How to Solve a Brake Hose Burst?
2 Answers
Solutions for a burst brake hose are as follows: 1. The first thing to do is to keep pressing the brake pedal and quickly pull over to the side of the road. 2. Then, check if it's still under warranty. If it is, notify the 4S shop for a replacement; if not, it's recommended to go to a nearby repair shop. Possible reasons for a burst brake hose include: 1. Check if the fuel injector is stuck in the closed position. If the fuel injector is stuck while the engine is running and the plunger continues to inject fuel, the pressure the high-pressure fuel pipe can withstand is limited. If it cannot endure this pressure for a long time, the high-pressure fuel pipe will rupture. 2. The fracture of the high-pressure fuel pipe is also related to poor unloading of the fuel outlet valve. If the fuel outlet valve seal or unloading is not good, the residual pressure in the high-pressure fuel pipe is too high or cavities form, which can cause fatigue damage or cracks in the high-pressure fuel pipe. If the engine runs for a long time beyond the fatigue strength of the high-pressure fuel pipe material, the high-pressure fuel pipe will fracture. In such cases, replacing the fuel outlet valve can solve the problem. 3. The fracture of the high-pressure fuel pipe is also related to the quality of the high-pressure fuel pipe and the assembly method when installing it. Especially when assembling the high-pressure pipe, if stress concentration forms at the pipe connection sleeve, it can easily cause the flare end of the pipe to fracture.
Speaking of brake hose rupture, I experienced it once after years of driving - absolutely terrifying. I had just exited the highway when the brake pedal suddenly went soft, nearly causing a rear-end collision. I immediately turned on the hazard lights and pulled over safely. Upon inspection, I found a cracked brake hose under the hood spraying brake fluid everywhere. Never attempt to keep driving - total brake failure is extremely dangerous. I shut off the engine immediately to check if all the fluid had leaked out. Calling a tow truck is the safest option. After being towed to a nearby repair shop, the mechanic replaced the hose, refilled the brake fluid and bled the air from the system. Regular maintenance should include checking hoses for rust and wear, especially on older vehicles after heavy-load driving. Safety first - it's better to spend extra money than risk DIY repairs.
