New 69/70 1000 ut owner from South Africa

Good morning from a chillly winters day in South Africa
 
I recently (yesterday) purchased a 69/70 model Datsun 1000 ute. Now in SA, as far as i know, this is not a common model we got, so parts may be a bit difficult to source and importing is not an option with our eceonomy and exchange rate.
 
We have alot of older1200s and the Nissan 1400 ute was sold here until mid to late 2000s as a Nissan 1400 Champ so spares are in abundance for that model.
 
Would some of the spares be interchangeable? Specifically braking system, my 1000s brakes are almost non existent, pedal is almost on the floor and pulls violently to one side on hard braking. Im assuming brake cylinder kits are needed due to age and most likely worn out. Also the handbrake does not work at all, not sure if the cable is broken or if the cyclinders are worn out. 
 
Any info would be appreciated. I have not had much time to research as yet but i thought id ask on here and see.
 
Thanks everyone.
recondition and reline your braking components, there should be plenty of shops that can do it there since Johannesburg should still reline many truck brakes etc.

The standard drums are good but if you go for more power it is good to at least upgrade your brake master cylinder for a little more pressure.

The 1k race cars campaigned worldwide in rallye and circuit racing used a brand called green grabber shoes for extra bite on the drums.

The more clever use early 65-68 bluebird or 68-78 620 front and rear drums and throw away the cast iron drums and use the 260z finned alloy drums all round and brake shoes fit from all later 620, 720, 310, 810, 910 cars.

All mechanicals interchange just panels and brakes from 1200 ute can be made to work also for the front with some access to a workshop turning machine.

I believe the early datsun 1200 models with drum brakes at all wheels have the same brakes as a datsun 1000.
 
For the rear I believe there are two slave cylinder diameters, one for drums all round and another for use with front disc/rear drum brakes, the difference in slave diameter is to set brake bias for the differing systems.
Either size will work in the diff, so if only one size is avaliable then just run what you can get your hands on if you are looking to buy a relpacment part.
 
For a 1200 with drums all round youll be looking at the earliest models, from the early 70's  and not later versions, so if your parts store doesnt have a listing see if there is an earlier option to select.
 
But as D has suggested,most brake shops should be able to recondition what you have and in my opinion this is the better choice as some aftermarket brake parts are poor quality and seep/leak after short periods.

Awesome thanks for the info. The older 1200s are just as rare over here. The Nissan 1400 is common and parts are super cheap but not the same unfortunately. I have an A15 motor already, i will be looking into a 5 speed and newer model diff replacement then parts will be a bit easier to source. Just the front brakes and suspension will be a mission.
 
I did try adjust brakes but i see the top adjuster on one side is buggered so i need to find time to strip and check whats going on. Il try sort that and bleed the brakes and go from there. Once stripped and if needed, il get the shoes relined and the drums skimmed.
I figured the early 1200 all drums would be hard to get but you might still get parts
as suggested by BeeTwenty.

The early datsun 1200 coupes had the hubs you need for a front disc brake conversion
and you can use the whole lot as long as you fab some brake caliper brackets and use
the dual master cylinder that belongs to it.

You would be better off with better brakes if you are going for an A15 but if you can just
go for an A13 or A12 as the gearing even with a 5 speed is better for highway speeds
or in general as the b20 is so light that it needs 3.1 diff ratio to reduce engine revs.

The A12/13 rev better as well, smoother and much lighter than A15 block unless you
have a tall A13 block which is rare but comes with smaller bores and 77mm crank.

The A12 bored to 76mm and lightened crank makes a super light bottom end.

I had a worked A12GX motor from an ex speedway racer that was easily 10kg lighter
than a stock A12, which could be lifted so easily vs the stock A12.

The secret is to keep the B20 as light as possible as they are the lightest proper car
with protection from the elements that challenges a Lotus 7 pound for pound.

Thanks d
 
It came with the a15 already fitted but yes id definately like to go with an a12 with 5 speed and lower ratio diff, we get 3.9 to 1 diffs over here out of the Nissan 1400 which was sold here until 2008 and are pretty easy to source. 
 
My main concern is the front suspension and braking which is going to be the challenge. But before i get ahead of myself, i need to find time to strip it and check what the issue is with the brakes, may be something small and easy to repair.
no problems, wow A15 fitted must take off easily from almost any gear! I had 3.9, A15 and 5speed overdrive but still rpm too high, specially at a 100. My stock A10 59mm 4 speed 4.11 was the only combo that sounded good on the freeway up to 120kmh.

Yea it pulls well through all gears but yes rpm is super high, 4000rpm is around 75km/h so highway is pretty much impossible. I am looking at a 3.9 to1 diff with a 5 speed box when i have the money available.
 
I need to sort out the brakes, handbrake, brake lights and heat gauge first, then new tyres and a few oil leaks and then we can move onto diff ratios and 5 speed box and maybe change to an a12.
