first and foremost thank you for welcoming me to the forum I seek some advice and knowledge I apologize if my format is incorrect

I have a 89 Toyota pickup it is 4 wheel drive the VIN indicates a 8 inch rear end "g292" but I dono



My dif

because I have 2wd brakes.... yep duo servo brakes


therein lies my problem apparently the duo servo rear drum brakes are extremely rare autozone O'reillys advanced and the dealer believe it or not cannot get me a part or even a part number for adjusting lever, spring and the adjuster itself I have looked on forums and have found little to nothing on dueo servo brakes





My adjuster driver side i beleve

With that being said can any of you help me with a part number or a resolution aside form $500+ disc conversion

Switch axles like with hub from say


To

But will my e-brake convert?

or whole diff ?
Do I have a 2wd 7.5 rear diff on a 4x4 truck ?
any help would be very much appreciated thank you

 

Who can say just what ends up on these trucks.

I have never seen those brakes in person.

What kind of Ebrake set up do you have with these brakes. What does the intermediate lever look like might be easy to then swap to the bell crank style ebrake system.

I wonder if the axles are the same then a simple switch of axles with backing plates to the more easily had brakes.

Otherwise it might be easier to swap the complete rear housing.

 

don't get hung up on the nomenclature that you are seeing in the manual.
Notice too that you are looking at a 2WD brake in the manual.. not that the 2WD and 4WD have any big differences.

Your rear axle has 6 lugs...unless someone stuck a rear axle from a 2WD Taco Prerunner(had 6 lugs) any other 2WD axle is gonna have 5 lugs.

Just ask for a rear brake service kit for your 89 4WD. It should have all the springs and misc parts that you need. I can still get them for my 81's rear brakes from AutoZone or any place like that

 

Why do you have a spring over the axle? Zuk mod? Is your suspension stock?

 

I wonder was that truck brought home by someone on Uncle Sams Nickle ?? Built for a non domestic market.

While it does have a 6 lug axle I have never seen any springs like that on any adjusters on All the new spring kits I have here .

From The Solid axle 83 I had up to the 2000 Tacoma

They sure don`t come stock with any kit I can get

As the lower brake picture is the type that seems to be the normal so to speak

 

I wish it were that ez explain to me if I'm wrong

let me clarify my self drop zone the last 2 photos represent a contrast from what I have to what is common first my truck second a 95 4runner with the standerd brakes notice the placement of the wheel cylinder I couldn't put any other shoe on the hard ware and cylinder would have no ware to go as well :-(
But man o man do I wish that would work

 

[QUOTE=JKelly0117;52272524]Why do you have a spring over the axle? Zuk mod? Is your suspension stock?[/ing the sorry for not properly describing the photos of the last two the very last one is a 95 4 runner not my vehicle just put on there to show contrast

 

what is super weird is I went to O'reillys and they had the shoes and hardware kit for my brake system but not the adjuster and of course I'm missing one of the springs and the adjusting lovers are pretty warn the guys who have the truck before me use zip ties to space out the adjusted how redneck is thatI will post more photos but if anyone knows anyone who might know something about my brakes that would be awesome

 

that third looks like the standard 4cyl diff that came on all of the pre-'95 4wd 4runner/trucks.
