What is a Brake Flush?

Brake flushing is a routine that is highly recommended when your brake starts showing little signs of fault. Brake flush involves the process of draining out brake fluid from the car’s brake system and replacing it with pure and new brake fluid. 

Like you flush out dirty of unwanted fluid and liquid content from any parts of your vehicle, brake flushing also involves a similar idea behind it. However, the process might be different. For instance, you can decide to get rid of the transmission fluid or engine oil.

Brake flushing requires the removal of the entire brake fluid content from your car’s engine system and replacing it with new and better fluid.

However, brake bleeding involves the flushing out of a part of the brake fluid. Brake bleeding only occurs when you found out that there is the presence of air bubbles in your car’s brake fluid. in this case, you will flush out the portion that is contaminated with bubbles while leaving the rest in the brake system.

Benefits of Brake Flush

The brake, like many other components of a vehicle, is susceptible to damage and contamination, despite frequent maintenance routine. From the master cylinder’s valves to the brake pedal, brake calipers, and wheel cylinders, the brake system features parts that can damage or degrade over time. deteriorate. There are also parts of the system that can accumulate dust, debris, or particles that can contaminate the system.

Besides, it is very important to do a brake flush because most times metal particles and dust can accumulate in joints, and contaminate brake fluid, hence making them black and dirty. But when you flush your brake system, you will change and replace the dirty fluid with clean brake fluid.

Break fluid helps get rid of moisture in the brake system. If there’s excess moisture in brake fluids, it increases its temperature by causing an air bubble in brake fluid. If this air bubble settles in the brake system, results in spongy brake pedals because the air bubble has a lower boiling point and as such compressible, thereby contaminating brake fluid. 

Debris, moisture, and metal particles are capable of reducing braking power, and if the brake is not flushed in time can result in other damages.
