EDIT: 87 9 bolt not 97! Typo!

Hello all,

I'm using a 3.42 posi disc 9 bolt rear from an 87 GTA in my street rod.

I have all new parts on it including calipers rotors, pads, etc, etc.

BUT as i have been piecing this together from different places, i don't have the brackets that bolt to the caliper, the lever with the counterweight that moves, or the spring between them, to operate the parking brakes.

From what i read, i can't do a brake upgrade to a different type because i'm going to be using 15" wheels, and i know this 3rd gen pre-89 brake setup fits in 15's as that's what i have on the project to move it around.

Message or email me here, or cortcomp at gmail dot com...much appreciated!

 

i just bought a pass side rear caliper from napa, and it came assembled with the counter weight and spring. the iron calipers or delco moraine def fit a 15 in rim.

 

Unfortunately i bought these so long ago that i can't return them, and they're new and didn't come with parking brake gear. These are iron calipers and fit, i don't know which car the delco moraine fit, or what year. I see a lot of guys here upgrade to the 89 rear disc brakes, but i don't think the larger aluminum PBR or whatever calipers will fit in my 15s. I'd also hate to spend more money on a disc conversion kit when all i need are the 2 levers, brackets and springs, when i think this 87 disc setup will work great for me, especially with all being new.

 

contacts hawks. tell them what you need. thats who i got my 9 bolt thru. Im sure that they have a junk one you can get parts from. ask about a tgo discount.

not a 100% sure but 85-88 got the iron calipers. 89- up got the pbr's. someone will jump in with the exact info.

ive read on here how bad the iron calipers are. i personally have had great luck with them. i went with a ceramic pad and new cross drilled rotors when i put the rear in.

 

if you use the 93-7 aluminum caliper you may get it to fit w/out sanding fins.
I use them with 15x8 weld wheels on my stock rotor 11.7rotor 89 formula.
I just had to sand the fins a very lil bit for clearance.
ditch those iron calipers. kinda poopy

 

Who is this hawks you speak of? EDIT: Found them and emailed them, thanks!

If i didn't have all new everything, i likely would buy new parts and upgrade, but i hate to do that since i also need to drop some cash in changing the only not new parts: center section. it'll be 500+ for new cones, bearings, etc, etc. but i want to do it right and be done the first time.

Also, most street rods are running rear drum for cheapness or simplicity, i would think these disc would stop better than most basic S-10 drums or what not. Plus, with an adjustable proportioning valve, i can put the pressure to the calipers if they don't perform how i want. I'm going to try these out first.

But hey, if they do suck that bad, i can upgrade and sell my like new parts to someone who wants all new iron brakes for a deal right?

 

82-88 for the iron Delco-Moraine calipers.

Thanks for the info, have several emails out to people, we'll see what comes back :-)

 

Still no luck, still looking. Most i've found is an upgrade kit to newer brakes, but all used so i'd have to buy new anways, don't want used on this project.

 

i can half-way help you out. I have 1, spring, bracket, torx-head bolt.

 

Hey, that's a start! I thing i found another spring in my parts cache too, i can compare it to yours when i get it! With the bolt, i can measure what it is and find another. I'll pm you.

 

Tentatively have all the parts i need! Will post again if not, but thank you everyone here that helped!
