What rear axle are you planning on that has a parking brake?
80-83 FJ40 or FJ60?

Love the bin organization. That must have been Kavi’s idea! Haha

70 series

70 series in the back 40 disc brake axle in the front.

Another lesson on what we plan to do on the engine and more...

The venerable 8274, the Land Cruiser of winches. Another great find on this truck.

Here are some more ideas for Old Landy...

If you're going to put late disc brakes on the front anyway, go ahead and upgrade to '95 4Runner calipers. Much more stopping power; Old Landy must be pretty heavy.

Looks like we will be eating Ramen for a while . Warn 8274 is a gem indeed.

What is planned tire size? 33"? 4.11 might be a bit deep on the street with the diesel. I'd drive it with the 3.70's first.
Also, bigger calipers on 40/60 discs don't really help, it's more of a placebo then most realize. Rotor diameter is what really makes the difference, then use bigger calipers to compliment that.

Great project. The 8274 and all the extra parts are awesome.

All that colorful lead paint preserved Old Landy quite well. Just don't eat the paint chips...

Looks like I may have that same vintage ARB compressor.

Caliper piston size, as well as pad surface area, are indeed variables in braking force since they are both means by which the hydraulic pressure in your brake line is transmitted to force and friction at the disc.

Read what I posted again. Maybe slower.
Of course they are, I didn’t say they don’t matter.

The 60/40 brakes can already lock up the front rotors if paired with the right master cylinder and everything is in proper operating condition. Upgrading calipers that can already lock up brakes doesn’t make sense.

Big calipers on stock discs don’t help, but rotor size makes the difference. How’s that?

OK sure, stock calipers can lock up, but calipers with larger pistons require less pedal force to create the same braking force. Are you saying that’s not an upgrade? What am I missing here?

Still not sure how rotor diameter plays into this.

Because that will just result in warped rotors.

Bigger rotor = more surface area for pad grip and heat dissipation.

Great discussion. @Cowboy45 who is 13 is getting diverse thoughts here which is something I advocate to him. I have asked @Cowboy45 to do some homework on this. First:

1) determine rotor size, caliper size, and brake pad size for fj40 disc, Stock OEM.

2) determine same attributes as 1) above but for a ‘95 4runner disc brake system

Then compare to see impact of 4runner caliper only on stock 40 disc vs 4runner caliper and rotor change together.

I’m on it!!!

Love this thread. Not much rust in my view btw (and CA and AZ guys normally freak out at any indication of rust). I would shoot a rust converter on it for the time being. Nice platform for your project!!

I don’t think you’ll find anyone whose put the 4Runner/IFS rotors on a 40/60 spindle. I don’t think that’s been done. However you can look into the FROR Tacoma brake upgrade. Lots of parts to change though with that.

I think 40/60 front brakes, with everything fresh, will be great.
Assuming planned tire size is 31”-33” right?

I remember being 14 and starting to mess with my FJ62 with my dad’s help. What great times. Before you know it he will be teaching you all kinds of new stuff.
I just wish my dad was more into these old Land Cruisers then racing sports cars
