Changing brake fluid

Car manufacturers recommend changing brake fluid every two years.

recent research revealed that 86% of car owners do not check their brake fluid levels and do not have it replaced at recommended intervals.

some garages may also fail to check or advise customers to change their brake fluid.

The same research also found that 68% of all motorists claimed to be unaware that brake fluid needs changing as a part of a vehicle service.

Why does brake fluid need to be changed?

brake fluid is 'hydroscopic' this means it naturally absorbs water over a period of time, Which in turn reduces the efficiency of the braking system. This occurs because the water reduces the boiling point of the brake fluid, air-bubbles are created and braking efficiency is lost. Only 3% of water content is necessary for this to happen!

The biggest problem is that the brakes may seem quite normal until they reach boiling point, which can happen during hard braking on a steep hill, whilst towing a caravan or on a fast stretch of road.

At this point the brakes may begin to feel spongy and the vehicle may fail to stop.

The solution

The good new is that braking problems can be eliminated by proper servicing of the braking system.
Your local garage can test the brake fluid for water and advise you on whether a brake service is required.
