What are the reasons for sudden failure of car throttle and brakes?

[NolanDella]

The reasons for sudden failure of car throttle and brakes are as follows: 1. Too much debris in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid or mixed use of several types of brake fluid causing air resistance after heating, leakage in the brake master cylinder or wheel cylinder, leakage in the air storage tank or pipeline interface; 2. Improper operation leading to mechanical failure; 3. Severe overload, which increases the vehicle's motion inertia under the effect of gravitational acceleration, directly causing brake failure. Preventive measures: Do not neglect daily maintenance of the brake system. To prevent brake failure, timely maintenance of the braking system and regular inspections are necessary. Frequently check whether the brake shoes are intact, and avoid excessive use of brakes. When going downhill, shift to a low gear and use the engine's braking to control the car's movement, with the foot brake as a supplement. Avoid severe overload to prevent brake failure.
