Brake Fluid Flush

It is recommended by most vehicle manufacturers that your brake fluid be completely flushed at a minimum of every two years to prevent brake system failure.

While a brake fluid flush is done as part of a log book service if it is part of the manufacturers recommendations – sometimes we might advise you need one outside of the recommended schedule if we feel it's necessary for your safety and we are always happy to discuss the reasons for our recommendations with you.


What happens during a brake fluid flush?

  • The car is placed on the hoist to allow access to the brake system.
  • The old fluid from the master cylinder is drained.
  • Fresh new, quality brake fluid of the correct type is placed in the system.
  • The new fluid is pumped or ‘flushed’ through the system, completely replacing the old.
  • Each brake is allowed to 'bleed' out to ensure there is no air in the lines.
  • The rest of the brake system is checked for any signs of damage or wear that needs attention and advise you if necessary.
  • The vehicle is taken for a test drive.

Remember, if you are towing heavy loads such as caravans and trailers, it is important replace your brake fluid more regularly as the heavy braking that occurs under these conditions can lead to faster breakdown of your brake fluid. 



How much does a brake fluid replacement cost?

A brake fluid flush can cost anywhere from $70 to over $120 depending on the vehicle type and if there are any other repairs required to complete the task. If, during our inspection of your brake system, we identify any other repairs needed to your brakes we will contact you to confirm and discuss before proceeding.

Brake Fluid - Why replace it?

Brake fluid loses its effectiveness over time because it absorbs moisture. Once the brake fluid is contaminated with water it can rust your brakes and vaporise during braking – if left unchecked this will lead to brake failure eventually which is why it is so important to monitor and maintain your brake fluid.

What is brake fluid?

It is the lifeblood of the brake hydraulic system in your car. Brake fluid transfers the pressure you apply on the brake pedal to the brakes at the wheels of your car.

What happens as it ages?

Brake fluid is very hygroscopic, which means it absorbs water. This lowers the boiling point of the fluid and introduces moisture into the components of the brake system.

How does this affect safety?

With a lower boiling point, the heat generated from normal braking can cause old brake fluid to boil, which in turn causes loss of braking pressure or complete brake failure. Which means your brakes could fail to stop you when you need it most – in an emergency.

How can it save money?

The moisture in brake fluid causes brake components to rust internally and need to be replaced earlier than expected. The cost of replacing brake fluid regularly is very low compared to replacing the brake system.

How often should brake fluid be replaced?

Repco Authorised Service recommend every two years. This is in line with most car manufacturers recommendations. But if there is any doubt as to its age we recommend replacing it.
