IMO it's more to do with the size and number of discs employed, than the number of pots in the caliper.
Oh' FFS
They were never intended to have brakes.
They were never fitted as standard, all you got were "Gentle retardation Devices"
Leave them original, it makes riding interesting
My 1992 GS brakes are completely standard and work fine 
The front end dive pisses me off, but saaaay laa vee

I tend to go along with Proff on this. Yes the brakes on these old bikes are not like modern ones but then we dont have to soften them with expensive anti lock systems. The brakes I have had on my bm's have had at most a braided hose and always work ok. A bit of planning when riding is required but that is part of the experience. You should see the ones on my Austin 7. Foot brake only works the back wheels and the handbrake only does the front. now they really are "interesting". Trouble is so many "younger" riders have only experienced twin, servo, anti lock all dancing brakes and dont think you can ride properly without them.

I agree with this in principal but......... My GSPD is my principal rider and as such spends most of its time on twisty mountain roads being ridden (quickish) for fun. Even in its day (93) the brakes were ordinary. Age brings on diminished eyesight, reflexes, fitness etc so any extra stopping power is welcomed by me. We are also blessed with numerous furry traffic hazards over here 
My concession is that any mods done can be reversed to original specs so as not to devalue the bike. My other airheads are Sunday coffee shop riders at best so there are less demands on their performance and can stay in standard trim.

I ride all sorts of old classics, some with twin discs, some with one, and some with drum brakes But this is what I did to my R80ST...
EBC disc, Pretech custom caliper, fitted with universal EBC pads.

..
the brakes work ok for what they are, don't need more stopping power, per say but a way to make them a bit easier to apply them, if that is possible.

You can see they're EBC pads. The disc is wearing out.
G/S brakes are significantly poorer than those fitted to the later GS.
Old boy rant follows: : don't listen to anyone who says the standard brakes should suffice - they are the simplest way to an early grave. The standard brakes were considered poor in their day and are dreadful by modern standards. You can ride as slow as you like with as much rider care as the best but when some muppet steps off the kerb or drives out of a junction whilst smiling at you, you need all the brakes you can get!!
There are solutions already mentioned on UKGSer if you search, ranging from 6 pots on standard disks (I've got a billet 6 pot on mine)
- Pros: work well
- Cons: expensive £300+
Using a better say 4 pot calliper and making a bracket to using the same disk
- Pros: Cheap
- Cons: Takes more time and effort
Using the existing caliper on a 320mm rotor with a new bracket to space out the difference.
- Pros: Mid price £200
Works well - used on many enduro supermoto conversions
They all make for better brakes

I have twin discs on the R100T with those ATE calipers and thing under the tank. Brakes - sure if you want to slow down but not actually stop, easier to stick your foot into the front wheel
Fair enough they okay if you bimbling around but commute in and out to London every day and it becomes a freaking nightmare My close encounters went from one per month to several a day and I am riding 75% slower now
Will do the reservior on the handlebar conversion first and see if the ageing process slows down on my bald grey forehead

does anyone know or have diagram of this conversion. i have seen an oilhead caliper used but the bracket was hudge and put the caliper very low, level or below the fork tube.

side trac from brakes...power
i have a r80g/s, the bike runs well as tuned but i need more power. i ride two up on this bike with my wife. i have an r100rs that is farkled out and it is fast. i want this power in my g/s.
i know this is been talked about on here..
i have three option.
1. i have a 1979 r100rt motor(50k??) i think last 70hp motor with big valves, ect.. i can use the jugs,heads and carbs and tubes on g/s.
2. i have a 1988 r100rt motor(millage unknown, but specs out) it has 32mm carbs, smaller valves....
3. steinbach kit, 1000cc for use on g/s heads... not sure about low grate gas.
1 and 2 options are fairly cheep as i have the parts. #3 is 1k$
my concerns are the rear drive being low 37:11 @5k rpms 72mph~ and engine smoothness, i know the 1000cc will vibrate more but i will sacrific that for power, but not reliability. another being fuel. (low grade at low to moderate speeds in other countries)
with the 1000cc mod. i will in the future dual-plug
what do you think?? what will yeld me the right kind of power for this bike?

If you want more power and more brakes.........buy another bike!
Probably not what you want to hear but these devices have their limitations, I've learnt to "appreciate" mine for what it is and just cruise and enjoy. It's all to easy to get caught up in bigger, better, faster, more. Now where did I leave the pipe and slippers?
