What Causes Soft Brakes in Mercedes-Benz?
1 Answers
Causes of soft brakes in vehicles are as follows: Air in the brake lines: Brake fluid is the medium for transmitting force in the braking system. If air enters the brake lines, the brake fluid under high pressure will appear insufficient in strength. Although there is still braking force, the maximum braking force is significantly weakened. In this case, the braking system should be promptly bled at a repair facility. The method to determine if there is air in the brake lines is to press the brake pedal several times with the engine off until the brakes become firm, then hold the pedal down. If it remains firm, it indicates normal conditions; if the pedal slowly sinks, it means air has entered the brake system. Brake fluid not replaced for a long time: If the brake fluid is not replaced in time, it will contain excessive impurities and moisture, which will affect the transmission of braking force. Therefore, brake fluid must be replaced regularly, and it is advisable to conduct a moisture content test at a repair facility when possible. Oil leakage or overly soft brake materials: Generally, oil leakage from the brake master cylinder or brake lines will cause the vehicle's brakes to become soft. If the brake material is too soft, high-temperature stability will deteriorate, which will also result in soft brakes.
