The rear brake pads of the Changan Eado should be replaced when the wear reaches a visible thickness of 3mm. Below is additional information: 1. The brake pads are equipped with a warning sensor. When the brake pads become too thin, the sensor will trigger an alert on the dashboard. 2. Brake pads, also known as brake linings, are the most critical safety components in a car's braking system. The effectiveness of braking largely depends on the brake pads, making them the guardian of both the driver and the vehicle. 3. Brake pads generally consist of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, with the coating process monitored by an SMT-4 oven temperature tracker to ensure quality by detecting temperature distribution. The heat insulation layer is made of non-conductive materials to provide thermal insulation. The friction block is composed of friction materials and adhesives, which create friction when pressed against the brake disc or drum, enabling the vehicle to slow down and stop.

As a long-time owner of the Changan Yidong, I've been driving this car for five years. Based on my experience, there's no one-size-fits-all answer for brake pad replacement intervals. Generally, I check them every 30,000-50,000 kilometers. If you frequently drive in congested urban areas with lots of sudden braking, you might need to replace them every 30,000 km. For highway driving with less wear, they can last 50,000-60,000 km. Once I forgot to check mine and only noticed when I heard squeaking during braking - the pads were severely worn and nearly caused an accident. Brake pad lifespan depends greatly on driving habits: avoiding sudden stops and maintaining smooth driving can extend their life. I recommend regular professional checks of pad thickness - don't wait until it becomes dangerous.

From a repair perspective, the replacement frequency of Changan Eado brake pads varies by driver, but the standard recommendation is to inspect them every 40,000 km. The OEM pads are of medium quality - if you frequently drive on mountain roads or carry heavy loads (accelerating wear), replacement intervals may shorten to 30,000 km; for smooth suburban driving, they can last up to 60,000 km. In my profession, I've seen numerous cases of delayed replacements - symptoms like brake squealing or reduced responsiveness mean immediate replacement is needed. Pad replacement costs just a few hundred yuan, but postponing it may lead to thousand-yuan overhauls. Remember to monthly check your brake response - safety first, don't compromise it to save minor costs.

I always worry most about brake issues when driving, safety comes first. For the Changan Eado, the brake pad replacement interval depends on road conditions and driving frequency—check every 30,000 km for frequent city driving, replace every 40,000-50,000 km for more highway/long-distance use. Once during a mountainous road trip, my pads wore out quickly, and I felt relieved after timely replacement. Delaying maintenance risks longer braking distances or sudden failure—don't wait for accidents to regret. Develop a habit of annual inspections at minimum.
