Brake Fluid

Components in the vehicle's braking system are powered by brake fluid. The brake fluid has to work under high pressures and temperatures, absorbing moisture which allows the vehicle to brake smoothly and efficiently. As the brake system operates, a large amount of heat develops in which the brake fluid must maintain and operate at a high boiling point, permitting the vehicle to come to a complete stop. Without brake fluid, you will essentially have no function in your braking system.

What can go wrong?

Overtime, brake fluid will become too saturated with excess moisture, causing it to degrade. Once the moisture levels reach a certain point, the brake fluid will no longer be able to function properly. Another common cause of low brake fluid is a leak; when you step on the brakes, the pedal will go all the way to the floor but not stop the car and as a result, runs the brake system dry.

What can you do?

Proper maintenance is important to protect against corrosion and avoid damage to the vehicle's brakes and engine. As the brake pads begin to wear out, the fluid level will also lower which can be refilled to the "full" indicator but be sure to get a full brake fluid replacement as the fluid will begin to age and not function properly. Always check with your service advisor or owner's manual when a brake fluid replacement is necessary.
