Why do I need a brake fluid change and how does it work?

It’s no secret that your brakes are one of the most important parts of your car, especially when it comes to keeping you safe on the roads. But you need to look after your brakes so they can keep you safe. A major part of that is a brake fluid change – but what is that and what role does it play in maintaining the system?

What is a brake fluid change?

A brake fluid change is a relatively simple flush to complete. Our mechanics drain your system of the old fluid, check for any extra damage or leaks and then refill with fresh, high-quality brake fluid. This process is straightforward and usually takes between 30 and 45 minutes. We may need more time if we find an additional problem such as a leak, but it’s important to repair this as soon as possible. That way, you’ll have full confidence in your brakes once again and you’ll avoid really serious problems later down the line.

Clearly, a brake fluid change is quick and simple to complete and, with major safety benefits at stake, it would be silly to ignore booking yours.

Brake fluid has a finite lifespan, so regular changes are always necessary

As with everything, brake fluid doesn’t last forever. Even without the risk of contamination (which can happen), it absorbs moisture naturally which lowers its boiling point.

And this really affects its performance.

Brake fluid has a natural boiling point of 230 degrees Celsius. When it absorbs water, that can drop to 155 degrees Celsius, which makes it a lot easier to ‘lose’ your brakes under the intense heat braking generates. ‘Losing’ your brakes is an incredibly scary feeling as the pedal will drop straight to the floor and you won’t stop at all.

Manufacturers recommend a brake fluid change every two years. However, if you notice any problems or lose confidence in your brakes beforehand, don’t hesitate to let a professional mechanic look at your braking system.

Your brakes are much more effective

Naturally, your brakes work much better when everything works properly. Refreshed brake fluid decreases your stopping distance and increases confidence in your brakes. That way, you can rely on them when you need them most.

You see, brake fluid provides the pressure that drives the slave cylinder into contact with the brake disc. Without this pressure, your system won’t work at all. That’s why your brake fluid is the most important part of your system so, if your brake fluid isn’t at the right level or boils too easily, you need a brake fluid change immediately.

If you see anything floating in your brake fluid, the colour of your fluid is darker than a light brown or you don’t feel confident in your brakes, book a brake fluid change before the recommended two-year limit.
