Every driver knows how to step on the brakes to make their car stop but not many know how the brake system in their car works, even more so when it comes to maintaining the brakes system.
Q: What is a brake system?
Answer: the brake system consists of a series of hoses filled with brake fluid in order to transfer the force when you step on the brake pedal to the brake callipers in order to stop your car.
Q: What is brake fluid?
Answer: Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in cars, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force.
Q: What will happen if we don't replace the brake fluid over a long period of time?
Answer: Air bubbles may form when the brake fluid exceeds the boiling point during a long distance drive or excessive braking. If there are air bubbles formed in the brake system, only the air bubbles are compressed when we step on the brakes. This also means that the braking force can hardly be transmitted or, in the worst case, no longer be transmitted at all.
Q: How often do we need to change our car’s brake fluid?
Answer: There is no set time to change the brake fluid in your vehicle. The timing varies by type of car, the driving conditions you typically encounter, and the manufacturer's recommendations.
Properties of LIQUI MOLY Brake Fluid Dot 4:
- Miscible and compatible with high-quality synthetic brake fluids
- Outstanding protection against the formation of steam bubbles
- Excellent elastomer compatibility assures a high degree of lubricating action on all moving components in the hydraulic brake circuit
- Extremely high wet and dry boiling points
- Excellent viscosity / temperature properties
- Excellent low temperature behaviour
- Highest thermal stability
Q: What is the boiling point of this product?
Answer: Liqui Moly DOT 4 Brake Fluid has a dry boiling point of 260 degrees Celsius and a wet boiling point of 155 degrees Celsius.
Q: What is dry boiling point and wet boiling point?
Answer: The dry boiling point refers to the brand new fluid. When it's been in use for a while, the boiling point drops due to water contamination. The wet boiling point refers to the fluid that's been in use for a while and has a certain amount of moisture mixed in.
Q: Can I use this product for my motorcycle?
Answer: Yes! You may use it! But, we will recommend to follow the manufacturer recommendation for the brake fluid rating.
Q: Why it is recommended to use this product?
Answer: It contains inhibitors to prevent the corrosion of metallic brake components and to reduce oxidation at increased temperatures. The brake fluid also has a high wet and dry boiling point, thus ensuring safe braking even after the absorption of some moisture over an extended period of use. Other than that, special moisture scavengers inside the brake fluid help to prevent against the formation of steam bubbles.
Q: What is the best way to maintain your brake system?
Answer: To ensure that the brake system works optimally, the following is necessary:
- A regular service and replacement of the brake fluid must be performed (depending on the quality, within 1 to 3 years) and;
- A brake fluid which complies with the legal and technical standards as well as the manufacturer's instructions must be used!
