Brake Testing

Here are the main types of vehicle brake testing:

Straight-line Braking Testing

• Involves measuring the distance it takes for a vehicle to come to a complete stop from a specific initial speed while applying the brakes in a straight line.
• Provides an indication of the vehicle’s overall braking efficiency and effectiveness.

 

ABS (Anti-lock Braking System) Testing

• Evaluates the performance of the ABS by measuring the stopping distance and stability of a vehicle under hard braking while the ABS modulates brake pressure to prevent wheel lock-up.
• Tests are conducted on dry, wet, or slippery surfaces to assess the ABS’s ability to maintain steering control during emergency braking.

 

Brake Fade Testing

• Measures the change in braking performance over a series of repeated brake applications to assess the brakes’ resistance to fade caused by overheating.
• Helps ensure that the braking system maintains consistent performance under prolonged or heavy braking.

Brake Balance Testing

• Assesses the distribution of braking force between the front and rear axles to ensure balanced and stable braking, preventing skidding or loss of control.

 

Hill Start Testing

• Evaluates a vehicle’s ability to hold its position on an incline without rolling backward when transitioning from brake pedal to accelerator pedal.

 

Brake Dynamometer Testing

• Conducted using a brake dynamometer, which simulates road conditions and applies specific loads to the brakes to measure their performance, efficiency, and wear.

Brake System Integrity Testing

• Involves testing the entire braking system, including master cylinders, brake lines, hoses, and hydraulic components, to identify leaks, pressure loss, and system integrity.

 

Handbrake or Parking Brake Testing

• Measures the efficiency of the handbrake or parking brake system in holding the vehicle stationary on an incline.

 

Brake System Inspection and Measurement

• Involves visual inspections and measurements of brake components, including brake pads, rotors, drums, callipers, and brake fluid levels, to ensure proper condition and function.
