2005 Bulletproof Taco: 1 Ton SAC

More info?

 

Solution to all relationship issues "sell everything you own and it'll magically make things better" Don't feed into the bull shit Monica.

 

I need bump stops, I'll give you $200 for yours, kthx

 

Post-SAS needs a bigger master cylinder, 1Ton T100 master is 1-1/16" bore and works perfectly with 4-wheel disc brakes on tons. I kept my pattern and there's a few that have asked me to make them one.

For me this master put the hydraulic ratio exactly back to stock in my application, giving a stock feel to the brake pedal. No mushy pedal or long pedal travel.

 

Good info. Might be needing one of these adapters.

 

^FIFY, but yes...
ask me how I know.

 

Life definitely wins over truck shit! But dont get rid of it geeeez.

 

Wondering if it would work for those going to rear disk brakes like myself for long travel applications.

 

I'm running rear disks with stock front calipers and the t100 master is to big. I had to switch back to the stock master.

 

THIS ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 

Agreed! I sold BR only to regret it and bought an 85 4Runner.... I feel stupid starting all over again. Hang on to Yur rig man...its just a cycle...unless of course someone offers a ridiculous amount of money for it lol

 

Well last week I decided to dig into my slightly loose and always leaky front output on my FJ case. I pulled the driveshafts, the output unit on the t-case, and then the back half of the t-case. This allowed me to remove the front output shaft and bearings, and I immediately saw the culprit. I have a crack in my t-case, it goes right through the oiling groove and through the bearing pocket. This is undoubtedly the cause of both.







Now the fun part...when I got this case shipped to me from a salvage yard, I couldnt help but notice the bad surface condition of the cast aluminum housing vs the one from my taco. It appeared almost porous, not a nice smooth casting. Having spent $100 in shipping already, I figured, it had to pass Toyota QC to make it into an FJ so it should be fine. Well folks, I will state for the record this case cracked because of a poor casting. It appears as if the AL was too cool when injected in the mold. I zoomed in on surrounding areas inside the case to show just exactly what I mean...

These are the areas to the upper right and immediate left of the crack area in the second pic (zoomed in)





You can see porosity in the casting, and micro-cracks in the casting as well.

Now I need another FJ case and have to twin stick that one anf swap them out. PITA. I was really hoping for bad bearings on the output causing movement and leaky seal

Sure wish I could warranty what is clearly a mfg defect case.

 

That sucks!

 

If you want I can see if my friend that works at a salvage yard in Louisville has one

 

I'm pretty sure all the castings looks like that. Wish my J-shift tcases would fit your truck, I have like 3 spares in the garage now. I seem to bring one back every time I go to Denver.

 

My taco case was smooth inside and out Maybe this was the last one out of the ladle or min temp I dunno.

 

THanks, wish I would known an hour ago, lol. Just ordered one from a salvage yard. Should be here in a few days.

 

Lol any salvage yard things you need let me know haha

 

May be a stupid idea, but do you think I could add material to certain areas (like around the front and rear outputs) of the tcase to reinforce it? Should be getting a TIG welder in a few days...

 

I have the same dilemma... I'm thinking about buying an older 4Runner either a 1st or 2nd gen.
