The reason is a disorder in the brake system circuit. Below is some information about the Song Pro: 1. Features: It is a "global intelligent five-seat SUV" under BYD. Taking the 2021 second-generation 1.5T manual elite model as an example: it uses a 1.5T inline four-cylinder engine with a maximum torque of 245 Nm and a maximum horsepower of 160 hp, equipped with a 6-speed manual transmission, and the body type is a 5-door, 5-seat SUV. 2. Appearance: The length, width, and height are 4650mm, 1860mm, and 1700mm respectively, with a wheelbase of 2712mm, a fuel tank capacity of 63 liters, a front suspension type of MacPherson independent suspension, and a rear suspension type of multi-link independent suspension.

I just experienced a brake failure incident with my Song Pro, which gave me quite a scare. The issue most likely lies with the brake fluid—if it's insufficient or leaking, the pressure drops, making the brakes feel spongy. Additionally, if the brake pads are worn out and not replaced in time, the reduced friction leads to poorer performance. Especially with the Song Pro's system, if the sensors in the electronic power assist fail or the software malfunctions, the brake response can become sluggish or even fail entirely. Upon later inspection, I found that a minor leak due to aging hydraulic lines was the culprit. Fortunately, I got it repaired in time. I recommend that owners regularly check fluid levels and pad thickness during maintenance—don’t wait until an accident happens while driving. Safety comes first. With frequent city commuting, even though the BYD Song Pro is excellent, brake system maintenance shouldn’t be neglected. Fluid and pad replacements should be done every two years.

I've researched the brake failures of the Song Pro several times. Common issues include brake fluid leakage, either due to loose pipeline connections or a damaged fluid reservoir, resulting in insufficient hydraulic pressure. Excessive wear of brake pads is also a critical problem, as the loss of friction material leads to ineffective braking. When the Song Pro's electronic systems, such as the ABS control module, malfunction, the brakes may feel stiff or completely unresponsive. During diagnosis, start with the simpler aspects, such as checking the fluid color and level, and testing the pedal's return condition. If these are normal, then investigate potential sensor or ECU issues. In practice, replacing the fluid or pads can resolve most cases, while more complex situations may require replacing the pump or updating the software. If owners notice any brake abnormalities, they should stop immediately and seek professional repair at a specialized shop, avoiding any risks on the road.

Driving the Song Pro to take kids to school can be dangerous if the brakes fail. The reasons might be simple, such as insufficient brake fluid or worn-out brake pads, which affect normal braking. The electronic components should not be overlooked either—a malfunction in the Song Pro's power assist system can reduce braking sensitivity. For safety, if you notice the brake pedal feels too soft or too hard, pull over immediately and turn on the hazard lights—don't continue driving. During regular , pay close attention to the brake system: check the fluid frequently and replace the pads on time. BYD's maintenance recommendation is to inspect it every 6 months—following this can prevent issues.

The brake failure of the Song Pro may be caused by mechanical or electronic issues. Mechanical aspects: Excessive wear of the brake pads can lead to insufficient braking force, and hydraulic leaks can cause a drop in pressure. Electronic aspects: The Song Pro is equipped with ABS and EBD; sensor malfunctions can misjudge road conditions, and the control unit may incorrectly distribute braking force. Software bugs or untimely ECU updates are also common. During maintenance, use an OBD tool to read fault codes for accurate diagnosis. For prevention, regularly clean the discs and pads, test oil pressure, and keep the system optimized.

My neighbor's Song Pro experienced brake failure, which was found to be due to brake fluid leakage at the joint and severely worn brake pads. There might also have been an issue with the master cylinder, as the pedal wasn't returning quickly. After repairing the hydraulic system and replacing the pads, the problem was resolved. The lesson is not to ignore unusual noises during braking or abnormal pedal behavior; getting an early inspection at the shop can save a lot of trouble. It's recommended to have a comprehensive check at least once a year, especially for frequently used vehicles like the BYD Song Pro, to ensure safe driving.
