What to Do When the Brake Pedal Is Hard and Difficult to Press?
2 Answers
Here are the solutions for a hard and difficult-to-press brake pedal: 1. Try restarting the engine and press the brake pedal firmly. After starting, the brake should return to normal. 2. If the brake does not return to normal after several attempts, find a nearby repair shop to resolve the issue before continuing to drive. Below is some related information about brakes: 1. During low-speed driving, emergency braking can be applied by pressing the brake pedal firmly if there is a sudden event ahead. However, this should not be done at high speeds to avoid vehicle skidding or rollover. 2. For normal road conditions, gradual braking is recommended. Press the clutch pedal while releasing the accelerator pedal, shift to a lower gear, and once the speed decreases, release the clutch pedal and press the brake pedal until the vehicle stops. 3. On long downhill slopes in mountainous areas or during continuous braking, which can generate high temperatures, intermittent braking—alternately pressing and releasing the brake pedal—can effectively prevent the braking system from overheating.
A stiff brake pedal is truly a dangerous sign. I've encountered this issue several times. Most often, it's due to a malfunction in the brake booster system, particularly a vacuum hose leak or booster pump failure, which causes the brake to harden despite your heavy foot. If this happens while driving, immediately pull over safely, turn off the engine, and restart it—the brake booster should soften again once the engine is running. If the pedal remains rock-hard, avoid forcing the car to move, as the risk of losing control is high. I recommend first checking the vacuum hoses in the engine bay for cracks or looseness and briefly inspecting the brake fluid reservoir for low levels or discoloration. If no obvious issues are found, call for a tow truck and take the car to a repair shop—professionals can use specialized tools to test the master cylinder and lines for safety. Regular brake system maintenance can prevent many problems, such as changing the brake fluid annually. Since I started doing this, my car has had fewer breakdowns.
