What causes the poor performance of the Besturn B70 clutch?

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.

I suspect the clutch is malfunctioning, which is often related to routine maintenance. First, let's talk about fluid level inspection. The clutch fluid in a Besturn B70 should be between the min and max marks. If it's too low, the pedal may feel lighter and shifting can become rough. Then there's clutch disc wear, which is normal—after tens of thousands of kilometers, it will age and need replacement. In terms of driving habits, avoid prolonged half-clutch engagement, like creeping in first gear during traffic jams, to reduce friction. If the pressure plate or flywheel is warped, it can cause clutch slippage, sluggish starts, or poor uphill performance. It's advisable to have a mechanic inspect the clutch system regularly, at least once a year—don't wait for a breakdown. Also, maintain gentle operation while driving; harsh, abrupt pedal use accelerates wear. When replacing parts, opt for quality branded components for reliability and durability. Proper maintenance ensures smooth driving.

What worries me most about a faulty clutch is the safety hazard. Issues like slipping during start-up or difficulty engaging gears can easily cause stalling at traffic lights or in congested areas, increasing the risk of rear-end collisions. A failing clutch may suddenly fail to engage gears, which is particularly dangerous on slopes or highways. Causes include excessive clutch disc wear, hydraulic fluid leaks, or rusted pedal mechanisms. For sedans like the Besturn B70, if the clutch feels heavy or loose, check the fluid level and external linkages—simply test the lever by hand to see if it sticks. For safety, pull over and call for assistance if abnormalities are detected; never force the car to drive. Develop good habits: always engage the handbrake when parked, and shift gears gently during start-up to reduce impact. Protecting your clutch means protecting yourself and others—never overlook minor issues.
