Why does the BYD F3 clutch pedal not return when pressed down?

[McLeila]

BYD F3 clutch pedal not returning when pressed down may be due to the following reasons: 1. Air in the clutch hydraulic system: This causes excessive clutch travel and poor return. The method to diagnose this issue is simple—if you feel little resistance when pressing the clutch and the clutch travel is too large, this is likely the cause. 2. Dirty or contaminated clutch fluid: This leads to severe wear of the clutch master cylinder (piston) or blockage of the return port, preventing the clutch from returning. The diagnostic method is to check the color of the fluid in the clutch fluid reservoir by opening the engine hood.
