Rear Master Cylinder

1984 ZG1300A. Rear brake master cylinder is beyond rebuilding - too corroded. Can anyone recommend a suitable replacement cylinder that I can mount inrplace of the original, even if some modification is required? I rarely use the rear brakes, and even then very lightly, so do not need to apply anywhere near the original pressure to the rear caliper cylinders.

One of the guys on the English site did a mod quite recently z1300.co.uk i will see if i can find a link

Hi Harry,

This is the conversion I carried out to my master cylinder.

Thanks Martin.
I wondered about the rear brake light - did you add a pressure switch in the line, or did you find a cylinder with a switch built in.
Also, how did you go with the mounting holes. Did you have to make a bracket to mount it ?
A pic of the back of the assembly would be good if you had one.

Just in case, you can press a new sleeve in. I had it done on the front master cylinder with a stainless sleeve. Works great and lasts forever. Cost was about $100.

Hi Harry,

I was going to fit a pressure switch but the MOT tester didn’t pick it up on the test. Apparently it was only mandatory to have the brake light operated from the rear brake after a certain year. I made some brackets from flat bar to fit the master cylinder to the existing fixings. Sorry no pictures I’m afraid.
