Is the brake failure issue in Model Y serious?
2 Answers
Brake failure is a significant problem. When a driver needs to brake, brake failure can easily lead to accidents. Causes of car brake failure: 1. Lack of necessary maintenance of the braking system: excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid or mixing different types of brake fluid leading to vapor lock when heated, leakage in the brake master cylinder or wheel cylinder, or leaks in the air reservoir or pipeline connections. 2. Improper operation causing mechanical failure: such as prolonged downhill driving causing the brake pads to overheat, carbonization of the brake drum, and complete loss of braking function. 3. Severe overloading: under the effect of gravitational acceleration, the vehicle's motion inertia increases, directly leading to brake failure.
The braking system design of the Model Y is quite advanced, and I haven't encountered any issues during my regular driving, but there are indeed sporadic cases online. In fact, electric vehicle brakes differ from traditional ones, relying on electronic assistance and regenerative braking working together, which may cause response delays in extreme situations. I've checked the data, and the probability of actual hardware failure is even lower than in gasoline cars, with most issues stemming from system software. It's advisable to test the brakes in an open area after each OTA update, paying special attention to changes in emergency braking distance. Slow down in advance during rainy days because the weight of an electric vehicle can affect braking performance. Regular inspection of brake pad wear is also necessary—don't wait until the warning light comes on to address it.
