N16 manual car issues

[Prabhath Jayarathne]

Recently, I purchased a 2002 N16 1.3 cc car, and I have observed two issues:

When I travel long distances, shifting gears becomes more difficult, and it feels like the clutch pedal moves without any pressure.

A humming sound occurs when I drive straight. When turning right, the sound gradually fades away.

Can anyone advise me on these issues?

if the clutch pedal is having a loss of pressure it could be the clutch master pump is losing pressure, it can be due to something as simple as leaking seals which can be rectified with a new kit or might need a new pump, best check it with a good mechanic
