What Causes Brake Failure on Rainy Days?
1 Answers
Brake failure on rainy days can be attributed to weather conditions: the slippery road surface reduces friction between the tires and the ground, leading to decreased braking effectiveness. The following are vehicle-related causes: 1. Air in the brake lines: Brake fluid is the medium that transmits force in the braking system. If air enters the brake lines, the brake fluid under high pressure will lose some of its effectiveness, resulting in noticeably weaker maximum braking force. To check for air in the brake lines, turn off the engine and pump the brake pedal several times until it becomes firm. Then, hold the pedal down. If it remains firm, the system is normal. If the pedal slowly sinks, it indicates air in the brake system. 2. Long overdue brake fluid replacement: If brake fluid is not replaced in time, it may contain excessive impurities and moisture, which can impair the transmission of braking force. Therefore, brake fluid should be replaced regularly, and it is advisable to have its moisture content tested at a repair facility if possible.
