What Causes Brake Fluid Leakage?
2 Answers
Brake fluid leakage can be caused by: 1. Brake hose rupture. 2. Damaged sealing rings. 3. Loose or damaged hose screws. The solutions are: 1. Replace the sealing ring with a new one. 2. If the hose screws are loose, simply tighten them. Relevant information is as follows: 1. 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. 2. Automotive brake fluid is the liquid used in hydraulic braking systems. It must be chemically inert, unaffected by high temperatures, and should not corrode, soften, or expand metals and rubber. Common types include DOT3, DOT4, and DOT5. The volume of brake fluid changes with temperature, so the brake fluid reservoir has a vent hole. Air drawn in through this hole may contain moisture or impurities, which can be absorbed or dissolved by the brake fluid. As a result, brake fluid containing moisture will have a lower boiling point.
As a long-time car enthusiast, I've found that brake fluid leaks most commonly occur due to aging and cracking of the flexible hoses. Rubber components tend to crack and seep fluid after years of wear and tear. Another frequent cause is worn-out master cylinder seals, which allow fluid to slowly leak out. Additionally, wheel cylinder rust and corrosion can lead to direct fluid loss. Frequent driving vibrations accelerate these issues, especially in hot weather when rubber deteriorates faster. When a leak occurs, you'll notice the brake pedal becoming noticeably softer, and in severe cases, it may go all the way to the floor with no braking power - extremely dangerous. I recommend developing the habit of regularly checking the reservoir fluid level; if it's below the minimum mark, it indicates a leak. Also, inspect underneath the chassis for any oil stains. Don't delay if you spot problems - immediately visit a professional repair shop for inspection and part replacement. Moreover, choosing high-quality brake fluid provides better corrosion resistance and extends component life - never skimp by buying cheap fluids. Try to avoid driving through standing water to minimize rust opportunities. With proper overall maintenance, you can drive with peace of mind.
