Most drivers will happily top up washer fluid, check tyre pressures, or book an MOT when it’s due. Brake fluid, on the other side, gets far less focus, simply because it’s tucked away under the bonnet and hardly ever causes obvious problems until something begins to change.
That can be easily forgotten between services. But brake fluid also has a direct impact on how effectively a vehicle stops. As it ages, it absorbs moisture and loses its ability to transmit hydraulic pressure through the brake system. This is a slow process, which explains why many drivers don’t realise there is a problem until the braking performance begins to feel different.
Being aware of the signs to look for can detect the problem early and keep the braking system functioning how it should.
