What is the reason why the BMW ignition brake cannot be pressed down?
1 Answers
BMW ignition brake cannot be pressed down due to problems with the brake hydraulic system, causing excessive pressure; the newly replaced brake discs have not been adjusted, resulting in the inability to press down. Brake hydraulic system failure: The car's vacuum booster pump leaks or malfunctions. The force applied to the brake pedal is amplified by the brake booster pump. If it fails, the brake loses its assist, making it difficult to press down. Newly replaced brake discs: New brake pads require a break-in period of 200 kilometers to achieve optimal braking performance. Therefore, it is recommended to drive cautiously after replacing new brake pads.
