‘Brake It Down’ – Why Change The Brake Fluid?


Why Change The Brake Fluid?

So you have your car in for a service and the garage calls you to say your car needs a brake fluid change? You may be thinking “what on earth is that and why do I need it now?”

Well, it is actually a very important aspect of motoring. Brake fluid is used to transfer force into pressure to ensure effective braking. Over time the fluid absorbs moisture, changing the boiling point and therefore no longer as effective causing ‘spongy braking’.

The brake fluid is stored in a translucent reservoir in the engine bay, often with a yellow cap like the one shown above. You can see the fluid level without having to open the cap which should only be opened when testing or changing the fluid to avoid excess moisture entering the reservoir.


The image above shows how we test the quality and moisture levels in the brake fluid. The cap is removed and we place the metal rods into the reservoir, the light indicates if action needs to be taken sooner than later. The technician will let you know if it was green, amber or red. If the light is red, we recommend you have the fluid changed as soon as possible as your braking will be affected by this.

At Broadbridge Heath Garage we are able to check your brake fluid for free.

So stop by! (if your brakes are working that is)
