What are the contents of the vehicle braking performance test?

Vehicle braking performance tests include: 1. Braking effectiveness: Refers to a vehicle's ability to rapidly reduce speed until coming to a complete stop, which is the most fundamental evaluation indicator of braking performance; 2. Braking heat resistance: Indicates the thermal stability of braking effectiveness during high-speed braking, repeated short-term braking, or continuous braking on long downhill slopes; 3. Braking stability: Refers to a vehicle's directional stability during braking, typically evaluated by its ability to follow a given trajectory, meaning the capability to maintain straight-line or predetermined curved path movement while braking.
The main contents of the service brake performance inspection include: braking distance test, measuring the distance from applying the brake to complete stop to ensure timely stopping in emergencies; brake force distribution check to verify whether the front and rear wheel braking forces are balanced, preventing vehicle deviation or loss of control; brake pad and disc wear inspection, as excessive thinness affects braking efficiency and requires timely replacement; hydraulic system inspection, including brake fluid level, leakage check, and master cylinder operation status; as well as stability tests such as ABS function verification to prevent skidding during braking. To expand, these inspections not only concern safety but also extend the service life of the braking system. I recommend performing them every six months or 10,000 kilometers, combined with routine maintenance like checking the brake pedal feel—moderate firmness indicates normal condition.
Brake performance testing involves several key points: stopping distance is crucial, measuring how quickly the test vehicle can halt; brake force distribution must be even, ensuring balanced wheel braking; brake pad thickness inspection, replacing if wear exceeds limits; checking the hydraulic system for sufficient brake fluid and leaks; stability tests like ABS functionality. As a frequent driver, I believe modified cars require extra attention—don’t just chase aesthetics, safety is paramount. Regular inspections prevent high-speed incidents, saving both money and peace of mind.
