[Healeys] Rear Wheel Cylinder Retainers

[Bob Spidell]

Listers,

I've replaced a few rear wheel cylinders and have always wondered about 
the 'proper' orientation of the two U-shaped plates that retain the 
cylinders. One of the U-shaped plates is flat with a couple notches at 
the 'top' of the U--if it was oriented like the letter--and one has a 
couple 'tangs' on top that hook into the notches to retain the two 
pieces (which are designed to slide against the backplate to enable 
'self-energizing' or servo effect). The piece with the tangs is usually 
slightly bowed and springy--at least, mine are and I don't think I've 
ever bought new--apparently to spring load the two pieces, which 
interlock, but it could have been bent during re/assembly.

My question is, does the notched, flat plate go against the brake 
backplate, or does the curved piece with the tangs go against the 
backplate? It may be that they can only be assembled in place in one 
way, and it seems they would function OK either way, but I've always 
installed them with the tanged, curved piece against the backplate, as 
it seems the cylinder would slide easier that way (I also put a little 
grease on the areas--cylinder and backplate--that slide or are slid 
against).

TIA,
Bob
