Do brake pads need to be replaced for both front and rear wheels at the same time?
2 Answers
The brake pads for the front and rear wheels do not need to be replaced simultaneously, as they differ in replacement cycles. Compared to the front brake pads, the rear brake pads have a longer service life. Below are the conditions for replacing car brake pads: 1. Normal conditions: 1. Front brake pads need to be replaced after driving 30,000-50,000 kilometers. 2. Rear brake pads need to be replaced after driving 60,000-100,000 kilometers. 2. Special conditions: 1. Beginners tend to use the brakes more frequently, leading to higher wear. 2. Automatic transmissions consume brake pads more than manual transmissions, as gear shifting in automatic transmissions relies on the accelerator and brake pedals. 3. Vehicles driven mostly in urban areas experience faster brake pad wear compared to those driven on highways, as city driving involves more frequent braking. 4. Heavier vehicles experience greater brake pad wear. When braking to decelerate at the same speed, heavier vehicles have greater inertia, requiring more friction force from the brake pads, resulting in higher wear.
When it comes to braking, I've noticed that the front brake pads wear out much faster because most of the braking force is concentrated on the front wheels, while the rear wheels only provide auxiliary braking. For example, during emergency braking, the weight shifts forward, accelerating the wear of the front pads. So generally, front pads need replacement every 20,000 to 30,000 kilometers, while rear pads can last 60,000 to 70,000 kilometers. There's no need to replace them together unless under special circumstances like a full vehicle refurbishment or abnormal wear. I make it a habit to have the technician measure the thickness with calipers during each maintenance service; if the front pads are thin, replace them, and check the rear pads before deciding. This approach saves money, extends component lifespan, and prevents premature brake disc failure, as discs and pads must be used in matching pairs. Remember, separate maintenance is smarter—don’t let shops trick you into replacing everything.
