I think if you used a flat plate for your caliper bracket, somewhere between 10-12mm thick, your life would be a lot easier. The cantilever and those spacers make me nervous.

 

No doubt it could have been done a different way. However the setup is rigid, the caliper brackets I used incorporate curved sections which give it strength even with the sections I have removed.

 

Either way I'll report back when it (if) the car runs and I have tested them.

Well, I'm glad I stumbled upon this thread!

I've recently acquired a WP411 project car and one of the first things I wanted to address is the brakes as I've got to put the system back together anyway. Have just started digging around the internet for information before I measure everything up and start sussing out what other OEM parts I might be able to harvest for it.

 

Do you know if there's any truth to 240Z stock front brakes fitting these?

Cannot confirm the 240z thing, but unless they come with a separate caliper bracket to mount the caliper I can't seem them working on NON SSS 410/411 hub & spindle. A SSS one maybe if they come with a caliper ear, but I haven't seen a SSS 411 spindle yet to compare.

Making progress on this conversion & car as a whole, thought I'd chuck an update for completeness.

 

Tack welded the spacers on the brackets using a clamp, then painted

Got hubs machined to suit the rotors

Rotors fit perfect now

Will be repacking the bearings then installing everything on the car.

 

The 410 bearings that are installed in the hubs for reference

 

Front of stub - Bearing 30304A (NSK Brand)

Rear of stub axle - Bearing 30206 (NSK Brand).

Hub seal - 40227 08000

 

Does anyone know of a longer wheel stud that can be used on the 410/411? Now that I'm using a slip on rotor, it's slightly thicker than the drum face, so want to make sure I have enough thread on the nuts.

 

Thanks

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

Wow thanks man! So you fitted yours and all good?

Are they stock length or longer? I'm googling to see if I can find an equivalent in Australia, otherwise I'll see if Amazon ships to AU (without wanting my first born child).

No problem, fit exactly as stock. They are longer than stock though to make up for the rotor thickness, as well as a bit more thread engagement for the wheels I am running. 

 

Edit to add a pic of them installed.

Dug out all the old grease from the hubs on the weekend and cleaned all the bearings.

 

Did a rush job of painting the hubs

Banged a stud back in and test fitted a rim with the disc on, gets full thread on the nut so all good for studs if the calipers fit (which they probably won't)

Next stop is repacking bearings, getting some proper caliper bolts that are the right length, then trial fit it all on the car.
