1-4 years: adolescence
　　The peak of a car's life is in its first two years of use. With regular maintenance, there is little problem.
　　Fuel pump:
　　By the time the car was more than two years old, the fuel pump was almost ready to be cleaned or replaced.
　　Brake:
　　The car needs a new brake cover after two or three years of use. When a car is sent for repair, the first thing to check is the brake cover, because the brake cover is the first line of defense for driving safety. As a rule of thumb, brake skid should wear out in about two years, although the exact lifetime depends on the driver's habits. If you're the kind of person who likes to pump a lot of oil and slam on the brakes when the crunch comes, you're bound to get a lot more wear and tear on the brake skin and a shorter life.
　　Shock absorber:
　　In three or four years, the car may not run as smoothly as the new car, in this case, you should check the car's shock absorber. The shock absorber is designed to reduce the vibration of the car. It is part of the suspension system.
