Fixed brake reservoir, got spark, floats set. Set to 7.5⁰

Have the two "bayonet" pipes actually briken off? If not, you can just push them back into the m/c. If it's busted, but thebrakes were previously ok, just need a new reservoir.

 

Ah. See above. You may be able to dig the bits out with the m/c off.

 

Two nipples successfully removed

 

reservoirs are available with...
different distances between those nipples you pulled out and
different inlet positions.
Choose wisely.

 

I found only two sizes for the ones with the servo and little tank by the driver's seat 100mm and 85mm the 85mm looked the same shape as the one in there. I only realised this after I left the van hopefully I have the correct size

 

Always best to measure the distance between your nipples

 

Did you know, that regardless of size, all adult males nipples are 9 inches apart?

 

Dashes off to find tape measure...

 

OMG

 

If whoever towed you managed to do that I’d be having a good check of the other components under the front of the bus.
Ive seen steering rods and steering dampers damaged before from people being careless with straps.

 

Hard to think how they managed it...but reservoirs don't just snap themselves off

The plastic on those does tend to get brittle over the years.

 

Maybe it was the state that broke the camel's back.

Looking under again the steering box thing also looks wet and makes a creek when I turn to the right

 

Is there any oil in it?

 

The new ones are also quite easy to break... well that's what I tell myself anyway. lol
The nipples + a penny sized circle of the base around them will break out of the main reservoir if you're as clumsy as I was.

 

I managed to break one peg off my old one wrestling it off. Also, the upper reservoir started to swell in an alarming fashion when I was doing a modest pressure bleed of the brakes

But they are 40 years old...

 

Do I have to undo those four bolts to check the level

 

No. If you grovel under the bus, you can see the steering filler. Usually red plastic, but may be covered in filth.
