How often should the brake discs of the Baojun 510 be replaced?
4 Answers
The front brake discs of the Baojun 510 should be replaced approximately every 30,000-50,000 kilometers, while the rear brake discs can be replaced after driving about 60,000-100,000 kilometers. Below is an introduction to brake discs: Function of brake discs: A brake disc is a circular disc that rotates along with the car when it is moving. It works together with the brake caliper and brake pads. When the brake is applied, the brake caliper and brake pads clamp onto the brake disc to slow down or stop the vehicle. Classification of brake discs: Brake discs can be structurally divided into solid brake discs and ventilated discs. A solid brake disc is simply a metal disc used for braking, without any special construction. Ventilated discs come in two forms: slotted discs and drilled discs. Both designs aim to improve the cooling performance of the brake disc, reduce thermal fade, and provide better braking capability.
I've driven compact SUVs like the Baojun 510 for many years, and there's no fixed time for brake disc replacement. It mainly depends on your driving habits and road conditions. If you're often stuck in city traffic with frequent braking, the brake pads wear out faster, and the discs follow suit. On long highway trips where you rarely brake, they can last up to 80,000 kilometers. The Baojun 510's brake discs come with an initial thickness of around 20+ millimeters. During each maintenance check, I ask the mechanic to measure them—if they're down to less than 15mm, it's time for a replacement. Other warning signs include unusual braking noises or steering wheel vibrations while driving. I recommend inspecting the disc surfaces every 30,000–40,000 kilometers; if you spot deep grooves or cracks, address them promptly—don't wait for a critical failure. Cultivate the habit of anticipating stops early to avoid harsh braking—it saves money and extends lifespan. Safety first: with cars, I’ve learned it’s better to over-maintain than cut corners. That’s my hard-earned lesson.
As a Baojun 510 owner who just bought the car two months ago, I'm mainly concerned about when I can save money on repairs. Replacing brake discs isn't cheap—it costs over a thousand yuan—but the manual says to check them only after reaching 100,000 kilometers. Honestly, there's no need to stick strictly to the timeline. I mainly drive to and from work with few traffic lights, and by paying attention to avoid heavy braking, the wear is slower. I usually check the disc surface when washing the car; if it's heavily scratched, it's time to prepare for a replacement. For maintenance, it's best to go to the 4S shop—they offer free thickness inspections. If you often drive on gravel roads in rural areas, I recommend checking every 60,000 kilometers—safety should never be taken lightly. A friend of mine neglected to replace his and almost had an accident due to brake failure. Light braking in daily driving saves both the discs and fuel—a habit especially useful for beginners.
I worked as a car mechanic for several years and encountered many Baojun 510 owners asking about brake disc issues. In fact, the lifespan depends on wear level—generally replace when thickness reduces below 20% (original specification around 20mm). Measure precisely with calipers during each maintenance. Common problems include grooved surfaces, cracks, or edge fractures. Driving habits greatly influence longevity—frequent city stop-and-go may wear them out in 40-50k km, while smooth highway driving can last over 100k km. Recommend replacing brake pads simultaneously for time efficiency and cost-effectiveness. Immediately inspect if noticing longer braking distance or vibration. Safety is no trivial matter—professional operation ensures security.
