How do I disassemble front master cylinder on 84 GS550L

[antlese]

Hey guys,
My front brake lever has no pressure. I replaced the brake fluid and tried bleeding the brake, but no fluid gets pushed out.

So I want to take apart the master cylinder, and clean it up, and replace the innards with a rebuild kit if necessary.

The MC is off the bike. I want to remove the piston, but I am unsure of how to get the dust cover off the piston. Do I just grip it with sone needle nose pliers and pull untill it breaks away (and risk tearing it)?

Or should I just tear it and replace it anyway.

Just wondering if there is a tip or trick to getting the piston and spring out?

Thanks
Antlese

They usually are sealed against the bore from heating up over the years and the rubber is stuck good...will almost always tear.

Need some real long pins on the split ring pliers to reach down in and remove the circlip.

IIRC the process is in the manual.

Maybe this will help
