Brake fluid is a fundamental component of the lorry's hydraulic brake system. It transmits hydraulic pressure from the master cylinder to the wheel cylinders or calipers at each wheel. When you press the brake pedal, the master cylinder generates hydraulic pressure, which is transferred through the brake lines filled with brake fluid.
Force Multiplication:
Brake fluid plays a crucial role in multiplying the force applied to the brake pedal. The mechanical force you exert on the pedal is converted into hydraulic pressure by the master cylinder. This pressure is amplified as it travels through the brake fluid to the wheel cylinders or calipers, generating the necessary force to actuate the brake pads or shoes against the rotors or drums.
Heat Dissipation:
During braking, the conversion of kinetic energy into heat can cause the brake components, especially the rotors or drums, to generate immense heat. Brake fluid acts as a heat transfer medium, absorbing and dissipating heat away from the brake system. This prevents overheating and ensures consistent braking performance.
Corrosion Protection:
Brake fluid serves as a protective barrier against corrosion within the brake system. It protects metal components, such as brake lines, calipers, and wheel cylinders, from rust and corrosion, ensuring their longevity and reliable operation.
Lubrication:
In certain brake systems, brake fluid provides lubrication to moving parts, including pistons and seals within the master cylinder, wheel cylinders, and calipers. This lubrication reduces friction and wear, contributing to smoother and more efficient brake operation.
System Maintenance:
Regular checks of brake fluid condition and level are essential for maintaining the health of the braking system. Brake fluid can deteriorate over time due to moisture absorption and contamination, affecting its performance and safety. Therefore, it is important to follow the manufacturer's recommendations for brake fluid maintenance, including periodic replacement and flushing of the brake system.
