I have a 2010 manufactured ksp90. The problem is Rear left wheel is half stuck when i move the vehicle after long period of parking ( few hours = a night, even at day times 6 hr parking). Note that i do not apply hand brakes while parking. It makes a humming sound when moving after initial startup. After some time wheel releases. Also at startup when i apply brakes vehicle drifts.even a little press on the paddle gives a lot of brakes. Tried oiling the hand brake cables. Cleaned rear brakes. Didnt solve the issue.
