What causes the poor performance of the Besturn B70 clutch?
2 Answers
The reasons for the poor performance of the Besturn B70 clutch: air in the clutch pipeline system, and dirty clutch fluid with impurities. Air in the clutch pipeline system: Air ingress causes excessive clutch travel and poor return. This type of fault can be self-diagnosed. If the first press of the clutch pedal feels resistance-free with excessive travel, and the pedal rises after repeated presses, it is mostly due to air entering the hydraulic system. In this case, the cause of the air ingress should be identified promptly, and the air in the hydraulic system should be purged. Dirty clutch fluid with impurities: Impurities cause severe internal wear of the clutch master cylinder or blockage of the return oil hole, preventing the clutch from returning. You can open the engine hood to check if the clutch fluid in the reservoir appears black or gray. If discolored, the clutch fluid should be replaced promptly.
The clutch isn't working well, let me explain the common causes. First, the clutch disc is too worn out. After prolonged use, it gets smoothed down, making the pedal feel high or soft when pressed. Second, there's an issue with the hydraulic system. For cars like the Besturn B70, if the clutch fluid is too low or there's air in the system, you'll feel a jerk when shifting gears. Third, the clutch pressure plate is deformed or the springs are loose, causing inadequate pressure, resulting in car shaking or rolling when starting. Fourth, the cables or rods are rusted and stuck, making operation less smooth. Fifth, poor driving habits, such as frequently riding the clutch in traffic jams. It's advisable to check the fluid level, look for any signs of oil leakage, or feel the clutch travel during a test drive. Don't delay; get it checked at a repair shop early to prevent small issues from becoming big ones, affecting driving safety. Minimize riding the clutch, especially in traffic jams, to extend the clutch's lifespan.
