Frequently asked questions about brake fluid change

Do I need to change the brake fluid?

Yes, you definitely need to change the brake fluid! Over time, it absorbs moisture, which lowers its boiling point and weakens its performance. This can cause your brakes to fade, work less effectively, or even fail.

What happens if I don’t change the brake fluid?

If you don’t change your brake fluid, you’re putting yourself in danger – it’s as simple as that. Over time, brake fluid absorbs moisture, lowering its boiling point which makes your brakes less effective. Old brake fluid can also cause corrosion in the brake system, leading to costly repairs.

Can I do a brake fluid flush myself?

You can, but it needs the right tools and know-how. It's usually safer and better to let a mechanic handle it to make sure it’s done right.

How often should I change the brake fluid?

Change your brake fluid every two to three years or every 30,000 miles. Check your car’s manual for exact timing.

Can I mix old and new brake fluid?

No, mixing is a bad idea. Old fluid may have moisture and dirt, which can weaken the new fluid. Always replace all the old fluid to keep your brakes working their best.

What is a brake fluid flush?

A brake fluid flush is when all the old fluid is drained out and replaced with new fluid. This removes moisture and dirt from the brake system, helping it work safely and efficiently.
