Why Can't the Brake Pedal Be Depressed in an Automatic Transmission Car?
1 Answers
The reasons why the brake pedal cannot be depressed in an automatic transmission car are as follows: 1. Dead key fob battery: If the car's key fob battery is dead, the car may exhibit symptoms such as failure to start, no response when pressing the brake, or the inability to depress the brake pedal. In this case, simply replacing the key fob battery will resolve the issue. 2. Faulty vacuum booster pump: If the car's vacuum booster pump malfunctions, the brake pedal may become difficult to depress or fail to return after being pressed. It is normal for the brake pedal to become hard to depress after pressing it several times when the car is turned off, as the vacuum booster pump stops working when the engine is off. Continuously pressing the brake pedal releases the remaining vacuum pressure, making the pedal hard to depress. 3. Brake system failure: The causes of brake system failure can be complex. It is best to drive the vehicle to a repair shop or a 4S store for professional inspection and repair.
