What Are the Reasons for Soft Initial Braking and Lack of Braking Force?
2 Answers
Here are the reasons for soft initial braking and lack of braking force: 1. Brake fluid has not been replaced for a long time: Too many impurities or excessive water content can affect force transmission. Brake fluid must be maintained regularly, as it has strong water absorption properties. Service stations also have specialized tools to measure the moisture content in brake fluid. 2. Leakage in the brake master cylinder or brake fluid lines: This prevents sufficient oil pressure from being maintained. 3. The car has undergone modifications: For example, installing oversized tires can lead to insufficient braking torque and weakened braking force. 4. The brake pads are made of material that is too soft: This results in poor high-temperature performance. Standard-compliant brake pads should be used as replacements.
As a veteran driver with over 20 years of experience, I've encountered situations where the initial brake pedal travel feels soft and lacks power. The main reasons are often insufficient brake fluid or air in the system, since the system needs to be airtight to generate pressure. Secondly, severely worn brake pads or calipers not retracting properly can also make the initial pedal travel feel weak and ineffective. I still remember that time on the highway when the brakes didn't respond, nearly causing a collision - later inspection revealed a slight oil leak from the piston in the master cylinder. If you encounter such issues, don't hesitate - immediately check the brake fluid color and level, and ensure regular replacement. The braking system is a matter of life and death - if a car doesn't feel safe to drive, it's better to park it for repairs rather than risk driving it. Make it a habit to get professional inspections every six months - spending a little money can prevent major accidents.
