What are the reasons for brake failure in Dongfeng Fengxing T5 Evo?
3 Answers
Here are the specific reasons for brake failure in Dongfeng Fengxing T5 Evo: 1. Severe overloading: When the vehicle is severely overloaded, the increased inertia due to gravity acceleration directly leads to brake failure. 2. Improper operation: Mechanical failure caused by improper operation, such as prolonged downhill driving, can cause brake pads to overheat, brake drums to carbonize, and the braking function to completely fail. 3. Weather factors: In summer, most cars use air conditioning, which can easily increase the engine load and ultimately affect braking performance. 4. Lack of maintenance: Insufficient maintenance of the braking system can result in excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, contaminated brake fluid, or the formation of air resistance when different types of brake fluid are mixed and heated. Additionally, leaks in the brake master cylinder or wheel cylinders, or air leaks in the air reservoir or pipe connections can also cause brake failure.
I just encountered a similar issue and can help analyze the possible causes. Brake failure in the T5 EVO is most likely due to a brake system leak or insufficient hydraulic pressure, as aging or damaged brake lines can cause fluid loss and inadequate pressure. Another possibility is a faulty ABS sensor misreporting the vehicle speed, leading to assist failure. Additionally, severely worn brake pads failing to grip the disc is a common issue. Poor maintenance, such as not changing the brake fluid for a long time, can allow air to enter the system, resulting in a soft and weak brake pedal. I recommend pulling over immediately and not taking any risks, then checking if any warning lights are on. Visit a professional shop as soon as possible to have the entire system checked with a pressure tester to ensure safe driving. Developing a habit of checking fluids and wear every 5,000 kilometers can help prevent such issues.
When driving this car daily, be cautious if you notice anything unusual. Brake failure is usually caused by high-temperature deformation of the brake discs or vacuum booster pump leakage leading to a stiff pedal; it could also be due to electrical short circuits interfering with the signal transmission of the electronic control unit, causing malfunction. Last time I checked myself, I found that the brake fluid had deteriorated due to water contamination, reducing its performance. A simple preventive measure is to visually inspect the wheel hubs monthly for any leakage marks, and don’t ignore unusual noises—get it repaired promptly to avoid bigger troubles. Safety first—stay calm while driving to handle any situation effectively.
