Clutch??

I have a 2005 vnl 670 and the issue is when i put it on gear and release the clutch,its hesitating to roll.my cluth is only 4 moths old.after a few seconds of resistance then its fine.anyone please help me out if you have this knoledge.thanks

 

Its a self adjusting clutch

 

Oh gosh.if that is the case do they have to take the transmission down or it can be done without taking it apart

 

I have found the problem.after i disconected the trucktor from the trailer,the trucktor is is not behaving like that.i drove it in the city so i can stop in traffic lights and seems like the problem is on the trailer brakes.after i connected the trailer the problem comes back

 

Wherever i tap the service brakes and then try to roll foward its drugging like the brakes are not completely released then after a few jerks the truck rolls ok.could it be the brakes adjustment on the trailer??

 

If i put the truck in gear without touching the brakes the truck if fine but once i tap the brakes the drugging problem starts
