The lifespan of truck brake hoses is influenced by various factors, generally ranging from 3 to 6 years.
1、 Usage environment
Climate conditions:
In hot areas, high temperatures can accelerate the aging rate of rubber materials in brake hoses. Long term exposure to high temperatures may cause rubber to harden and become brittle, reducing its flexibility and strength. For example, a truck driving in desert areas may have its brake hose life shortened to around 4 years due to high temperatures and dry weather.
In cold regions, low temperatures can make brake hoses harder and less elastic. If subjected to frequent temperature changes, rubber materials are prone to fatigue and cracking. For example, in extremely cold regions, the lifespan of brake hoses may be more affected, possibly around 5 years.
traffic:
Driving on rough and uneven roads, trucks are frequently subjected to vibrations and impacts, which can put additional pressure on brake hoses. Long term vibration may cause damage to the braided layer inside the hose, reducing its pressure resistance. For example, a truck driving in mountainous areas may have its brake hose life shortened to 3 to 4 years due to frequent bumps.
If driving on muddy and dusty roads frequently, brake hoses are prone to erosion by impurities such as sand, stones, and dust. These impurities may wear down the external protective layer of the hose and even enter the interior of the hose, affecting the performance of the brake system. For example, the lifespan of brake hoses for trucks driving near construction sites may be significantly affected.
2、 Usage frequency and load
Mileage: The higher the mileage of the truck, the higher the frequency of use of the brake hose, and the speed of wear and aging will also accelerate. Generally speaking, trucks with higher annual mileage may have a relatively shorter lifespan for brake hoses. For example, a truck that travels over 100000 kilometers per year may need to replace its brake hoses in about 4 years.
Load situation: Heavy duty trucks have higher requirements for brake systems, and brake hoses need to withstand greater pressure. Long term heavy load driving can make brake hoses more prone to fatigue and damage. For example, for trucks that are frequently loaded with goods, the lifespan of brake hoses may be shortened compared to light-duty trucks, and they may need to be inspected and replaced in about 5 years.
3、 Maintenance and upkeep status
Regular inspection: Regularly inspect the appearance of brake hoses for any abnormal conditions such as wear, cracks, bulges, etc., which can promptly detect and handle problems. If minor damage is found on the hose, it can be replaced promptly to avoid further deterioration of the problem. For example, regular inspections can extend the lifespan of brake hoses by about six months to one year.
Cleaning and protection: Keep the brake hose clean and avoid contact with corrosive substances, which can extend its service life. When cleaning trucks, be careful to avoid using high-pressure water guns to directly flush the brake hoses. At the same time, protective covers or coatings can be used to protect brake hoses from external factors. For example, using a protective cover can effectively reduce the wear and aging of brake hoses, extending their lifespan to 5 to 6 years.
