Outer Limits 4x4 Board

Chris

As you know its now past 12pm zzzzzzzzzzzzzzz so just a short note.

I will remove my wheel tomorrow night and take some pics of my setup. My bracket is also 10mm (3/8") and it is straight except for about 3mm added so the caliper can float etc.

Joels is mounted inside mine is outside.

I think I may have an old 75 disc in the shed but I have looked at all this previously and it didn't suit the clearances required for the 4Runner. But it maybe OK on leaf truck.

JD

Thanks JD

JD... you are the back yard engineer, booty fab God

There are 2 differant sizes in the calipers in subaru not sure if its pre 85 or after

Chris

After removing the wheel there was not really much to show and I must have thrown the old 75 disc out as I couldn't find it. It was a rusted one a wrecker let me have to check distances with.

So here's some old pics when I was fabbing it that show my bracket.











I made my bracket so it is a snug fit around the bearing housing so it also acts as additional support and its positioing is then governed by this centralising rather than lined up using the bolt holes, ie it can only be bolted up central etc.

As previously mentioned this involves having the front disc centre hole machined to 106mm and I also forgot to mention that the outside axle edge has to also be machined down a few mill so it will actually go inside the disc. With all my projects I have a tendency to not only consider what will work but it has to also look like it was meant to be, so having the disc machined was not a concern to me nor the axles as they are already hybrid, being Toy axles recut to a Dana44 spline, .

Joels bracket could be used in the same fashion, ie bolted on the outside, if guys went for the 151 disc and had it machined. I now recall why the 75 was not a good option for mine as the shocks were in the way so I had to come up with an alternative. The 75 disc is 12mm shorter than the Nissan and cannot have a straight bracket as the bracket needs to basically line up where the axle tube flange is so it will need to be stepped. It could easily be machined out of a thicker piece of steel to suit or if ok with an engineer another piece then welded to the main bracket to form the step.

Using the 75 disc would be a lot easier in the long term as its a straight bolt up and replacement etc so having some dedicated mounts machined up still makes better sense as once they are done and bolted on they are on for keeps.

If an engineer will pass a slightly larger centre hole then the Mitsi 233 would be worth considering as its 108mm meaning the centre hole is only 1mm larger than the Toy radius,ie 1mm each side = 2mm which is a lot closerand really bugger all as rust would take that up . Its 84mm wide meaning if 4 additional 4mm spacers were welded to Joel's bracket at the flange mounting point to space it out a further 4mm its done.

But this is Joel's post and baby so its his call,

All I was trying to do was point out the caliper that was proposed to be used would not work and you would all be wasting time and money.

JD

Thanks JD. This is the best tech I have seen on toyota rear discs

FRONTERA 4 X 4 Rear
2.0i with & without ABS 3/95 - on
Sport 4 X 4 UT 10/95 - 6/99
S & SE - V6 & 4Cyl 2/99 - on

diameter - 313
height - 81
thichness - 18
centre hole - 101

would the 1mm difference in the height be a big problem? These would need to be machined to open up the center hole.

Note the PCD for the frontera is the same as a hilux 6 x 139.7

Chris.

I am using frontera rotors on my current disc brake setup and they work well, Rotors are actually located by the centre hole and the brake drum surface around the axle flange if you do it right, I also locate mine with 3 8mm c/s setscrews

What callipers are you using? is your bracket flat like the one Joel is making?

Chris.

sorry for the late reply, been away, my calipers are ea falcon rears, and required figuring out a custom handbrake cable setup. the handbrake on these is only a secondary one as i have a tx case mounted one.
My brakets re modified ea falcon ones mated to a stengthening bracket.

just a question, when using 75 series discs, can the 75 series callipers be used as well to save modifying the subaru ones??

JD, are you able to tell me if the calipers with 122mm bolt spacing and a 22mm width in mounting bracket (for disc width) is the one that suits an 18mm vented rotor, Have 4 of these calipers floating round (none have pads) and I am wondering if they could be used with frontera rotors (have spare) and joels brackets.

Joel !!!!

Thats the ideal matched setup but the problem is you will have no handbrake . The 75 uses small internal shoes inside the disc.

No point as the 122mm bolt spacing calipers are the large volume ones and won't work. You need the earlier 18mm disc model with 102mm bolt holes. I would keep the EA's.

JD

I chose the EA as they were already a rear caliper. I have no reason to swap them out as they are engineered and work well. Was going to take up joels offer as i have a couple of spare rear housings/assemblys in the shed and may have use for another disc setup. do you know the bore size for the early suby calipers, i think the EA's are around 42mm by memory

Is the 75 series a floating calliper?
If not I don't think they would work very well on a semi floating axle.

good tech guys but bickering over what works and what doesn't when you've all done things differently, some harder than others, won't get this idea off the ground.

I read all the posts and still have no idea what works and what doesn't.

can those who are driving daily on an engineer approved setup just post the specs of it and be done with it.

That way everyone else can do the same and the brackets can be made!

Chris

what happened to everyone?

dunno, still waiting for a package in the mail...

Im waiting on 2 also. They will be going into zuks running hilux diffs and GQ master cylinders, so caliper piston size dont worrie me

Got mine today, thanks stumpy, they look good

Got mine a week ago. Look Good. Wont be in for a while though.

just read thread, does anyone know if the housing bolt pattern out of a hilux is the same as a bundy? I have a bundy rear, & am looking at rear discs soon. I remeber when i swapped the hilux diff out that the drum brake setups were different, but do not recall if the bolt pattern was.

I was planning on using early suby front calipers (18mm) with GQ rotors, also (18mm). the lad i was speaking to who already used this combination said the rears always locked up before the fronts, as the suby front calipers are 50% larger than an 80series rear caliper. So if i adjust this to use 75s rear rotors, machine the ID to suit the bundy, i should still be able to do this?

if the bolt patterns are the same, & you are keen on making another run of these, i would be interested.

Peter.

wish i saw this thread earlyer.. i woudl have bought some :(

bring some complete bolt on set ups in that use the standard slave cylinder and handbrake cable with internal drub for the handbrake

was that directed at me?

------------------

anyone looked at using the hopper stopper universal rear kit??

looks the goods,.alot of cash tho

any one got theres fitted yet

any more still out there to buy?

Yeah, what he said... can some people just post some combo's that have worked... with or without joel's brackets... my head's hurting trying to make sence of all this. Thanks

Hey guys, With all these conversion taking place im guessing there's a few old COMPLETE drum brake setups lying round.
Im looking for a complete set preferably including handbrake cables for a little project on my patrol. i still wanna use drums so it looks factory, but want the handbrake setup in particular on the rear brakes. I figured the easiest way is to fit a whole hilux assembly on as that way ill still get the right stud pattern and it will be cheap.

Im guessing a carton will get me a set ?

Thanks Guys

PM me

I'm cheap and easy. A six will do and i'm Carlingford (Epping)

Cheers Joel

btt

i can supply these brackets that Joel did, they will be out of 8mm mild steel, prices have gone up since early 2006 though since it's almost 2008 so $48 a pair incl postage Australia wide.
pm me if interested.

Cheers Chris
