As a crucial part of your carís functionality, brakes are typically at the top of the priority list when it comes to checking that the various elements of your car are working the way that they should.
There are multiple components of your carís brakes that need to be working together to keep things running smoothly. There are some that weíve heard more about than others - such as the brake pedal, brake lines, brake disks and brake pads.
Brake fluid, also known as hydraulic fluid, is an essential aspect of your brakes. It not only amplifies your carís braking force but it also acts as a lubricant and prevents corrosion in moving parts of your brakes. Simply put, without brake fluid, your brakes wouldnít work. You can find out more about why brake fluid is important here.
The braking system
So, as such an important part of your brake system, how does brake fluid work?
Brake fluid is part of the braking process from the moment you put your foot down to brake. When you press down on your brake pedal, the pistons inside the master cylinder, which lives within the engine compartment, compress to allow the brake fluid to travel under pressure. The compression from the pistons increases the pressure within the brake lines which is where the pressurised brake fluid is contained.
The brake lines divert the force of you pushing down on the brake pedal into the front and rear brakes of your car using the pressurised brake fluid. The brake fluid then uses the energy used to push down the brake pedal to be converted into braking pressure that causes the brake pads to squeeze the brake rotors. This leads the rotors to slow down and brings them to a halt.
Looking to learn a bit more about your carís brakes outside of the brake fluid? We have plenty of information available for you to get to grips with on our brake information page.
Keeping your brake fluid at its best
Your brake fluid is best when it is fresh and uncontaminated, as this means your brake system is working properly and brakes efficiently when you put your foot down on the brake pedal.
As the brake fluid also acts as a lubricant to other moving parts of your braking system, it can absorb any moisture that might come from those components. Because of the elements of the car that the brake fluid comes into contact with when you brake, it is subjected to high temperatures.
The more water that enters your brake fluid, the further diluted it becomes. This then lowers the temperature at which the fluid boils at which can result in your brakes failing to stop your car. By ensuring that your fluidís boiling point is checked, you can keep your brake fluid at its best and prevent any braking accidents that could occur.
