The suspension system, located between the wheels and the vehicle body, is responsible for supporting the vehicle body and absorbing vibrations, providing optimal ride comfort. After replacing brake pads, check if the brake pedal returns to its normal position. During daily driving, prevent floor mats from sliding under the brake pedal to avoid insufficient braking. Normally, shock absorbers will generate heat during operation; if they don't, it indicates a leak. During daily use, check for vehicle pull during braking, braking effectiveness, and the parking brake (handbrake). When performing vehicle maintenance, the braking system should first be checked for brake fluid, such as for cracked brake lines or leaks. The brake pedal is also a component that requires attention.
If the suspension system makes a "clunking" sound with each up-and-down movement while driving, and the sound intensifies on uneven roads, it indicates a suspension malfunction, possibly due to damaged shock absorbers or broken shock absorber bushings. Brake fluids should not be mixed. Most cars on the market are equipped with two braking systems: a foot-controlled service brake and a hand-controlled parking brake. If the rubber bushings are severely damaged, they must be repaired and replaced along with the shock absorbers.
The suspension system's shock absorbers should generate heat during operation. The suspension system not only affects the car's ride comfort (smoothness) but also other performance aspects such as handling, stability, and traction. This is because the suspension system includes components such as shock absorbers, springs, anti-roll bars, and linkages. Excessive body roll during cornering, especially sharp cornering, indicates damage to the shock absorbers, stabilizer bars, or guiding mechanism components. When changing brake fluid, the old brake fluid must be completely drained; mixing with other fluids is strictly prohibited, and air must not be allowed into the brake fluid. Generally, the wear of brake pads is greatly affected by usage habits. Automatic transmission vehicles wear out brake pads faster than manual transmission vehicles. After approximately 20,000 kilometers, the brake pads should be checked during each maintenance service. This helps better protect the suspension system.
