What Causes the Brake Pedal to Slowly Sink Due to ABS?
1 Answers
Brake system leakage or air entering the brake system. Below are the relevant details: 1. Brake system working principle: It uses brake fluid to transmit pressure to the brake calipers (wheel cylinders), achieving braking on all four wheels. When the brake system leaks, air can enter the system. Additionally, failing to follow the proper bleeding procedure when replacing brake fluid can leave residual air inside the system. 2. Other reasons for the brake pedal slowly sinking: Brake caliper (wheel cylinder) corrosion causing poor retraction, excessive gap between brake pads and discs, and wear of the master cylinder piston—all these issues can lead to the brake pedal slowly sinking.
