1 Answers
The methods to restore extended brake pedal travel are as follows: 1. First check if the brake pads are excessively worn: Generally, mid-to-high-end cars are equipped with brake pad wear warning functions. Once the brake pads approach the critical wear level, the corresponding warning light will illuminate on the dashboard. The brake master cylinder contains several rubber cups that squeeze brake fluid through the brake pedal, transmitting the force to the wheel cylinders, which then push the brake pads to create friction against the brake discs for braking force. 2. Check for internal leaks in the brake master cylinder and wheel cylinders. 3. Start the car and wait for the idle speed to stabilize (approximately 2-3 minutes). 4. Press the brake pedal firmly all the way down. 5. After two seconds, pull up the handbrake while keeping the foot brake firmly pressed for several seconds. 6. Then slowly release the foot brake, and finally release the handbrake.
