My 220 has been sitting for a while. I took it out for a wash today and rode it around the yard afterwards. It didn't take long to find out I had no rear brakes. They were working fine last ride. Can you just replace a seal or two, or would it be best to get a new cylinder. Thanks in advance.

What is not working? You need to start inspecting the system instead of just buying a few bills and hope you find the fix by chance.

Agreed. Lots of things to go wrong there - master cylinder, air in the lines, low fluid, etc. I found once that my line coming out of the master cylinder had been cut during a spill, resulting in quite a mess.

I'm 99% sure it's the master cylinder. I'm not getting anything at the bleed valve. I took the cylinder off and looked it over carefully. It doesn't seem to be making the pressure I think it should have. I ordered a rebuild kit today since they wanted like 160+ for a new one. Less than 40 for the kit. That should fix the problem.

Once you get it rebuilt, try to score a pressure bleeder. Makes things go much quicker and easier.

Well I have rear brakes now! Installed the new piston and seals, bled it out about 50 times to be sure to get all the air out. Working great now.
