Hey guys,
 
I've got a 411 wagon that has 4 wheel drum brakes all round. Considering a front disc upgrade to something to something like a solid disc and single piston caliper purely because you just can't buy the drum gear for 411's anymore.
 
I see maddat does a 1k disc upgrade so I'm interested to see whether the 1k front suspension arms and spindles are similar if not identical to the 411 gear.
 
Any help appreciated. Also if anyone has some suggestions on calipers and rotors that may suit that are off current models and easy to come by I'd love to here your input.

I'm aware of the sigma upgrade, but would prefer something more current & mainstream.

Cheers

Tell me more about Neils lazer setup, or a link if possible. Any idea what rim they fit under?
 
At a guess I reckon a solid rotor would be an easier fit, but open to a vented rotor if fitment around steering items isn't a big issue.
 
I might try and bleed the drums and see what love I get from the cylinders as an interim as it will only be powered by a J15, but longer term I'll need to replace all that stuff.

I don't think these brakes have been used for at least 10 years so it's not promising.

Also have a look through this for pics of a standard 1000 setup.

Just look through the topics within the service section on the links in the left.

I use KC Laser calipers and discs on a fabricated hub

I took a couple of pics of a 320 ute today that had disc brakes
Not sure if they are similar... will upload once I dump them off the camera

They look like a15 vanette ones judging by position and caliper if not mistaken

You don't need to weld anything if you have a nice flat spot to bolt a bracket too
 
Then you just need to adapt the disc to fit
My original car had fatcory hubs I drilled and tapped to accept the disc
Later I decided to make a hub to do the job
 
If you can find a disc to slide over the hub with the right offset it makes life easier and no need to make a hub
 
Take a look at some of the 1000 conversions for ideas

Welding up holes in a bracket to redrill new ones isn't an issue for the R31 rear conversions, I've done it myself on my 180b. I was referring to welding 2 pieces of metal together to form a caliper bracket to do a front caliper conversion.
 
I'm working on the motor for this thing at the moment, hopefully can get it assembled and installed then I'll move onto the brakes.
 
Apart from replacing the master cylinder I'm hoping the drum brake gear isn't seized, time will tell.

I'ved used pulsar discs and VL calipers, with a proportional valve for the back brakes.  At a later date I think I will look for an upgrade to the rear.

Just coming back to this. I have been doing some thinking over this and thought it may be easier to find a replacement spindle to knock over a bunch of limitations for brake upgrades, wheel fitment etc.
 
I came across an article from the USA talking about 1991 nissan hardbody drop spindles (which are pathfinders I believe). Which led me to find a ratsun thread where someone said (and put up a pic) they bolt onto a datsun 620.
 
Looking at them in the photo they actually look like they may work on a 411 to.
 


 
 
A stock hardbody spindle fitted to a late model 620 setup.

 
I'm still a way off getting to that stage, but those drop spindles would work a treat especially if I bag my wagon, just need to find a suitable hub or fab one. Knowing nissan plenty of hubs probably fit with a 4x114.3 stud pattern.
