This might help. It is from an article I wrote a few years back

1. Apply Girling mechanical grease sparingly to the
backplate and wheel cylinder surfaces where they will subsequently
mate.

2. Fit the wheel cylinder into the backplate from
the brake drum side. It may be necessary to temporarily remove the
bleed screw as it may not go though the backplate aperture. Replace
this screw from the outside.

3. Fit the smaller of the two retaining clips with
the lugs outermost and in the direction from where
the brake lever will later be fitted.

4. Fit the brake lever from the same side as the cylinder
through the slot, slipping it under the cylinder body. Tip - In use
the brake lever cross pin rotates on the relatively soft backplate.
This can wear a hollow in the backplate which if deep can cause problems
with centralising the brake shoes in the brake drum. It may be necessary
to have this area built up with welding and grinding back to a flat
surface. In any event plenty of Brake metal grease would not go amiss.

5. Slip the larger clip into the slot in the wheel
cylinder over the top of the smaller clip and towards the handbrake
lever until the protrusions on one clip fit into the two slots on
the other. When this is achieved the clips will lock together.

6. Finally fit the rubber boot carefully easing its
inner lip under the rim of the larger clip.

It is worth checking that the boot is still correctly
located when the shoes and drums have been fitted and the adjuster
turned to the point where the correct adjustment has been made.

Removing a wheel cylinder is the reverse of the above
but care will have to taken when the two clips are prised apart in
order to clear the locking protrusions as the rubber boot can easily
be damaged with a sharp instrument.
