What are the reasons for the decrease in brake fluid?
2 Answers
There are several reasons for the decrease in brake fluid: 1. Wear: If the brake pads are worn, the brake fluid will replenish the pipeline, causing the fluid level to drop. Friction between metal parts inevitably leads to wear, and both the brake pads and discs are consumable parts that will become thinner with use. 2. Leakage: If there is a leak in the brake fluid pipeline, it is recommended to inspect and repair it promptly. If the fluid level is found to be low after inspection, it is advisable to first check the brake pads and then the brake discs. After replacement, the fluid level will usually rise. It is best to check the brake fluid level regularly every month, paying attention to whether there is a significant drop in the fluid level or a deterioration in quality. If so, the brake fluid should be added or replaced promptly.
In my over ten years of driving, one of the most common issues I've encountered is the decrease in brake fluid levels, usually due to system leaks. Aging or cracked brake lines, as well as damaged caliper seals, can cause the fluid to leak. Additionally, when brake pads wear out, the pistons extend further, requiring more fluid, which naturally lowers the fluid level. If not addressed promptly, the brake pedal may feel spongy, and the braking distance increases—a significant safety hazard. During routine maintenance, I regularly check the fluid reservoir. If I notice the level is low, I immediately take it to a professional shop for inspection to ensure travel safety isn't compromised. Some often overlook factors like fluid evaporation or loss due to thermal expansion, which is more common in hot weather. In short, staying vigilant is key. Have a technician inspect the brake system during every service to prevent minor issues from becoming major problems.
