How Often Should You Have Your Brake Fluid Flushed and Replaced?

What is Brake Fluid and Fluid Flush


Why You Should Be Flushing Your Brake Fluid

Brakes are an essential component of your vehicle's safety system. Fluid is used to transfer the hydraulic pressure from your brake pedal to your brake calipers and brake pads, which in turn slow down or stop the car. Brake fluid needs to be replaced periodically because its boiling point drops as it gets older.

  1. - Brake fluid is typically blue but can also be red, yellow, or green.
  2. - The boiling point for brake fluid is around 350 degrees Fahrenheit
  3. - Brake fluid should be changed every two years, even if you haven't driven the car much and more frequently if you drive the car a lot.
  4. - You should flush and change your brake fluid every two years or so.

What is Brake Fluid?

Brake Fluid is a clear, non-toxic, water-bad fluid that is used in the hydraulic brakes of automobiles to transfer kinetic energy from the brake pedal to the brake pads. Brake fluid is typically stored in front of the engine.

Brake fluid is the liquid that operates the brake system in cars and other vehicles. It has a central role in providing stopping power and is just one of many fluids used throughout a vehicle’s braking system.

Brake fluid Flush may also refer to hydraulic brake fluid, which is used in hydraulic braking systems for heavy vehicles such as trucks and buses.

Why it's Important to Flush Your Brake System

Brakes are an essential part of the vehicle. They are the only thing that is stopping people from running into other cars or objects in their path. Brake pads work by applying pressure to stop the car when someone steps on the brake pedal.

The pads press against the brake rotor to slow down and stop rotation of it. However, after a certain time period, brake pads start to wear down and lose their effectivity. This leads to inadequate braking power which can be dangerous if it happens while driving on wet or icy roads.

There are three main reasons why your brakes might need a flush: The first reason is when you feel heavy vibrations in your steering wheel while braking- this might be due to air bubbles in your system which can be due to bad o-rings in the master cylinder.

How to Flush Your Car Brakes at Home

One of the most popular ways is to take your brake fluid out and then put it back in after replacing it with fresh fluid. This makes sure that all parts of the brake system get flushed out. You can use this method while you're checking other things like your brake pads too.

Another way is to put some kind of solvent in between the pistons before you push them together, then release them quickly. This will cause bubbles that will loosen up the dirt and grime inside your brake system that might be causing problems with braking power. One example of this solvent is soapy water which helps get rid.

How Long Does Brake Fluid Last in a Car

In ideal conditions, an unopened brake fluid usually lasts around 2 years – that's without the bottle being opened. It's best to always use a new bottle of brake fluid when you need it as moisture will inevitably seep in as soon as the cap is taken off.

You need to be mindful of the different brake systems when choosing a brake fluid. Brake fluids are designed for certain applications. If you apply a brake fluid from one application to an engine, it will most likely cause damage & shorten the life of the brake system.

There are so many brake fluids to choose from, and different suppliers recommend different intervals. Salkus reckons you should change your fluid every six years or 80,000 kilometres (whichever comes first). "For the last 6-7 years, silicone brake fluid has shown up in most all of the new cars. But, in the past it would only show up in high-end cars like Mercedes, BMWs and Lexus.

Now it's starting to show up in domestics, like GM and Ford. With an ABS braking system, some manufacturers use silicone brake fluid, and some don't. It really is specific to the manufacturer.

If you're not sure whether your brake fluid needs changing, quit down to the nearest service centre. They can tell you if there's anything wrong with your brake fluid just by looking at it.


Brake fluid is what keeps your brake system in working order. It’s a kind of hydraulic fluid with an anti-corrosive additive that keeps the metal parts of your car’s braking system from rusting.

Brake fluid is usually blue, but it can also be pink, green, or yellow. It has to be red when refilling it in the car because that’s how you know when its level is low - when you see any color other than red, then its time to refill it.
