What are the reasons for insufficient brake assist in the Changan Benben?
3 Answers
Insufficient brake assist in the Changan Benben may be caused by a damaged brake vacuum pump. It is recommended to go to a 4S store for inspection and repair. The Changan Benben was jointly designed and developed by Changan Automobile Group and the world-renowned Italian automotive design company I.D.E.A. Its styling was personally crafted by world-class automotive designer JUSTYN-NOREK, featuring a dynamic and stylish body that is simple, powerful, and harmoniously unified. Below is an introduction to the Changan Benben: 1. Body dimensions: The Changan Benben has a length of 3525mm, width of 1650mm, height of 1550mm, and a wheelbase of 2365mm, with front and rear track widths of 1400mm and 1385mm respectively. 2. Powertrain: The Benben is equipped with a new 1.3L all-aluminum engine, which delivers strong power and also features a long service life, high power output, low vibration, low noise, low fuel consumption, and low emissions.
I've driven quite a few small cars like the Changan Benben, and insufficient brake assist is a common issue, mainly because the vacuum pump isn't working. That vacuum pump provides assist to the braking system, and if it's worn out or stuck, the assist disappears. The vacuum lines might also leak, like aging hoses or loose connections, leading to insufficient vacuum. There's also the issue of brake fluid—if the level is too low or there's a leak, the pedal can become stiff. The booster itself failing is another risk; after long-term use, seal failure means it can't build pressure. Additionally, if air gets into the system, braking performance drops significantly. I must remind everyone—this issue should never be ignored. Unresponsive brakes are a big deal; if you can't press the pedal at high speed, an accident is imminent. I recommend getting it checked at a repair shop ASAP, starting with the vacuum pump and fluid level. Regular maintenance should include checking the lines—safety first.
Insufficient brake assist is quite a headache in the Changan Benben. I believe the main culprit is a faulty booster, like when the built-in pressure device fails, requiring more effort to press the brake pedal. Leaks in the vacuum system, such as a ruptured hose or blockage, can also deplete the vacuum. Low brake fluid is another common issue, possibly due to a loose cap or a leaking pump, leading to a dry system when the fluid level drops. Sensor problems can also arise, especially in newer models with electronic assist—faulty sensors may falsely indicate assist failure. I recommend owners start with basic checks: pop the hood to inspect vacuum hose connections for obvious leaks and ensure the brake fluid reservoir is at the correct level. If the pedal feels unusually stiff or makes strange noises, stop driving immediately to avoid further damage. Regular brake fluid changes and hose inspections can prevent many issues.
