Solid axle rotor?

[86yota]

I am working on building my $50 front axle now.  I need rotors for it.  I dont know exactly what year it is, it's got to be an 80-83.  When I went to look up the rotors for it I noticed a different part number for 79-80 and for 81-85.  There both a solid rotor and the same diameter.  I assume they are the same thickness as there is just one caliper number for 79-85.  What is the difference?  And if it is an 80 can I just put the more common 81-85 rotors on it?

Early rotors have 2 bolts holding the rotor to the hub, later ones have 6 bolts.

I guess that's why for the differant part numbers. wasn't sure my self.

[86yota]

Just went and looked, Yippi!!! I got the two bolt 1980 version.  So is this design pretty weak or what?  Should I scrap these in favor of later ones?

[86yota]

Oh yea.  Is there anything else different about this 80 version that I should know about, spindles, knuckles, third, shafts, etc. before investing money in it?

[WHITE_TRASH]

Nope, basically all the rest is the same stuff.  I wouldnt worry about the 2 bolt vs. 4 bolt, both are plenty strong.

[86yota]

WT,  you are a wealth of information.

Glad to be of service, I figure Ive screwed up enough yota stuff to at least pass on the what not to do's to everyone else.

[86yota]

Hey on the plus side those early rotors are cheap.  I was going to just do the ifs hub thing, maybe later, I want gears, a locker, and new trunion bearings right now.

[WHITE_TRASH]

I havent used solid rotors in a long time, I still have all hte old ones lying around though.  When I forst started messing with my 81 last summer I niticed that one rotor was about 1/4" thick!  Glad a I kept all the old parts hanging around then.

[86yota]

At least you were smart enough to keep all your old crap, my dumb ass sold EVERYTHING when I moved.  I should have just made a dozen more trips back and forth and kept it all.

Having a stockpile of parts goes hand in hand with being a cheap bastid that I am.

Yea, and that's why the 10x20 storage unit I just got isn't gonna be big enough ...but when I need it stuff is there,    Nate

on on a slightly different subject...what kind of upgrade rotors can i get for my '79?  aren't there a certain year land cruiser rotors that'll work?

i know that also brembo makes aftermarket rotors for 70s-80s cruisers with slots or holes...

[WHITE_TRASH]

All cruiser rotors are 6 bolt as far as I know.  I had to drill the smaller 6 bolt pattern into my fj rotors when I put them on the 94 hubs.  It would be very simple for you to do the same type of thing.

I swapped 1983 FJ-60 vented rotors, hubs, and calipers right onto my 85 with no trouble.

Hope this info helps.

[kyle_22r]

if i remember right i think cruisers had the same break(pre-81, 81-up) as pickups.  not completely sure though

[kneedownnate]

If you wanna go with the wider vented rotors, I think 81 was the first year cruisers got them.  I researched it and all the bearings and seals are the same, so it's a straight swap,    Nate

[WHITE_TRASH]

76 and up have vented rotors.  Most people believe its 78+ that got the fine spline pinions and disc brakes but every 76+ Ive ever seen has been so equipped.

That's not being cheap that's thinking ahead.
