ahhhhhhhhh the joys of a 1K mine used to pull to the left real hard under brakes haha. and the indicators and windscreen wipers got faster as i drove faster.

The drums and brake setups in the 1k get problematic as they get older. (understandabily)

I would suspect that the slave cyclinder is not releasing completly, so when you hit the brakes it comes on before the other side.
You may need to remove it and get it resealed.

Dattoman_1000 would be the guru on this...

As for the indicators, get a multimeter out and find where the power stops. It could be a broken wire somewhere.

Once you locate where the power stops, it becomes much eaiser.

Gday all, seeing as you are the datsun 1000 experts i was hoping you could help me out,

Problem 1, The right hand rear brake locks under hard braking and i have no clue why its doing this and is becoming rather dangerous, note brake system is completely stock.

Problem 2, My right hand front and guard indicators are not working yet the rear right is? the bulbs have not blown soo i am unsure what this is all about, this too is also becoming dangerous

Cheers in advance, Jake
