Are Brake Pads Different for Front and Rear?

Automobile brake pads are indeed different for the front and rear. Generally, the front brake pads of a car are larger than the rear ones, and the front and rear brake pads cannot be used interchangeably. The front brake pads wear out faster than the rear ones, so they need to be replaced more frequently. The rear brake pads are more durable. Although the front and rear brake pads are made of the same material, the front brake pads are usually more expensive than the rear ones. The replacement interval for front brake pads is typically between 30,000 to 60,000 kilometers, while the rear brake pads should be replaced every 60,000 to 100,000 kilometers. Car owners should inspect the brake pads every 5,000 kilometers. If the brake pads are thinner than 5mm, they should be replaced promptly to avoid affecting vehicle performance. Brake pad maintenance methods include: high-temperature protection to prevent corrosion of the braking system, cleaning oil stains from brake discs, brake drums, and brake pads, ensuring proper heat dissipation of the brake discs, regular replacement of brake fluid, and periodic checks of the thickness of brake pads or brake shoes.
Last time I got my car serviced, I specifically asked the mechanic, and brake pads do differ between front and rear wheels. The front brake pads are generally larger and thicker because during braking, the vehicle's weight shifts forward, with the front wheels bearing about 70% of the braking force. For my old Passat, the front pads need replacement every 30,000 kilometers or so, while the rear ones can last 50,000 to 60,000 kilometers. However, in rear-wheel-drive vehicles, the rear pads might wear slightly faster. The key is to monitor actual wear - it's best to have the mechanic measure the thickness with calipers during each service. Remember, front and rear brake pad models are different, so never install them backwards.
I totally relate to this! Last month, I just replaced the rear brake pads on my wife's MINI while the front ones were still in good condition. The mechanic used an iron hook to show me - the wear grooves on the front and rear pads were completely different in depth. He said that for hatchbacks, the front wheels bear more load while the rear wheels mainly provide stability, so it's normal for the wear rate to differ by half. However, some cars have rear wheels with electronic parking brakes, and those pads come with sensor wires, making replacement more expensive. Regular inspections are crucial - I only went that day because I heard metal scraping sounds.
