How Much does a Brake System Flush Cost?
The braking system on a modern-day vehicle relies on brake fluid to transfer the pressure applied to the brake pedal and use it to force the brake pads or shoes against the rotors or drums and allow the vehicle to slow down and stop.
Brake fluid is hygroscopic, which means that over time, the fluid will absorb moisture and other contaminants from the air and reduce the effectiveness of the braking system.
Air can also enter the system, which will cause the brake pedal to feel spongy.
If left unchecked, this can cause damage to the lines and other braking components and put you and other motorists in danger.
Carrying out a brake system flush will ensure proper system performance and increases the longevity of your braking components.
A full braking system flush usually starts around the $70 mark, and can increase to $120+
Brake System Flush
How is a Brake System Flush Performed?
The mechanic will inspect the condition of the fluid, and if it requires changing, will drain the braking system reservoir and fill it with new fluid.
The vehicle will be raised up to allow access to the brake callipers and drums (if fitted) and the brake fluid will be pumped through via a hand-held vacuum pump or atmospheric pressure, starting at the caliper or drum furthest away from the reservoir.
Once the fluid has been flushed through thoroughly, the reservoir will be topped up and the braking system tested for correct operation.
- The brake fluid will be inspected for condition and contamination
- The reservoir will be drained and filled with new fluid
- The vehicle will be raised up and braking components inspected
- The old fluid will be flushed out and replaced with new fluid
- The braking system will be bled to ensure there is no air trapped in the system
- The fluid will be topped up, and any spills cleaned up
- Test drive vehicle to ensure correct operation
Important Tips to Remember
- Most manufacturers recommend the braking system be flushed every 2 years or 30,000km to keep the system in good working condition. If your vehicle is operated under extreme circumstances or is used to tow large loads, the fluid will need to be replaced more often, usually once a year.
- Most modern vehicles require DOT 4 brake fluid, which has a higher boiling point than older DOT 3 fluid and therefore provides better protection.
- Some modern-day vehicles have ‘Low Brake Fluid’ sensors that alert the driver when the brake fluid is low. If this warning light comes on, have your braking system inspected immediately to determine the cause.
Common Symptoms a Brake System Flush is Required:
- Reduced braking efficiency – vehicle takes longer to stop than usual
- Brake pedal feels spongy
- Brake fluid is black or discoloured due to contamination
How much is a Brake System Flush?
A Brake System flush is an inexpensive way to keep your brakes operating at their best.
A Brake System flush usually starts around $80 and can go up to $200+ if you have performance brakes fitted.
How Important is it to have my Brake System Flushed?
If the fluid is not changed, the effectiveness of your brakes can be reduced, putting you and other motorists at risk in the event of an emergency.
It can also cause premature damage to other braking components which may lead to expensive repair costs.
