What to Do When the Car Brake Pedal Is Hard to Press?
1 Answers
Detailed reasons and solutions for a hard-to-press brake pedal are as follows: 1. Related to pressing the brake before engine shutdown. The car's braking system operates at its maximum efficiency when the engine is running. When the engine is off, the brake booster pump becomes ineffective, and typically, pressing the brake pedal three times will deplete its remaining vacuum. Solution: Restart the engine. Once the engine is running, the brake booster pump will resume functioning, and the brake pedal will return to normal. 2. Leakage or malfunction of the car's brake booster pump. If you haven't pressed the brake pedal after the engine is off, or if you notice the brake pedal is hard to press while driving, it is likely due to a vacuum tube leak or blockage in the brake booster pump. Solution: If this issue is noticed before driving, take the car to a repair shop immediately for inspection. If it occurs while driving, the priority is to slow down and stop the vehicle. Try pressing the pedal multiple times to see if braking can be restored.
