Brake System

Components of a Brake System

Brake Pads/Shoes: These create friction against the rotors/drums to slow down the wheels. They wear down over time and need regular replacement.

Rotors/Drums: Rotating discs or cylindrical components that provide the surface for the pads/shoes to create friction. They may require resurfacing or replacement when worn.

Calipers/Wheel Cylinders: These hydraulic components clamp the brake pads/shoes against the rotors/drums when the brake pedal is pressed.

Brake Lines & Hoses: These flexible lines transmit hydraulic pressure from the master cylinder to the calipers/wheel cylinders.

Master Cylinder: This converts the force applied to the brake pedal into hydraulic pressure for the brake system.

Brake Fluid: This hydraulic fluid transmits pressure within the system. It needs to be maintained at the proper level and periodically flushed.

Types of Brake Systems in Fleets

Disc Brakes: Most common in modern vehicles, featuring brake pads that clamp onto a rotating disc.

Drum Brakes: Typically found on older vehicles or rear wheels, utilizing brake shoes that press against a rotating drum.

Anti-lock Braking System (ABS): A safety feature that prevents wheel lockup during hard braking, maintaining steering control and minimizing stopping distances.

Effective Brake System Management

Regular Inspections: Pre-trip inspections should include a visual check of brake components for wear and tear, leaks, or damage.

Preventive Maintenance: Performing scheduled brake pad replacements, rotor resurfacing/replacement, and brake fluid changes based on manufacturer recommendations and wear patterns.

Driver Training: Educating drivers on signs of brake problems (soft pedal, grinding noises, increased stopping distances) and the importance of reporting any concerns promptly.

Technology Integration: Some newer vehicles have electronic brake wear sensors that can alert drivers or fleet managers when brake pad replacement is needed.
