I installed a Strange 12 bolt that originally came out of a 4thgen into my 92. My car originally had drum brakes, and new rear end is set up for Lt1 rear disc brakes. What I need to do is connect the calipers to the T fitting from my old brake system. I was planning on using my old hard lines that went to the wheel cylinders as a guide. I can buy brake line for the parts store, and re-use my old fittings at the T, but from there, I dont know what I need to do. On the other end of the hard steel line, I need a rubber hose with a banjo fitting on one end and a threaded fitting on the other. Do any of you happen to know the size/thread/type of the fittings on my old drum brakes? There is a hydraulic hose manufacturer close to where I work, and they can make the rubber hose for me as along as I know what size fittings the hose needs. I REALLY need to get the rear brakes working here, pleeeeaaaasee help me

I did this on my 91z28. I put a 4th gen disc rear in place of the old drum rear i had. The 4th gen rear already had the lines on it and I just connected them at the T fitting. Your car will have 1 brake line coming from the front. You should try going to the dealer and getting new replacemnt lines for the 10 bolt rear for the 4th gens. They will come pre bent and already have the proper banjo fittings on the ends. You just got to get them to thread into the T fitting and the calipers. Does this help you

I ended up going to dealer for the rubber lines that go from the caliper to the hard steel line, then I bent my own lines and attached them to the T. I used the wrong flare, but it will work for a little while (I'm not even driving the car yet, just moving it up and down the driveway, lol). I'll eventually goto a junkyard and pick up some steel lines that are bent correctly, but for now, these will do. I was going to pick up the steel lines at the dealer as well, but the guiy said they dont come pre bent, just the correct length with fittings.. what kind of crap is that?!?

Pre bent hard lines are not available from GM.

Wrong... I got pre bent fuel lines for my 91z28 and also got a pre bent brake line as well. they fit like a glove too

Once again I stand corrected. Sorry!

hey Scott_92RS did you put a proportioning valve off you master or what did you do to power up your new rear discs

Scott_92RS

For right now, I'm just using the stock drum pop. valve, but I will change to a Wilwood adjustable one soon.

I am still using the stock drum style valve on my z with no braking problems what so ever.

Scott_92RS

Thats good to hear. If it turns out that my brakes work fine with the stock valve, I'll just keep in in there till I upgrade the fronts.
