Now I've removed the service brake clamp and with a tap the 2 pieces seporate and the diaphragm comes out.
In the photo I've turned the slack adjuster back to release the service brake sprint so u can see it.
Nother good tip. If u don't hold the spring down by backing the slack out first u r faced with trying to push it back during diaphragm instalation and it's much more difficult. When u push on this plunger u r not just compressing IT'S spring u r also having to overcome the springs that hold the brake shoes to the rollers. It's doable but unnessessary, do it my way.

Now here is the emergency half opened up, again these r the old style very dangerous I'm showing this because I thought u might want to see and I know what I'm doing.
If u zoom in the middle u can see how the cage tool locks in from the back side.

Here is the emergency half open with the diaphragm no longer present and I backed the cage bolt out as far as I could so that main spring is exposed.
