What is brake fluid?

Brake fluid is usually made from a synthetic or mineral-based formula. It is essential to your braking system and therefore your safety. The fluid transfers hydraulic pressure from the brake master cylinder to your brakes, this in turn allows you to control your stopping speed when driving.

What is it for?

Brake fluid is essential for cars, vans, motorcycles and even some bicycles with hydraulic brakes. It can also be used as clutch fluid, which you'll need if your car has manual transmission. For the vast majority of vehicles, a single fluid is used in both the clutch and brake reservoirs. Check the cap of your clutch fluid reservoir - it should indicate if you need a special hydraulic fluid.

What else do I need to know about it?

Over time moisture diffuses into the fluid through brake hoses and rubber seals, increasing the water content. High levels of moisture may cause the fluid in your car to boil. If your brakes start to feel spongy and ineffective, this may be the issue. If your fluid is low, you probably have a problem such as a leak. Leaks and excessive moisture in the fluid can both result in a loss of hydraulic pressure and braking ability. As such, it needs to be replaced every two years (although long life brake fluids are available such as dot 5.1)
