ABS warranty period varies with specific vehicle models, generally three years. Functions of ABS: Maximize the effectiveness of the brakes, shorten braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing excellent steering control. Avoid severe friction between tires and the ground, reducing tire wear. Working Principle of ABS: During braking, ABS quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that begins to lock up, keeping the braking force constant. If the wheel continues to lock up, the normally closed output solenoid valve is opened, causing the brake pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force. This keeps the braking state always at the optimal point (slip ratio S of 20%), achieving the best braking effect and the highest driving safety.

I've always considered the ABS system crucial, so I specifically inquired about the warranty period when purchasing a car. Most automakers bundle ABS coverage with the basic vehicle warranty, typically around 3 years or 60,000 kilometers. Mainstream brands like Toyota or Honda generally follow this standard, while premium vehicles may extend to 4 or 5 years. My own car, driven for over two years, has had no ABS issues, but the manual reminds regular sensor checks. Post-warranty repairs can be costly, so I recommend thoroughly reviewing the manual or consulting the dealer when new. Never underestimate this system - a failure could mean dangerous loss of braking on slippery roads. A friend's car had its ABS module replaced free under warranty after the warning light appeared. Safety comes first; treat warranties as protection and stay vigilant.

As a car enthusiast, I must say ABS warranty is usually included in the powertrain warranty, typically lasting 3 to 5 years depending on the model. For regular family cars, it's mostly 3 years; German or American cars occasionally offer longer coverage. I remember discussing at car modification shows that the ABS core consists of electronic pumps and sensors, where warranty-period maintenance is crucial - regular brake fluid checks can extend its lifespan. Once out of warranty, DIY repairs may cost hundreds to start. With today's smarter vehicles, I often use mobile apps to monitor system alerts. My advice is not to focus solely on price when purchasing a car - carefully review warranty terms, especially for safety components like ABS which are vital. Make it a habit to get annual inspections - it saves both hassle and money.

After driving for so many years, I pay special attention to brake system safety. Most cars offer a 3-year warranty for ABS, while some brands extend it to 5 years. I recommend checking the owner's manual immediately to confirm the specific duration and coverage. This system is very practical for preventing skidding, but electronic components are prone to aging. If the warning light comes on during the warranty period, get it repaired right away to avoid accidents. After the warranty expires, regularly check the fluid levels to save money and drive with peace of mind.
