Master cylinder locked up

[Joel]

I can't get my front brake lever to move. Not used to hydraulic brakes on a bike. I guess i had them on my old Goldwing, but sold that long ago. Bought a used M-cylinder online, and i cant budge the hand lever. I've opened it up and looked inside, but dont see anything. Wouldnt have this problem with the old cable brake. grumble, grumble...

'78 xs650 with '80 engine.

Disassemble as much as possible and soak in vinegar. New rebuild kit. Thats about where your at. You can also try to get it freed up by squirting some brake cleaner through the orifices. You should still do a rebuild kit.

Hope theres no pitting...

I'll give it a try. Take a while to get the rebuild kit. Thanks.
