How does the aging of Air Pressure Brake Hose affect the braking performance?

In the complex system of the car, Air Pressure Brake Hose (air pressure brake hose) is a key component connecting various parts of the braking system. Its status directly affects the safety and braking efficiency of the vehicle. As time goes by, the aging of the brake hose has become an issue that cannot be ignored. It is not only related to the driving experience, but also directly related to the life safety of the driver and passengers.
1. Causes and manifestations of aging
Cause analysis:
Environmental factors: Brake hose materials are prone to oxidation, hardening and embrittlement due to long-term exposure to harsh environments such as high temperature, high humidity, and ultraviolet radiation.
Chemical action: Chemical substances inside the brake system, such as brake fluid or moisture in the air, may corrode the hose material and accelerate the aging process.
Mechanical stress: Frequent braking operations cause the hose to be subjected to continuous mechanical stress, accelerating its fatigue damage.
Performance characteristics:
Appearance changes: cracks, fading, hardening or swelling appear on the surface of the hose.
Deterioration of sealing: Leakage and seepage problems often occur, resulting in insufficient pressure in the brake system.
Loss of elasticity: The hose cannot return to its original shape when under pressure, affecting the efficiency of pressure transmission.
2. Far-reaching impact on braking performance
1. Extended braking response time:
Aged brake hoses increase the resistance of fluid transmission, resulting in a slower response speed of the brake system. In an emergency, This may increase braking distances and the risk of an accident.
2. Weakened braking force:
The air leakage problem makes it impossible for the brake system to maintain sufficient pressure, thereby reducing the braking force. This not only affects the braking effect of the vehicle, but may also cause uneven braking and affect driving stability.
3. Safety hazards are prominent:
Aging brake hoses may suddenly rupture or break, causing the brake system to completely fail. This sudden failure poses a serious threat to driving safety.
The aging phenomenon of Air Pressure Brake Hose is an important problem in the automotive braking system. It not only affects the braking performance, but also directly affects the life safety of the driver and passengers. Therefore, we should attach great importance to the maintenance and care of brake hoses, and ensure the normal operation and driving safety of the brake system through regular inspections, selection of high-quality products, strengthening of protective measures and regular performance testing.
