Hey people, I'm replacing the piston and when I went to start bleeding it brake fluid started to squirt from these rubber sleeves to the point that the rubber on both sides came off. I've done these type of rear shoes before, never happened like that 

 

What am I doing wrong? 

Are the O ring seals on the pistons?

We’re you bleeding it with the drum off?

You're doing it with the drum off and the pistons have popped out of the cylinder.

I don't know. I

There's nothing else in the packaging, I didn't think these came without any other parts. Just open the package and install. 

 

I had my other half pressing the brake while o watched and the rubber sleeves come off a little when the piston is depressed. That doesn't look right 

DOH!!!! rookie fail, I remember now I had to put the drum back. DOH DOH DOH 

Start again dude.

...Bleeding nuisance!
