Brake fluid: how to check your car's brakes

Brake fluid: how to check your car's brakes

It’s worth checking your brake fluid level while you have the bonnet open. If the level is low it could indicate a dangerous leak in the braking system.

  • Check your brake fluid whenever you have the bonnet open
  • It takes only a minute to check your brake fluid levels
  • If the level is low, it’s worth getting it checked out by a mechanic

Most other fluids, such as gearbox oil and power-steering fluid don’t need checking outside of routine servicing, but it’s worth checking your brake fluid level while you have the bonnet open. If the level is low, or falling quickly, it could indicate a potentially dangerous leak in the braking system that could lead to brake failure.

The brake fluid reservoir is on top of the master cylinder, which is usually located in one of the back corners of the engine compartment. Just as for other car fluids, the brake fluid level should sit near the high marking on the reservoir.

If you need to top up the level, check the owner’s manual, or call NRMA motoring advice on 13 11 22, for the right kind.
