How to Adjust Soft Brakes on Wuling Hongguang?
3 Answers
Wuling Hongguang soft brake adjustment method is: 1. There is a small piston in the vacuum bag with a screw on it. Slightly adjust it outward, but not too much, as excessive adjustment may cause brake locking; 2. Check for any brake fluid leakage. If there is leakage, timely repair is needed. If there is no leakage, the issue lies with the master cylinder, which requires replacement. The Wuling Hongguang is launched by SAIC-GM-Wuling Automobile. Taking the Wuling Hongguang S as an example, its body length is 4390mm, width is 1660mm, height is 1750mm, and the wheelbase is 2720mm. The Wuling Hongguang S can reach a maximum speed of 155 kilometers per hour, and the fuel tank capacity is 50 liters.
I run an auto repair shop and often hear Wuling Hongguang owners complain about soft brakes. This is usually due to air bubbles in the brake fluid, insufficient brake fluid, or worn-out brake pads, causing a spongy feel when pressing the pedal. My usual approach is to first check the brake fluid reservoir level, ensuring it's between the min and max lines—if it's too low, I top it up with standard brake fluid. Then, bleeding the brakes is key. Get a partner: you sit in the driver's seat and pump the brake pedal a few times (press down fully and release), while I open the bleeder screw on the brake caliper near the wheel to let the air escape. Once the fluid flows smoothly, I tighten the screw—just be careful not to let the fluid splash everywhere. Afterward, a test drive is necessary: drive slowly and gently brake to check if the response feels firmer. If not, it might be an issue with the brake discs or drums, requiring professional tools for diagnosis. I generally recommend changing the brake fluid every two years to prevent moisture contamination and air bubbles—it’s both convenient and safer. Soft brakes on steep slopes are a big no-no, as they can easily lead to accidents.
I've been driving this Wuling Hongguang for over five years and have encountered soft brakes a few times, solving the issue myself. First, I park the car on level ground and turn off the engine, then open the hood to check the brake fluid reservoir. If the fluid level is low, I top it up with the same type, making sure not to mix different brands. The key step is bleeding the air. Since it's a bit inconvenient to do alone, I ask a family member to help. They sit in the car and repeatedly press the brake pedal while I loosen the bleeder valve near the wheel with a wrench. I wait until all the bubbles are gone and clear fluid flows out before tightening it back. During the process, I'm extra careful to avoid splashing fluid into my eyes or on my hands—wearing gloves and goggles is safer. After finishing, I feel reassured when the brake pedal travel becomes shorter. If the effect doesn't last, I check the brake pad wear. Wuling parts aren't expensive, so I try replacing the pads if needed. During regular maintenance, I often clean the brake wheels to prevent dust buildup, which can affect sensitivity.
