my bike rear disk brake keeps locking and will not release the disk until i release some fluid out of the brake fluid nipple , i duno what causes it but i notice it when im trying to find neutral when i am starting the bike ... please help
The crap brake fluid these bikes ship with heats up and expands locking the disk. Happens to guys who like the brake adjusted right up close. Completely drain and replace with any dot 4 fluid.
