Question 1

What is Brake Fluid?

Accepted Answer

Brake fluid, or hydraulic fluid enables the other elements of the car’s braking system to bring the car to a halt. The pressure of the hydraulic fluid enables the brake rotors to press down on the brake pads.  The brake pads are then in contact with the wheels, subsequently slowing their rotation and stopping the car.

Question 2

Does Brake Fluid need to be topped up?

Accepted Answer

Brake fluid absorbs moisture from the air and begins to lose its functionality and therefore needs to be changed every year or so.

Question 3

Can I change my brake fluid at home?

Accepted Answer

It is possible, however having the job done professionally by a garage is much safer and more reliable. Garages replace brake fluid with specialist equipment, as oxygen in the air can contaminate the brake fluid if the job is done at home freehand.

Question 4

How do I know when to change my brake fluid?

Accepted Answer

The brake fluid warning light on your dash is the one with the exclamation mark (!) in a circle with two curved lines or brackets on either side. When this light illuminates on your dashboard, you should check your brake fluid level, topping up if necessary. The level of brake fluid required for your vehicle will be noted in your car owner’s manual.
