Clutch pedal won't come back up after pressing

[72Z/28]

Hello guys

my camaro is equipped with TKO tremec 5 speed but not sure about the clutch brand and Throwout bearing that were installed by the previous owner. The car initially had the wilwood master cylinder set up along with the pedal that he ordered from prodigy customs. However, i did not like how the master cylinder was installed so I decided to order the wilwood master cylinder with billet adapter from Keisler that will fit into the clutch hole on the firewall but I ordered the kit without the hydraulic bearing.

So the new master cylinder now in place, yet I received a call from the shop manager telling me that they had bleeded the system but the clutch pedal won't come back up. That is weired because he is saying it could be a weak spring on the clutch fork.


I tend to disagree with him because the clutch was functioning fine 100% and i believe there is still air in the system causing the pedal not to come back up.

Could somebody advise what to look for to resolve this issue?
