Question about 1984 Honda CB 700 SC Nighthawk
Did you take apart and clean the master cylinder. There is a large hole in the reservoir that feeds the fluid to the piston. But there is also a tiny pin hole that allows the dot fluid to return to the reservoir. If this is plugged on brakes it will lock the front wheel. On a clutch it might be what is locking the slave cylinder.If you pull the lever and the clutch does not engage you have air in the line. If you pull the lever and the clutch engages but does not disengage till you open the bleeder screw on the slave cylinder , the pin hole (fluid return hole) in the master cylinder is plugged. Take the master apart and clean it. You can pull the rubber cap that protects the piston out of the master and remove the piston with a circlip pliers. Honda sells a master cylinder rebuild kit and clutch slave o-ring seals if you need them.
