What to Do When the Brakes Suddenly Become Hard and Cannot Be Depressed?

[KendraLynn]

Reasons and solutions for brakes suddenly becoming hard and unable to be depressed are as follows: 1. Dead battery: This may be caused by a drained battery due to reasons such as leaving headlights on for a long time or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. 2. Lack of antifreeze: Some car owners add water or low-quality antifreeze, which can result in the entire cooling system freezing in extremely cold winter conditions, leading to a cracked engine, inoperable water pump, failure to start, and damage to other engine components. 3. Wrong gear selection: When starting an automatic transmission vehicle, the gear must be placed in P or N. If it is in R or D, the car will not start. Some manual transmission vehicles also will not start if the clutch is not depressed.
