hey guys got a quick question here on brake lines and how they can be split or put together

I just helped a buddy do some work on his toyota. One of the things we did was swap his small factory rear axle with drums for a 8.6" gm with an auburn locker, 4.88s and disc brakes. Part of doing this swap over was the brake system. The toyota had independently run brake lines to each wheel whereas you know, the gm axle has one line running to it and splits at the axle. The toyota of course had wheel speed sensors on it but we will no longer be using these and will have them written out.


my question is...

Can i put a 'T' in there, connecting the two brake lines coming off the chasis to bring them to one line out to go to the axle? or would this create too much brake pressure on the rear and lock them up every time??


I know this is a blazer forum and I use it for 76 but I dont have any toyotas and dont feel like making an account for one measly question

Thanks All!!!
 
gm started using abs on solid rear at each wheel and also this got them using 2 line rear brake system with 2 hoses .

I would just look in to using 2 hose system for less complicated use.

but if the system is like I am thinking its 2 line master in to abs box were it was 4 line out from factory . so you could prob tee them together but this would be redundant .

you might need to remove the abs unit and replumb the system from master to axles for best / least problems . :dunno:
 
Yes, you can tee them together no problem as far as pressure goes. It will stay the same. It would be just like adding a larger diameter line. I don't know anything about how their anti-lock works but pressure won't double by adding a line that is working at the same pressure as the other one.
 
ive heard back and forth on it. curious your reasoning. trying to educate myself here

his motor doesnt have enough power to hurt that axle anyways.
my sierra has the same rear. I have more power, weigh more, and tow on mine with no issues

For starters the Toyota rear does not have cclips. Thats a huge deal in its own right. The toyota has more and better aftermarket support, removable third member, an easier housing to fab on for offroad beating, nearly the same size ring gear and if I recall it has stronger bearings. Also a stronger carrier.


The toy 8in was basically a rip off of the ford 9. Which we all know theres no 1/2ton axle out there that holds a candle to the ford 9s design.
 
im only using the housing and shafts
the housing is trussed now
using an auburn carrier and richmond gears and all new timken bearings and new seals as well as new cover for strength

and yea i agree about the c-clips. how does the yota rear end hold in the shafts? its not a FF? or at least not one like im used to. probably a stupid question...i know

oh ok. I wasnt aware they were as similar inside
 
At least with disk breaks, you wont loose an axle shaft if you brake one. And you removed imo the weak spot (spider gears) with the locker.

T is correct.

Toyota has axle retainer plates at the end of the housing and a pressed on bearing just like a 9in.

I mean obviously you already did it but its really a very lateral move for all the work you did.
