Has anyone done this conversion? My car already had the brakes installed but the E-brake setup is gutted. I figure I can find the parts for the calipers but was told the '81 E brake cables aren't the useable in this. What should be used? I read in some other posts its necessary to have this functioning for brake adjustment...thanks

I have a friend with a 72 Firebird and we installed an 81 T/A disc brake rear end with no problems. We took all of the e-brake parts off of the 81 and it all bolted up.

You are correct about needing the e-brake attached. The mechanism also takes slack up from brake pad wear and if you don't have the e-brake stuff installed, the pads will get loose.

What do you mean that the ebrake setup is gutted? Do you mean the cables are gone? You are right, you cannot use the stock ebrake cables with rear disks without extensive work. You just need some cables for rear disks. As gheatly said, the ebrake keeps the pads adjusted right or eventually the rear disks will stop working. Some people leave the ebrake disconnected and just manually adjust them once a month or so.

Good luck,

Thanks for the help! I looked at a diagram of the rear discs and by gutted I mean anything to do with setting the ebrake is gone...basically a rotor, caliper and brake pad back there, no cables or any of that smaller "stuff" it attaches too. I apologize for my poor writing skills, I meant do the '81 ebrake cables (intermediate, passenger, driver side) work on the '70? By your answers, I think they do, once I get a caliper with all the pieces in it! Thanks again for the help.

You definitely want to grab all of the e-brake stuff off of the 81. New calipers won't come with the arms that attach to the cable and caliper. If those are gone, good luck.
