I replaced the master cylinder and booster this weekend. The replacement parts did not come with a reservoir so I removed the old one and used it. I though for sure I was going to break the reservoir either when removing it or installing it.

Is there some special trick to it? I need to know because the reservoir may be leaking where it goes into the master cylinder. It did not leak before I muscled it in and out.

Instead of "bench" bleeding the master cylinder I installed it on the truck and then connected hose from the ports (using the included plastic adapters) and ran the hose back into the reservoir. I then very slowly used the brake pedal to flush out all the air. This worked out really well.
 
I always just pry them up and out with a screwdriver/ small pry bar.
 
Oddly enough I did use a pry bar and screw driver. It just didn't seem right to do it that way.

When reinstalling the reservoir do you leave the rubber grommets in the master cylinder and the cram the reservoir into them? Or do you pull the grommets out and put them on the reservoir and then put all that into the master cylinder?
 
I've always left the grommets in the master. Lubricate them with a bit of brake fluid and push it together.
