Kubota KX121-3 Servo controls

[Shibolith 212]

Hi there, we have a 2013, KX 121-3 white cab, the slew brake doesn't work properly. When the machine is cold, when you slew left or right, the machine doesn't stop when the slew lever is released. When the machine is warm, slew operation is normal. Do you think this is a slew brake fault, a servo fault or a sticking valve ?

Both directions? When were the filters changed last? What hours?
