Reasons for Hard Braking and Ineffective Stopping in Haval H6
2 Answers
Lack of necessary maintenance on the braking system, excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster, contaminated brake fluid or the formation of vapor lock due to mixing different types of brake fluid under heat, leakage in the brake master or wheel cylinders, or air leaks in the air reservoir or pipeline connections can all lead to brake failure. Below are precautions for using the brakes: 1. Avoid emergency braking at high speeds: While sudden braking is acceptable at low speeds in response to emergencies, it should be avoided at high speeds to prevent vehicle skidding or rollover. 2. Gradual braking: On normal road conditions, apply gradual braking by depressing the clutch pedal while releasing the accelerator, shifting to a lower gear, and then lifting the clutch pedal once the speed decreases before pressing the brake pedal until the vehicle stops. 3. Intermittent braking: On long downhill slopes in mountainous areas or situations prone to high temperatures from continuous braking, intermittent braking—alternately pressing and releasing the brake pedal—can effectively prevent the braking system from overheating.
When I was driving my Haval H6, the brakes suddenly became hard and ineffective, which almost gave me a heart attack. The most common cause is brake booster failure. This device operates using engine vacuum, so a faulty vacuum pump or a leaking vacuum hose can make the pedal extremely hard to press. Additionally, aging or leaking brake fluid can lead to insufficient pressure, making the brakes hard and ineffective. Another possibility is excessively worn brake pads or rusted brake discs that haven't been replaced in time. I once encountered this situation on the roadside—I immediately turned on the hazard lights, pulled over, and called a tow truck. I recommend checking the brake fluid reservoir first. If the level is low or the fluid is dirty, replace it promptly and have a mechanic inspect the vacuum system. Don't push your luck in such situations—safety always comes first.
