Old and DANGEROUS. If u loosten this clamp where im pointing without having the main spring caged as the clamp gets to the loose enough point the 2 halves will seporate in a violent explosion. Be a good experiment for mith busters.

ONLY remove this clamp where im pointing in this pic on the old chambers that facilitate both. This is the service diaphram and it has a spring but its week and far from deadly. The modern 30/36s r designed with only 1 removable clamp, the service diaphram clamp (the safe one).

Here is another m.i.f. Any brass street elbows this vintage remove them for more modern streeelbows they r way more robust. It took very very little force to snap this. This line is pressurized to colapse the main spring if it snaps goin down the road this hub locks up.

Then there r these dirt boots for the pushrods. All prevo with drum brakes drive axle had these if yours r damaged or missing thats a points deduction. U dont see these on trucks. Its one of the many things u only see on prevo. U want to have a special camper this is one of the things that contributes to that. Keep it whole. This piece has its own part number the 30 36s do not include it.

When u buy the chambers from prevo they r a bit more and worth it.
Where im pointing in the pic above, the 2 halves always come clocked correctly, the relationship between the fittings on the side and the mounting studs on rhe end with the pushrod. Others dont clock them. 1 to the good.

The pushrod always comes cut to the perfect length. Others dont, very important. Thats 2

It comes with the correct clevis, others dont. 3 reasons to get them from prevo.
