Rear Master Cylinder

Hi all. I have a 79 KZ1300 and my rear brakes are not working. A rebuild kit looks like it would do the trick. The rubber behind the plate looks worn and is making a sloppy sound. Thing is, I cannot find a rebuild kit anywhere. I see tons of FRONT rebuild kits but none for the rear.

Ideas? Anyone know anywhere to find a kit for the rear? I appreciate the help. If I have to buy a whole new one then that's what I have to do. But I can't find any of those either. -Mike

Master cylinder or caliper?
What rubber? What plate?

Sometimes m/c may be restored to serviceable condition by cleaning and unclogging the relief port and supply port.

Good Fortune!

I'm referring to the mounting plate the mc and foot peg and brake lever are on. The spring/plunger system behind that plate- the backside of the mc. Sorry, I'm handy but no technical mechanic. the rubber looks work and is making a squishy sound when the brake lever is pressed. And fluid leaks out as well. There has to be a rebuild kit for the rear somewhere.

I don't know how much this helps (if any), but the folks at the link below have the seals for the rear master cylinder. See their stock #ZP-43020-1024. Ed

Thanks. I'll look into those. I'm gonna tear the whole thing down and see what looks the worst.
