What are the causes of brake failure in large vehicles?
1 Answers
The cause of brake failure in large vehicles is poor braking performance of the braking system leading to brake malfunction. It can be judged based on the brake pedal travel (commonly referred to as high or low), the soft or hard sensation when stepping on the brake pedal, the stability after pressing the brake pedal, and the increase in pedal height during braking. The related introduction to brake failure is as follows: Actions to take in case of brake failure: Drive into an emergency escape lane, use engine braking, apply the parking brake, and if necessary, use the vehicle body to scrape against roadside obstacles to slow down. When stepping on the brake pedal, it does not feel soft or sink, but the braking effect is poor. This phenomenon indicates a fault in the wheel brake, such as oil on the brake shoes, poor contact, aging friction pads, wear, or uneven wear of the brake drum. Introduction to brake pedal operation: Automobile brake pedal operations are divided into slow braking (i.e., anticipatory braking), emergency braking, combined braking, and intermittent braking. Generally, during slow braking and emergency braking, before the wheels lock up and the vehicle stops, the clutch pedal should be fully depressed to prevent the engine from stalling and to facilitate changing speed again.
