z32 rear swap question

[ThE_BoMB]

Well got my parts last week and ive been crapping my pants trying to get everything organized and get my old calipers off and the new ones on. I have the brakes off a 91 twin turbo z32 (i believe). Anyways Im stickin with four lugs (i like my oem wheels :P). I swear i must be one of the first guys even to consider this job. (just my luck haha). Anyways looking at the major differences one being the huge extension on the z32 5 lug hub for the large bolt (4 lugs dont have that). And a metal dowel (oh yes it gets better). I think it was projectsilvia that did the swap except there was a bolt on the back of the ebrake drum (in the exact same place where the dowel on the hub is. Which then goes up through the large bolt and into hole in the base of it. (this i would assume is to make sure it doesnt move and to reinforce the ebrake drum itself. So to keep my 4 lug i will have to fab up a adapter plate so that it will work properly. (although im not concerned about the ebrake too much it wont be parked on a steep hill anytime soon).

Anyways has anyone else done the swap and stayed 4 lug and what did you do to solve the problem?

its a straight bolt on

i did it with 5 lug, only difference is just not to dril the rotor

this is a bolt on job

did it on s14 upright
did it on s13 upright
easy job just takes some time.

no adapter plate is needed.

I thought that at first as well but theres a couple inconsistances with the "bolt on" majority of it has to do with the ebrake drum.

except for this:

http://www.northwestnissans.com/board/attachment.php?attachmentid=11151 I dont believe 4 lugs come with this extension which would fill the void underneath that bolt in the pic above ^^.

http://www.northwestnissans.com/board/attachment.php?attachmentid=11154 see i can move it....

http://www.northwestnissans.com/board/attachment.php?attachmentid=11153 the back of my ebrake drum.

http://www.northwestnissans.com/board/attachment.php?attachmentid=11155different ebrake drum either project silvia or 240sx.org one notice the smaller bolt 1-2 inches from the larger one.

The adpater would be to fill the void underneath the large bolt because I dont believe s13 4 lugs come with that extension. The plate would be similar to the large bolt extension coming off the 5 lug hub

huh? its not bolted down.

i dnot konw .compare them w /pics
dont assume.

duh
its not bolted in. what the fuck do you expect??


http://www.northwestnissans.com/board/attachment.php?attachmentid=11153 the back of my ebrake drum.


yep it is. that side sits against the upright, the upper bolt goes thru and the nut on othre side. holds down top of ebrake drum assembly.

i dont get this, that part goes thru spindle. thats the right side of car one.

are you talking that large bolt on the last pic? because iirc, that goes thru the spindle and you put the nut on the back of the spindle, opposite side of the hub

i did my z brakes 2 times. pretty sure
even though i admit im going off memory but i was looking at it two nights ago as i installed the r33 lines on my s14

[projectRDM]

Exactly. Someone's been eating retard sandwiches.

The large bolt goes all the way through the spindle as well, compressing everything tightly once installed.

[ThE_BoMB]

Ok i was tired when i wrote this question, can you spare me the retard sandwiches.

Anyways. I am staying with 4 lug. As i said. However unlike project silvias or 240sx.org one i dont have a alignment bolt at the back of the drum. So regardless of how tight that big bolt is it can still pivot. Hence why i said a adapter plate (which would be very similar to the extension with the dowel pin). should be made so that it cant pivot. And last time i checked the 4 lug hubs didnt come with the big bolt extension with a dowel pin in them.

[Dousan_PG]

4 lug s13/s14 spindle is nearly same
both ahve that large hole there
why dont you start the job pull yoru car rear brake hubs apart and all that take look rathern then posting.

[ThE_BoMB]

Well just finsihed the swap today and i was right. r240na your a idiot. You obviously havent done this swap. there is NO extension OFF the 4 lug hub so the large ebrake bolt sits flush with the rest of the drum. YOU HAVE TO FAB ONE. but oh wait im eating my retard sandwiches here and obviously dont know what im talking about. :mrmeph: . 4 lug hubs and 5 lug hubs ARE NOT THE SAME. that extension in the pic where the large bolt goes through DOES NOT EXIST ON A 4 LUG, HENCE you have to fab it. so that the ebrake drum sits flush with the hub and everything works well. so R240NA SUCK ON THAT. So for people who think this is just a bolt on job YOU ARE WRONG. to get it done right you need to fab a plate to support the ebrake drum. But then what do i know obviously im a noob, so to the people who thought that F*CK YOU.

[projectRDM]

The tab is NOT required. You may have felt it was and spent the time making one, that's your mistake.
None of the five Z32 rears I've done had any issues, and I don't know anyone else who's had problems.
Quit crying.

[ryan hagen]

only z32 have that on the hub, buy a fuckin washer from the hard ware store, i did i it with z32 hubs and i was fine but you knuckle will hold that tight, just use a washer not some kinda over thought up adapter.

whoopedy do...

you could use some washers isnt exactly that small of a bolt and would have to cut the side off one i would assume 3 or 4 would be enough. but obivously you guys are too smart for me, over thought? reinforcing the ebrake structure through the hub is over thought? Especially when you use a pivot point like that for a 2700 lb car, and you can over think about safety? wow you guys are way to smart for me have fun parking on hills. :mephfawk:

[ryan hagen]

lol the 3/4" of cast iron in the knuckle im sure will hold you ebrake just fine, the washers would only be to center the assembly and keep the nut tight. at no point does the bolt have 2700lbs of pressure on it, it holds a leverage point. the leverage point pushes out the shoes on the drum and they hold it. bet the pressure to be no more than 30-40 ftlbs tops on the bolt. its isnt that big of a deal. look at the cheesey backing plate bet that would give out before the washers. :hsdance:

I dont quite think you know what im talking about. Im talking about the big bolt that goes through the spindle. The backing plate does not have anything to do with the ebrake. The only parts that connect to it are the anti rattle springs and arrow bolts that apply pressure to the pads so that they sit in the correct position and dont rattle. All of the ebrake is centred on the pivot point being the large bolt. the leverage point is on the other side with the adjustment bolt that pushes the other side of the ebrake pads outward towards the drum. all of the weight used in the ebrake is solely on those bolts. And i highly doubt that nissan made that extension on 5 lug hubs for no reason.

[RichthePoser]

Cant you just use the z32 backing plate?

I will be doin this week in 4 lug.. dam rotor drillling is a bitch.. hope you got the master cylinder as well..

[ryan hagen]

regaurdless you only need washers or something to space out the ebrake assembly so it matches up witht he drum, the extra 3/16ths or maybe 1/4" of a inch that is the thickness of that tab wont make a difference in weather or not you ebrake bolt tears through you 3/4" of a inch of knuckle, i d bet if anything that tab is for the z32, which is what they come with that uses a aluminum knuckle. i just did it right and got z32 hubs to use with my z32 e-brake set up. teh s14 hubs that are 5 lug dont come with that tab so it has nothing to do with 5lug, only the drum ebrake which is on the z32 with a aluminum knuckle. so i still say its is nothing to worrie about.
