Importance and replacement of brake fluid
The Importance of Engine Brake Fluid: Why You Should Check and Replace It Regularly?
For the safe operation of engines, it is essential to maintain the appropriate braking system. One of the key elements of this is the brake fluid, which ensures the efficient operation of the brakes and prevents the brake system from failing. But why is brake fluid so important and what role does it play in the daily operation of your motorcycle? Let's take a closer look!
What is the role of brake fluid?
Brake fluid acts as a hydraulic medium that transfers braking force to the brake calipers and brake shoes when the brake lever or pedal is depressed. This causes the brake pads to press against the discs, slowing down the movement of the engine. Because brake fluid operates reliably at high pressures and temperatures, it is crucial to use the correct type and condition of fluid.
What problems can occur with used brake fluid?
-
Increase in water content:
Brake fluid is hygroscopic, meaning it absorbs water from the environment over time. The high water content lowers its boiling point, which can lead to "brake fatigue" during prolonged braking. This can be especially dangerous when braking on mountain roads or at high speeds. -
Air pockets and reduced braking power:
Water or dirt in the fluid can cause air bubbles that impair the transmission of hydraulic pressure. As a result, the brake may feel "soft" or not respond properly. -
Corrosion in the brake system:
Contaminated brake fluid can cause corrosion in the brake pipes and calipers, which can lead to serious failures in the long run.
How often should the brake fluid be changed?
The frequency of changing the brake fluid depends on the type of motorcycle and its conditions of use. As a general guideline, it is recommended to change it every 1-2 years, or more often if the motorcycle is subjected to intensive use (for example, on a race track or in extreme weather conditions).
How can you check the condition of your brake fluid?
-
Check color:
Fresh brake fluid is clear and slightly yellowish in color. If the fluid is dark or cloudy, it's time to change it. -
Braking effect monitoring:
If the brake is slow to respond or the brake lever feels "spongy", this could indicate a problem with the brake fluid. -
Boiling point measurement:
You can use special tools to measure the boiling point of the fluid. If it is too low, it needs to be replaced.
What kind of brake fluid should you use?
You can find the recommended type of brake fluid (DOT 3, DOT 4, DOT 5, etc.) in your motorcycle's manual. It is important to always use the correct fluid, as the wrong type can damage the brake system.
Long-term cost savings
Although changing brake fluid is a minor expense, you can save yourself from major brake system repair costs if you take care of it regularly. Refurbishing a neglected brake system — which may include replacing brake pipes, calipers, discs or the master cylinder — is not only expensive, but also time-consuming. However, with regular maintenance, you can increase the service life of all brake system components.
Summary
The maintenance of the brake fluid is not only important from the point of view of the optimal performance of the brakes, but also an essential part of safe driving. A well-maintained brake system can save lives, so don't neglect inspection and replacement!
