Brake Fluid Flush: Ensuring Safety & Prolonging Your Car’s Health

Brakes are essential components of any vehicle, and their optimal performance is dependent on the quality and condition of the brake fluid. Brake fluid degrades with time and needs to be flushed on a regular basis to keep the car operating safely. Let us examine the significance of a brake fluid flush and how to tell when your car requires one.

 

Understanding the Brake Fluid Flush

The process of replacing old, degraded brake fluid with new fluid is called a brake fluid flush. When you engage the brake pedal, the brake fluid travels from the master cylinder into the brake lines, which in turn activates the brake pistons. These pistons then exert pressure, making the brake pads press against the rotor, bringing your car to a stop.

 

The brake fluid behaves differently depending on whether your vehicle has a disc or drum brake system. In a disc brake system, it activates calliper pistons, creating friction to stop the car, however, in a drum brake system, it forces brake shoes against drums to slow and stop the vehicle.

 

Why Is a Brake Fluid Flush Essential?

Brake fluid absorbs moisture over time. Brake fluid is estimated to absorb between 1.5% to 3% moisture annually. In humid climates, this rate can be even higher. While this helps reduce internal system corrosion, excess moisture can degrade the brake fluid’s performance. The water content can lower the boiling point of the brake fluid, causing it to become ineffective and risking brake failure. Regularly doing a brake fluid flush helps prevent this moisture buildup and ensures the overall safety and responsiveness of the brakes.  

 

Signs You Need a Brake Fluid Flush

One of the first signs that your brake fluid is deteriorating is if the pedal feels softer or spongier than usual, requiring you to push it down further to come to a complete stop. Another red flag is if the ABS (Anti-lock Braking System) or brake fluid warning light appears on your dashboard. Usually, this indicates a problem caused by low brake fluid or a brake fluid leak. The brake fluid may also be the cause if you notice that your car is not stopping as quickly as it used to. 

 

When you brake, you should also be aware of any strange grinding noises or the smell of burning, as these are urgent indicators that the brake system needs to be serviced. Beyond these signals, routine maintenance dictates that you should think about doing a brake fluid replacement about every 45000 km, or roughly every two years, even if everything appears to be functioning smoothly. For any specific maintenance instructions, it is imperative to consult the owner’s manual of your vehicle.

 

The Flushing Procedure

When you arrive for a service, the team first locates the brake fluid reservoir to drain the old brake fluid. The car is elevated, and all wheels are removed to access and drain the fluid from each brake valve. Old fluid is directed into a disposal container using tubes attached to each brake valve. Two technicians collaborate during the procedure; one handles the brake valve while the other pumps the brakes.

 

Once the old fluid is drained, it’s replaced with fresh brake fluid. After completing the procedure on all four brakes, the technicians conduct a road test. This ensures the brakes’ smooth and safe operation.

 

Professional Service vs. DIY

While it’s feasible for avid DIY enthusiasts to perform a brake fluid flush at home, it isn’t recommended. Professionals are equipped with specialised machines to ensure a comprehensive and efficient job. By making use of a professional service centre like Sharp Brake, you can rest assured that your brakes will be in perfect working order after the brake fluid flush is complete.
