How often should brake hoses be replaced?
2 Answers
There is no fixed time for replacing brake hoses; they require regular maintenance and should be replaced by professionals. More information about brake hoses is as follows: 1. Automotive brake hoses, also known as brake lines, are components used in the vehicle's braking system. 2. Brake hoses are classified into two types: flexible hoses and rigid pipes. Brake rigid pipes are mainly made of No. 20 steel and copper pipes, which offer good shaping and heat dissipation. Brake flexible hoses are primarily made of nylon tubes (PA11) and are marked with the CCC certification, being more flexible. 3. The main function of brake hoses: They transmit the braking medium during vehicle braking, ensuring that the braking force is transferred to the brake shoes or calipers to generate braking force.
A while ago, I just checked my brake hoses and realized this isn't just about time. Rubber hoses are most prone to issues—generally, they need inspection after 4-5 years or 70,000-80,000 km, especially in humid southern areas where aging accelerates. I've seen cases where owners didn't replace them for six years, leading to bulging hoses, fluid leaks, and complete brake failure. During routine maintenance, have the mechanic check hose flexibility and look for leaks at connections. Metal lines don’t need frequent replacement but require rust prevention. If you've modified brakes or frequently drive mountain roads, consider replacing them as early as three years. Safety first—when replacing, it's best to flush with fresh brake fluid too; don’t cut corners on this.
