Brake fluid naturally absorbs water over time and is recommended to be replaced every two years. Once the water content rises above 3% brakes can fail. The problem occurs because water reduces the boiling point of the fluid, air bubbles are created and braking becomes ineffective.
The problem is made even more dangerous because braking will appear normal until the brake fluid reaches boiling point, this would normally happen after heavy braking down a steep hill, or on a motorway, the brakes become spongy, ineffective and the vehicle fails to stop. It is therefore essential that the old brake fluid is completely removed from the system and changed, we recommend this is done every two years to be sure your brakes are totally reliable.
If you book a brake fluid change at the same time as a service you save £10 on the brake fluid change!
