hiya..

am needing some help from anyone that may have done,read or seen somewhere in their personal experience or online adventures,a bolt on rear disc brake upgrade for a landcruiser 60 series diff.. am putting these under my 40 and since i have the things pulled apart for refurbishing and perch adjustment, may aswell upgrade em

have stripped rear diffs (and front) back to nothing so have of course removed the rear brake housings etc.. was sort of hoping there would be something that would bolt on... doin it right is the goal...

must be noted that i want to keep the standard housing and dont really want to get a different complete diff, off a prado for instance.. want to upgrade what i have, not buy something like that... $$$$$$

any insight and help would be greatly appreciated and received...

thanks..

anybody?................

Sorry dude, unless you want to import from the states, You just gotta get your thinking cap on and design/build your own.

Iv'e just done mine with soild hilux rotors and front subaru calipers, Made a template out of 3mm slimline for the bracket and the rest bolts on.

ill be doing my rear disc conversion in a couple of weeks. My old hilux solid rotors and some kind of caliper. Ill keep you updated

ah yes rokhound.. thinking cap.. worn mine out.. too much thinking about the build already. would the solid lux rear bolt onto the rear housing of a cruiser 60? need a shim/spacer? i was reading on ih8mud a chap used a gq patrol rear disc and subaru something caliper i think... whats the difference between the cruiser and subaru calipers? size? grunt?

would like to have a closer look at your setup sometime if ya didnt mind rok.. keen to try and do that, if not something similar on the 40...

any replies are welcome..

The hilux soilds centre is 6mm too small. Im having the rotors milled out rather than the hubs with the caliper on the front of the hub rather than from the back.

Is the 60 series any different from the 40 series in the hub cause my landi has 40 series diffs with disks on the rear i was told the are holden calipers and they are big disks! and grubty lookin calipers i can take a closer look if it might help you out

yes please a couple of pics and a bit more info on them would be awesome... thanks...

Will do after work 2morro for ya im not sure of what model holden they are off but i can get pad numbers from their you should be able to find what caliper it is but i will rip a wheel off and take some pics i havent figured out how to post pics up yet but if all else fails i can put them in my gallery

Hey Nib if your willing to wait I'm gona have a fj45 in the shed in a couple of weeks.... if you want I'll see what I can sort for ya
The holden ones that RR is talking about is possibly a 2 pot off an XA or XE(can't remember which ) coon one of the few twin pot rears with a cable brake as well
Another option to look at is what I'm doing I've used a set of hilux 4pot solid rotor calipers on the axles and I'm going to use a trojan cable disk brake on the rear of transfer case for my handbrake

It seems like a lot of work for the rear brakes considering they only do about 30% of the braking, Is there a reason why you all are going for discs on the rear?

How often do you have to change your rear barke shoes because of the shit that wears them out.
When rock crawling, if you have just come out of the water and REALLY need the brakes to hold while the spotters sort your next move, drums just aren't up to it.
That's my reason any way.

(PS Was that your truck I saw yesterday in Estuary road with a modified front gaurd Aaron?

Sounds fair enough,

No not me my truck is at home with an alternator full of mud!

2nd time its happened in 3 months its starting to piss me off.

Yep mine was exactly the same.
Have now ripped off the power steer pump and resevoir and will relocate the pump to bottom of the engine, and put the alternator up the top. (should have done it during the build , but was too lazy ahhh hind sight eh?)

In my case I get a real kick outa building and modifing.... you just have to look at the money I've spent in my shed
Modern cars especially 4WD's are a comprimise ability vs cost with cost winning
This gives me plenty of room to play if I can get an improvement over standard I'll do it .... why do you think I haven't finished the lemon (my currant project) I keep changing my mind and modifing what I've already modified ...

Rear drum brakes are crap - especially on a Hilux , it can one be muddy trip and your brake pedal is going off and there is no handbrake left.

I've now done two of De-Ranged Maxima caliper conversion (both on lux axles) and they real easy and seem to be working out quite good without having to change the master cyl so far. My album has some pics.

Here Here Deranged. Well said. (but if you just change that bit over there..... and move this in here..... )

i'll check your pics rangie-lux.

rok: did ya get that pm i sent?

aaron: reason for 4 wheel discs? mate, if ya askin that, ya dont know the benefits .. stopping prowess, maintenance, the ability to work well when been submerged in mud, silt, water and like crappyness (as rokhound stated).. plus the fact its another modification for the truck to help stop when i get my 38's

also rok: thanks for bringing up the alternator vs water scenario... must remember during the build to relocate/swap my alt and pump around..

Already high on a 3B Nibby!

ah..

oops...

wont do any good if i drive like you though h2o... (read: refer avatar)

You'll notice in my avatar that the truck is pointing down into the water. So if i'd mounted my alternator at the bottom maybe...............
Anyway it was the easiest way of clearing all the mud out of my electrics. Maybe if i'd had the winch on then it wouldn't have crapped out in the weekend

Cleaned the mud out of your electrics??!!

you cleaned out the whole truck that day!!

It was the easiest way............. Maybe, with all the bad press us 4wders are getting , i should change it to something a bit more PC

Um these are a really big single with no cable allowance the look suspiciously like a front caliper and running 14inch solid disks sorry no pics im scared of the rain i would get wet workin on the landi(no shed) but i will get them very soon for ya sorry.

forgot you wouldn't need cable brakes on rear axle .... having a tran's brake and its not like I havn't had any Landy's |-)

Anyway thats another option for ya Nib, I'm pretty certain it was the XE coon that came out with rear disks.... they're hard to get but mean! and they have cables for handbrake

Hey Rok the most destructive thing that you can do to a project is to start asking ....."But what if....." When I first started the Lemon I talked to suprasurf and he sugested a few extreme ideas, that I flaged as to extreme.... I was thinking the other day I've done or exceded each of them now

Cheers Reece

i dont have the handbrake on the rearward driveshaft, so a rear disc option with cable to back axle is the way to go for me..

de-ranged: no such thing as TOO EXTREME..

just more time for mods needed.. thats all.. ]:-) do the xe coons bolt on or more modifications required?

keen to learn more...

RoloverRover wrote: Um these are a really big single with no cable allowance

you mean no handbrake to the rear axle? if so, this may not be the conversion for me.. i really want a conversion where the rear axle has the handbrake and the discs too...

which are better discs to use, solid or vented? thought vented would be, yes?

Yep sorry i meant no hand brake on the disks. If it was me settin it up i would definitley set it up with hand brake on the disks and vented disks may not be the only way to go how about slotted or cross drilled they would prob clear water/mud even better than just vented disks wouldnt they? I guess it also depends on your front brakes as to how good you want the back brakes to really be the last thing you want is the back to grab to early and the front still be rollin free unless you use a brake splitter

You have a few options as I see it... is your rear axle full or semi floating? With the full floaters I've seen modified swivel housings from Hiluxes cut down to mount the caliper... if its semi then use the same setup as Hiluxes - just mount a caliper (E33 Galant, Maxima, Subaru, etc) and slip the rotor over the hub after removing the drum bits (machining required as discussed above).

The MU also has the disc conversion (its a surf axle in the rear), so you can shoot around and have a look at that if you want.

If you don't want a handbrake setup on the calipers you can easily set up a cable-operated caliper (trailer or gokart) on a custom disc mounted on the output of the t/c

Don't worry about vented rotors in the rear - its unneccessary overkill... and you'll have fun finding a caliper big enough to work on it that has a handbrake option.

as ive found out, the 60 series would have a different bolt pattern to a 40 series one. And I'm pretty sure we're talking about 60 series axles. They have 4 bolts as apposed to 8 with a 40 series. Besides, cutting down a hilux swivel housing is a waste of someone elses disc conversion
