I changed out my master cylinder resivoir with a kit from AB, all went fine till I went to reinstall. I have a metal oring and I am unsure where it goes. The kit came with 2 rubber orings and 2 grommets for the resivoir to sit on. Any assistance would be greatly appreciated. I am hoping the attached pic helps someone assist me. Thanks in advance.

 

ok.. I just do the same for my disco and as long as I remember it goes inside the yellow plastic,, see the pic... first goes one of the o-rings, smallest then
the part that you ask for ...

Now I can't bleed the brakes... Even removed the nipple and nothing comes out... Any ideas?

 

Bleed the lines where they are going into the ABS modulator from the master first, they maybe have emptied when you worked on the master.

Open the line, have someone push the pedal half way down or so, close the line, release the pedal. Repeat for the other line going in. You might not get a firm pedal right away, but it should get enough that you can bleed normally at the wheels.
