Where Does Brake Fluid Leakage Typically Occur?
2 Answers
Brake fluid usually leaks at the connection points between the brake pump and the pipelines or the brake handle. The causes and solutions for brake fluid leakage are as follows: Causes of leakage: Brake hose rupture; damaged sealing ring; loose or damaged hose screws. Solutions: Replace with a new sealing ring; if the hose screws are loose, simply tighten them. Function of brake fluid: Brake fluid not only transmits energy but also has anti-corrosion, anti-rust, and lubrication effects, making it an essential part of the braking system. Automotive brake fluid is the liquid used in hydraulic braking systems. It must not undergo chemical reactions, be unaffected by high temperatures, and must not cause corrosion, softening, or expansion to metals and rubber.
I once experienced a brake fluid leak while driving myself. The fluid drips were mainly on the inner side of the wheels and underneath the chassis, especially leaving yellowish wet stains on the garage floor when parked. That time it was due to a cracked aging brake hose, and the leaking fluid made the brake pedal feel increasingly soft, almost causing an accident. Later, when I inspected it, I found that the location of the fluid drips helps pinpoint the leak source, such as common spots like pipe connections or near the master cylinder. Remember, a fluid leak is no small matter—it can rapidly degrade braking performance. You must immediately go to a repair shop to replace the faulty parts and top up the fluid. A quick glance at the ground for oil stains before daily driving can prevent major trouble.
