What Causes the Brake Not to Return to Position?

[SanKaleb]

Brake not returning to position is caused by the brake caliper not retracting. Possible factors leading to this issue are as follows: 1. Air in the brake fluid line. Brake fluid serves as the transmission medium in the braking system. If there is air in the fluid line, the brake fluid under high pressure will lack sufficient force, resulting in noticeably weakened braking power despite still functioning. In such cases, it is essential to promptly visit a repair shop for a brake system bleeding procedure. 2. Brake fluid not replaced for an extended period. Brake fluid has strong hydrophilic properties and easily absorbs moisture from the air. If not replaced in time, it will contain excessive impurities and moisture, which can hinder the transmission of braking force. 3. Oil leakage or overly soft brake materials. Generally, oil leakage from the master cylinder or brake fluid line will cause the vehicle's brakes to feel soft. Additionally, if the brake materials are too soft, their high-temperature stability will deteriorate, similarly leading to soft brakes in the vehicle.
