How to solve the hard brake problem of Roewe 350?
2 Answers
Turn off the vehicle, use tools to remove the vehicle's brake, and check whether the vehicle's brake lacks brake fluid. Purchase the brake fluid that meets the model specifications and replenish the brake fluid.
I've encountered the issue of a stiff brake pedal on the Roewe 350 several times, and it's usually not a minor problem. If the brake pedal requires excessive force to depress, it may indicate an issue with the vacuum booster system, such as a faulty vacuum pump or a leaking vacuum hose. The vacuum booster relies on the engine's suction to function, and when it fails, the brake pedal becomes stiff, directly affecting braking performance and significantly increasing the risk of danger. I recommend the first step is to stop and inspect: open the engine compartment and listen for any abnormal sounds from the vacuum pump; check along the hoses for any cracks or looseness. Replacing a small vacuum hose yourself might be manageable, but in most cases, it's best to take it to a professional repair shop, as they have the tools to measure vacuum pressure. Never delay fixing this issue, as it can lead to rear-end collisions or loss of control, especially at high speeds. Regular maintenance, such as changing brake fluid and inspecting the booster every two years, can prevent such problems and save you from major headaches.
