Would it be possible if designed right and using the
right materials, to fit a brake calliper over the rear wheel
sprocket to aid rear wheel braking.

Most things are possible, practical is another question altogether.

If available brake force is the problem I'd direct my efforts to the
front brake. Dicking around with the rear is a waste of time and money.

If it's a question of confidence "Oooh, don't want to lock up the front
'cos I'm a girly pansy foo foo" I'd go out and practice. Or buy a car.

I would agree with you for road use but The bike in question is one I use
over in a large quarry and I was thinking of shareing the load out on the
back
wheel a bit more.

I will ignor this coment. Say it again though and I'll scratch your eyes and
hit
you with my hand bag :-)

I ride a '79 Beamish Suzuki Trials and a '91 Fantic 307 Trials .. the
Suzuki doesn't have brakes, or it does, but not so's you'd notice, the
Fantic can stop on a sixpence. The Suzuki is easier to ride 'on the brake'
but the Fantic locks up rear (and front) at will with very little effort.
It's almost impossible to feather the brakes, they seem either on or off (I
suspect a change of pads might help me with that), but I still mostly use
front.

Rear brake is only really used on very steep downhills, when it's just as
good locked, for balancing, or for sliding round obstacles and skids, it
doesn't really slow the bike much, the front does that, whatever the
conditions.

As my bit above suggests, I agree with Sweller ...

That is the reason I asked. I use the bike in a quarry and I wondered
if adding a second calliper would be possible to share the stresses involved
out a bit.

I use our bikes in quarries too. When you're riding competently, rear
brakes do do a surprising amount of work, but they don't slow you down much,
they just help balance the bike while the front slows it.

Whatever braking force you add at the rear will be negated by the lack of
grip. So long as the back wheel can lock, you don't really need anymore
force. If it can't lock, then there's a serious problem with the brake, and
you need to fix that before adding anything.

IMHO.

You'd have a problem with the chain lube getting on the pads.

<sigh> There's a bike with a sprocket caliper in just about every single
issue of BSH. Chop chains aren't lubed, they're /polished/.
