Brake Fluid

Brake Fluid is a type of hydraulic fluid used within the braking system. It transfers the force created when the brake pedal is pushed onto the wheel hub, allowing the vehicle to slow down. The brake fluid needs to have a high boiling point in order to function properly since an excessive amount of heat occurs when the braking system operates. While working under these high pressures and temperatures, the brake fluid absorbs moisture which allows the vehicle to brake smoothly.

What can go wrong?

The brake fluid will begin to age and deteriorate, causing the boiling point to drop which changes the chemical composition. As moisture starts to overcome the brake fluid, it will eventually lose its function and begin to degrade due to the rise in water content. Leaks within the pipes or hoses may occur, running the braking system dry which leads to corrosion and an expensive repair.

What can you do?

The brake fluid will begin to drain overtime and with the correct fluid recommended in your owner's manual, you can top it up to the indicated mark. Although adding more fluid to the already existing fluid may help the vehicle for a short period of time, a full brake fluid replacement is essential as the fluid will not work as well as it once did. A service advisor will be able to recommend when the fluid needs to be changed.
