How Often Should Brake Calipers Be Replaced?
2 Answers
Brake calipers should be replaced every 30,000 to 50,000 kilometers. The brake is located below the driver's seat and the console. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transport, or machinery. The lifespan of a brake disc is more than 3 years or 100,000 kilometers. If new brake pads are not properly broken in, they may also produce abnormal noises. Newly replaced brake pads tend to be harder and will improve after approximately 200 kilometers. Some drivers accelerate and brake sharply to quickly break in the brakes. However, this will reduce the service life of the brake pads. It is recommended to observe the situation over a period of time in such cases and avoid artificially forcing the wear of the brake pads. Brake maintenance methods include: high-temperature resistance protection to prevent corrosion of the brake system and avoid brake pads seizing due to high temperatures; cleaning oil stains from brake discs and drums to ensure good heat dissipation; regularly replacing brake fluid; and periodically checking the thickness of brake pads or shoes.
From my experience in auto repair, brake calipers don't have a fixed replacement interval. The main situations requiring replacement are when the caliper piston seizes due to rust causing one-sided braking, brake fluid leakage, or stuck guide pins. During routine maintenance, ask the technician to inspect with a flashlight - check if the dust boot is cracked and whether the piston is leaking. I've seen many vehicles with over 100,000 kilometers still having good calipers - maintenance is key. When replacing brake pads, always clean the caliper slide rails, and changing brake fluid every two years prevents piston corrosion. If you notice the vehicle pulling to one side when braking, strange noises, or increased stopping distance, inspect the caliper immediately. Aftermarket parts cost just 300-500 yuan to replace - much cheaper than dealing with an accident.
