Incompressibility: Liquids are virtually incompressible, meaning their volume remains constant under pressure. This property ensures that the force applied to the brake pedal is efficiently transmitted to the brake pads without any significant loss.
Low viscosity: Brake fluids need to flow easily through the brake lines and components to transmit pressure quickly. Low viscosity allows for rapid response and effective braking.
Stability: Brake fluids should remain chemically stable over a wide range of temperatures and conditions, including exposure to moisture and air. Stability ensures consistent performance and prevents corrosion or damage to the brake system components.
Lubricity: Brake fluids also provide some lubrication to the moving parts within the brake system, helping to reduce wear and tear and extend the life of the components.
Compatibility: Brake fluids must be compatible with the materials used in the brake system, such as rubber seals and hoses, to avoid any adverse reactions or damage.
Hygroscopic nature: While it may seem counterintuitive, the hygroscopic nature of brake fluids (their ability to absorb moisture) is actually beneficial. Moisture in the brake fluid can raise its boiling point, further enhancing the fluid's ability to withstand high temperatures.
Overall, the properties of liquids, particularly their high boiling point, incompressibility, low viscosity, stability, lubricity, compatibility, and hygroscopicity, make them ideal for use in brake systems to ensure effective and reliable braking performance.
