How to Solve the Brake Lock-up Issue in Wuling Zhiguang?

Water ingress into the braking system causes the brake master cylinder rubber cup to swell due to water soaking, which requires immediate replacement. Insufficient rigidity of the brake disc leads to deformation after frequent braking, making it prone to lock-up. Improper fit of the brake pads can cause them to adhere to the brake drum easily. This issue of adhesion due to oxidation and rust requires determining the appropriate formulation for the brake pads.

I remember once driving a Wuling Sunshine on a rural road when the brakes suddenly locked up, with the wheels completely stuck and unable to move. I quickly pulled over to a safe stop. I tried gently pressing the brake pedal a few times to release the pressure, but it remained stuck. Later, I figured it might have been due to rusted brake caliper pistons or dirty fluid clogging the lines, as the old car lacked maintenance. I slowly drove to a nearby repair shop, where the mechanic replaced the caliper and brake fluid for about 500 yuan. Since then, I’ve learned my lesson—I check the fluid level monthly to ensure the system stays clean. Ignoring locked brakes is dangerous, as it can lead to tire blowouts or loss of control. Never force the car to move; safety comes first. Spending a little on regular brake maintenance is far better than risking an accident on the road. This lesson is especially useful for Wuling owners.

My Wuling Zhiguang experienced brake lock-up last week while driving in the city. When I pressed the brake pedal, the wheels locked completely, which was quite frightening. After stopping safely, a friend suggested gently pumping the pedal a few times, which sometimes helps relieve the issue. Upon inspection, I noticed the brake fluid reservoir was somewhat contaminated, likely the root cause. Later at the repair shop, the mechanic mentioned this is a common problem with Wuling models, especially after 7-8 years of use, as the wheel cylinders tend to accumulate rust. Spending 300 yuan to replace the fluid and perform a basic cleaning fixed the issue. Regular brake system maintenance is crucial, and avoiding muddy roads can help prevent rust. If an accident occurs on the road due to this, the owner bears full responsibility for any rear-end collision, which simply isn't worth it. I recommend checking the brakes during every maintenance service for peace of mind and safety.

When the Wuling Zhiguang's brakes lock up, stop immediately and inspect. Common causes are rust in the wheel cylinder or old brake fluid clogging the lines. In an emergency, gently press the pedal to see if it releases; if not, do not drive and call a tow truck. A complete fix requires going to a repair shop for cleaning or part replacement. Preventive maintenance is crucial—change the brake fluid annually to reduce issues. Ignoring locked brakes can wear tires or create sudden braking risks. As a car owner, I prioritize simple actions to protect myself.
