What to Do When the Brake Pedal of an Automatic Transmission Car Won't Depress?
2 Answers
Reasons why the brake pedal of an automatic transmission car won't depress: 1. Dead key fob battery: If the car's key fob battery is dead, the car may not start, and the brake pedal may not respond or won't depress. 2. Brake system malfunction. 3. Faulty vacuum booster pump: If the car's vacuum booster pump fails, the brake pedal may not depress or may not return after being pressed. 4. Obstruction on the brake pedal: When wearing high heels, it's easy for the shoe sole to get stuck on the brake pedal. Solutions are as follows: 1. Replace the key fob battery. 2. Take the vehicle to a repair shop or 4S store for professional inspection and repair. 3. For safety, it's advisable to wear flat shoes while driving.
That morning when I went to drive, I found the brake pedal was stiff, and my heart sank. Later, I learned that the brake assist in an automatic car disappears after the engine is turned off, especially if the steering wheel isn’t straightened when parked. First, you need to check if the engine is running—if not, stepping on the brake will naturally be harder. If the engine is running but the brake still feels rock-hard, it’s likely an issue with the brake booster pump. Once, I experienced a vacuum hose leak, and the pedal felt like a brick. Quickly check if the brake fluid is sufficient and if there are any leaks in the lines—this is no small matter. Also, don’t forget the possibility of stuck brake pads, especially after rain when the rear wheels can rust and seize. Brake issues are nothing to take lightly; I always call a tow truck to take it straight to the repair shop—risking a breakdown on the road is unthinkable.
