Diskbrakes on FF

[solli]

Diskbrakes on FF-more questions....

I have read this how to, Rear Full Floater Disk Brake Conversion , but 1 question;
Did he weld on the bracket?

 

[S4Cruiser]

Looks like he just used bolts

 

[CruisinFJ60]

x2, looks like a front knuckle attached to the rear somehow and a stock front caliper would bolt right in place.

FYI Toyota did make factory disk brake full floating axles in the 9.5" diff housing. I am running one now and have a spare in my car port.

He cut the piece of the front knuckle that have the tabs for calipers .. IMOP to much work for rear disc brakes ... can be way more easy than that ..

Is that parts from a 80?

I would be glad for some tips how to do it simply, or if someone could tips me about a company that makes a bolt on kit. I can find kits for the semi float axle but I now have a FF.
My axles, front & rear, on my HJ 45 is from a BJ 75 and then I have the same brakes as an 60. For normaly driving it's OK, but on our club's offroad area there are som muddy parts and after I have drive in the mud the drum brakes are useless

I've done that conversion a couple times now, all parts are from a 60 or disk brake 40. Or even mini truck for that matter.

Pretty easy conversion, certainly stops well afterwards. Nice having all the same brakes and bearings front and rear.

Brackets bolt on with the same bolts that attach the spindle on the front end, can't find the pic I had of the brackets, but yeah, you basically carve up a set of disk brake knuckles to leave the caliper tabs and about half the spindle mounting bolts.


Only real pain in the process is having to turn a bit off the hub so the rotor fits on the back the way it does on a front hub.

Cutting up the knuckle for brackets doesn't take all that long..

Sometimes need a 1/4" wheel spacer to clear the calipers, I used the centre from a couple old disc rotors.

cheers,

Thank you for links and answers.

on a different tangent...is there a proven solution for disk brakes on the rear FJ60 axle, 1986 vintage, semi-float US truck?

 

[77cruiser77]

No, from my understanding the 80 series runs 8" diffs. Mine are from a Post 1990 HD 70 series as they had the same diff size as the 60 series in the rear only FF and factory fitted with disk brakes

 

[Fast Eddy]

No, from my understanding the 80 series runs 8" diffs.

A rear, fzj80 full floater uses a 9.5" ring gear. The front is 8".

 

[CruisinFJ60]

A rear, fzj80 full floater uses a 9.5" ring gear. The front is 8".

All 80 rears use a 9.5" third, all fronts are the 8"

Ive had good luck with the 4runner v6 calipers in the front and the chevy disc/monte carlo calipers in the rear. I did NOT swap out the brake master for the T100 stuff, and the brakes work well for me.

I do not have an E-brake with this setup.

You may want to look at getting an 80 series full floater axle, in the long run it would be easier to grind the perches off and have new ones welded on then to fiddle with custom brackets and such. Though you may need to swap your old third if your front isnt 4.11 ratio. Or better, upgrade your front diff to 4.11 if it is 3.73.

To convert to full float with discs, your gonna need,hub, spindles, bearings, axle shafts (maybe custom lengths) calipers with e-brakes, discs, e-brake cable connections, adapter plate for caliper welded on, hub flange (from axle shaft to hub), brake lines, etc. It adds up quick.

The other easy option would be the outers off of a full float 80 series with the axle shafts included, then cut off your outers and burn on the 80 series outers.

sorry for the sidebar discussion....


I have 4.88 gears in the front and back plus lockers, so it would cost me some additional $$ to change axle assemblies. What brackets are you using and what other modifications have you made for disk brakes on the rear of a FJ60 semifloat axle (OEM Drum setup). Would be nice if there was a good emergencey brake solution too. I've seen where some guy had a emergencey brake setup on the rear of his tC... rotor is mated to drveshaft flange and braket for caliper mates to rear of transfercase, never was sure that this was someone's custom setup or avalaibel for sale?

Elbert .. I post the link few post above ..

FJ-40+ Land Cruiser

Bolt on . I have TSM e-brake calipers and are useless with my 40" ( even with my old 37" too ) but if you try the t-case TSM solution and that works for ya let us know ..

FJ 60 Land Cruiser

End note: your rear 3rd will bolt on any FF 80 series rear so you con keep your gears and locker.

 

[cody c]

About 4 or 5 parts needed:

Ive got the ruff stuff caliper brackets, I would probably try the TSM's if I did it again as the rS stuff didnt line up very well. Or make my own, sounds more intimidating than what it is.

Monte carlo calipers with new pads(pretty cheap for new ones), soft lines to connect from the hard lines, I think from the front end? cant remember. Maybe they were off an 80 as I think they had banjo bolts to the monte carlo lines. I'd have to take a look.

Chevy truck front rotors (like $45 a piece) and had to have the centers lathed out to match the semi-float centering ring (real easy, took em to a machine shop gave them a I.D. cost about $50)

Bled the lines, and it stops great.

I think TSM and maybe tom woods sell t-case caliper e-brake kits. Apparently they work well but you should have a locker in the rear.

I wanna see one that works .. coz I have my doubts ..

I used a HZJ73 rear axle with OE disc brakes. I don't know where you're from, but in my case it was the quickest, cheapest and easiest solution. I traded in my drumbrake rear axle (in need of a brakejob), paid 100 euros and took the HZJ axle with me. All i needed to do was to reweld the spring perches and put an adjustable proportioning valve in the brakeline.

If you're in Europe, this might be a good solution.
Works like a charm too!

I think this is the easiest way. I hope I can find one this winter.
