: drum to disc swap, need info & parts
sdweller 02-02-2002, 02:00 PM I am looking fo rinfo reguarding swapping my '67 FJ40 from drum to disc all the way around. Can anyone tell me what I need to get and where I might find it? I have decided to swap the entire front and rear ends to make it easiest but need to know what else I should consider while doing it.
Thanks for your help folks...

Pin Head 02-02-2002, 07:18 PM You will need either a stripped housing for a 68 and up FJ to do the mini truck disc brakes or you can swap an entire 76 and up front axle. There was a free housing on the For Sale board. The mini truck has some advantages as it uses a little stronger Birfield joint. There isn't that much advantage in swapping the rear axle. You can find some details at:

RHINO 02-03-2002, 12:30 PM ya know, when doing a front disc swap it is fine to use the p-up or newer 40 parts, but when a 4 wheel swap is definitly planned, i dont understand the reason for p-up front swap. what i mean is, you will put a vented chevy type disc on the back if you use the standard "kits" out there, so why put a non vented up front?
i dont have much info on this but the FJ60 i believe has vented disc, and there may be some aftermarket out there too,, so i'm just thinkin if you are going from drum to 4 wheel disc, might as well get a vented front too.
sdweller 02-04-2002, 07:04 PM Thanks. I will take all this into consideration when making my decision. Keep anymore good stuff coming. I can use all the info I can get.
Thanks again!

When you do the mini knuckle/brake swap, you keep the FJ vented rotors...... :)
sdweller 02-05-2002, 10:26 AM I hear there was an issue with the mini-truck swao and the older '67 FJ40. Can't remember what it was but it caused major headaches and a lot of extra work.
Anyone know what this is about? :smokin:

It has to do with the fact that these older axles used the ball and claw type joint rather than birfields. The axle housing lacks the surface for the inner axle seal for the birfield type inner axle. '68 up housings are cheap with someone giving one away on the POR for sale board.

Also, dont the early-67 3rds use coarse spline side gears? I know 68-up use fine splines......

Yep.
I am planning a 4-wheel disc setup on my 65 wagon. No questions on the front, but on the rear is the 65 housing the same as the later models. I plan to swap in a later model, 1977, 3rd member and axles and then do the standard chevy rotors and calipers. Thanks.
Halyourpal 02-06-2002, 04:44 PM I just bougt a 74 whit disk brakes and when i took off the front wheel... the way this guy put disk on was he installed (vented) disk on the spindel, bolted a pice of angle iron on to the caliper then welded (shity weld) the angle iron onto the birf housing . has any one heard of this befoe look real simple if that is what infact what he did.:confused:
It sounds like he welded a caliper bracket (angle iron) to the drum knuckle. This will work, but is it safe? I don't know if the knuckles are cast or forged steel. If they are cast steel, I would not use that setup. It is too difficult to get a perfect weld with cast steel. I would swap out those knuckles for some mini truck knuckles or something that has built in caliper mounts.
Ozrunner 02-07-2002, 08:01 AM I sent this rear disc setup out of an OZ 75 series landcruiser to a guy in the US and I believe he may not be planning on using it in his current project, but I'm not sure.
If your interested let me know and I'll ask if he wishes to sell it and if so pass on your email etc.
