Please help
My car has a manual transmission.

You will need to check if the clutch master cylinder is supplying pressure to the slave cylinder as it should be. The master cylinder is made of aluminum and the bore gets worn and may not seal on the rubber cups if you tried to rebuild it. I recommend replacing the master cylinder and then bleeding the new one out to see if this helps. Do not forget to check the clutch pedal linkage to see if any linkage is worn or missing plastic bushings.

If you need some assistance with this, feel free to contact a certified mechanics who can diagnose your clutch pedal issue firsthand and make the necessary repairs.
