82 honda 650 front brakes

[vejadude]

Possibly a real pedestrian problem  but my front caliper gets stuck closed at times and Im not sure where to start with it. I have bled the system but the problem reoccurs and I dont cotton to the idea of just using the rear brakes .Should I disassemble the master cylinder first or would the problem more likely reside in the wheel cylinder.?

problem is a stuck piston in the caliper ("wheel cylinder").
but don't work on the braking system yourself if you don't know what you are doing!
