as this will reduce brake efficiency. Use of incorrect fluid could result in the loss of vehicle control, serious personal injury or death.

Only use brake fluid from a sealed container. Contamination with dirt, water, petroleum products or other materials may result in brake system damage or failure. Failure to adhere to this warning could result in the loss of vehicle control, serious personal injury or death.

Do not allow the fluid to touch your skin or eyes. If this happens, rinse the affected areas immediately with plenty of water and contact your physician.

A fluid level between the MAX and MIN lines is within the normal operating range and there is no need to add fluid. A fluid level not in the normal operating range could compromise the performance of the system. Have your vehicle checked immediately.

Only use fluid that meets Ford specifications.

Brake fluid level

The brake fluid builds up the pressure that is responsible for the braking of the car. This is one of the most important operating fluids in your Ford Focus. The brake fluid presses the brake pads against the brake discs, which causes the vehicle to brake. It is important to control the amount of fluid in the brake system. Checking the brake fluid level regularly can help you determine if there is any leakage. Too little brake fluid in Ford Focus will make the brakes inoperative.
