What Causes a Heavy Clutch in the Sonata?
1 Answers
Sonata clutch heavy reasons are as follows: 1. The return spring tension is too high; replacing it with a spring of lower tension can resolve the issue. 2. The clutch assist cylinder is damaged; check if the assist cylinder is functioning properly, as low-quality assist cylinders are more prone to such problems. 3. Low compressed air pressure; when this fault occurs, priority should be given to checking the compressed air pressure leading to the clutch booster. 4. Insufficient lubrication leading to excessive friction, which can cause the clutch pedal to feel heavy. 5. The release bearing is too tight; if the clearance between the release bearing and the guide sleeve is too small, it will result in excessive friction, naturally making the pedal heavy.
