Is it necessary to change the brake fluid on a Ford Focus?

I've noticed that my brakes feel a bit spongy and I'm wondering if it's time to change the brake fluid on my Ford Focus. How often should I change the brake fluid and what are the consequences if I neglect it?

Yes, it is necessary to change the brake fluid every 2-3 years. Neglecting it can cause damage to your braking system and may even lead to brake failure while driving.

You should follow the manufacturer's recommendations for changing the brake fluid, but it's generally recommended to change it every 30,000-50,000 miles. Neglecting it can decrease braking performance and potentially lead to costly repairs.

It's best to err on the side of caution and change the brake fluid at least every 3 years. Failure to do so can result in air bubbles in the brake lines which can cause dangerous brake failure.
