Hi, i have found a used set of rear disk brake for my 89 omni.

After have checked all thing a couple of time...Do i have to cancel the parking brake?...There no place to put the wire on...


Any suggestion?

Thank you

What kind of car did the rear disc setup come from?
If you get the right setup you keep the parking brake. You need the non-ventilated rear disk with the internal drum setup for the parking brake.
i used vented rears from a IROC daytona. everything bolts right up. i kept the e brake . i compared the non-vented setup and it had a wedge style e brake. this is the one that you dont want to use. Make sure you use the prop valve from the same car that the rear disc setup came from or you will have issues.

There are actually two varieties of rear disc brakes with the solid rear rotor. The first ('87-'88) used a wedge/screw type e-brake. The later style ('89-'9x) used an internal parking brake drum very similar to the rear vented 11" rotor setup.

One thing to note is that the #d Shelby cars had a pre-production rear disc brake setup that uses the internal parking brake drum. My Shelby Lancer rear discs are very similar to the rear disc setup that was on my '89 Shadow ES. It is very different than the rear disc setup that an '87-'88 Shelby Z would have had.
I used 87-88 daytona rear discs and calipers..I even got the original e-brake cable from the omni to hook up to the calipers. It took some mods but it turned out great. Everything just bolted right up. Only problem is the price of the new rear calipers($95.00 each cdn + $100.00 each for the cores). I'll try to get some pics. The other setup seemed to heavy...

this is awesome...... i had to high jack........ so my 88 csxt has the drum parking brake setup? to bad my ebrake still doesnt work. :bash: i havent had time to pull apart the rear to have a look. if i wanna go in somewhere and leave the car running lol i gotta find a nice level spot so it dont roll when i leave it in nuetral.

Holy crap dude, why don't you clean some of that stuff before you put it on. Here's my 11" vented GLHT rears before they went on. They look just as good on the car too! Powdercoated the caliper bracket, center part of the rotors, and all the misc stuff.
