It is possible I believe, but you may not want to do such a thing.  Most braking setups involve the brake balance having the greater braking capacity on the front, with the weaker braking capacity on the rear.  Otherwise you could very easily end up in a situation where the rear wheels lock up as the weight transfers to the front, with the result of the back end wanting to slide out from your control.

Which is still controllable...

What you don't want is the fronts to lock, because if they do then you loose steering and breaking power.

9/10 you want more braking power at the front which gives you greater stopping power, but not as much control. By having bigger brakes on the rear your stopping power isn't as great, but you have far more control over the car while braking.

I think you may have over looked one small point and that is the 11" front brakes are twin leading shoe, which means that the two pistons push out the shoes in the same direction, where as the 10" brakes a single leading shoe which means that the shoes push out in opposite directions.  So my point is that how would you stop the vehicle when you are reversing if you fitted 11" brakes all round.

The LWB's have 11" brakes front and rear. Twin leading shoe on the front, single leading shoe on the rear.
Yes they don't work as well going backwards but you don't go 60 mph in reverse..........do you??
I had them on my SWB and didn't have any balance probs.

also need to make sure that the front to rear brake bias isnt screwed up - u might need to retain the original size cylinders

Can I ask why. This may be a silly question. I have 11" fronts and 10" rear on my 88" With a 90 servo and master cylinder. The brakes are brilliant. If they go out of adjustment they are well lets say ****. A well set up set of brakes are ok....you may have problems elswhere if they are not working well. I spent weeks scratching my head why my brakes did not work well then one day I took them off to find the drums was so worn that the shoes did not sit true. A set of drums on the front made my brakes fantastic...... Wish you lived closer and you could have had a drive.

Properly set-up and maintained, the 10-inchers are fine.  It's a bit like the std/parobolic spring argument - replace something worn out with something different thats perfectly set up and theres bound to be a massive improvement - the assumption is that it's all down to the different kit, not the fact that it's all new & properly set up.

(And no - I'm not saying it's not worth it, just that the difference may not be worth the trouble. Now upgrading to discs....)
