87 CSX Rear Rotors

[Frank]

Where do I find them? I need to replace my rear brakes and rotors in the worse way and cannot find the rotors at all.

Thanks!

Talking out loud here.. are they the same as an 87/88 disc brake setup or something totally one-of created by the Shelby conversion?

[krut]

I think the csx rear discs are different than the Shelby z (Solid and vented) rear discs. I remember looking for them for a friend a few years back and it turns out they are specific to that vehicle for those years.(Prototype design?) If I remember correctly, the easiest route is to swap to the daytona rear disc setup, and we got the rotors turned as a stop gap.

I think your only chance will be the dealer

i might have a new set of rear shoes still in the box somewhere i can look for it, if that helps you. i'll sell'em cheap if i still got them

On my CSX they are right behind the back wheels. Once you get the wheels off you should see them.

I remember reading something many years ago about neon rear rotors being a possible replacement, has anyone tried them?

[cordes]

To answer the question at hand, my rotors are usually sandwiched between two friction type pieces that are hidden behind a hydraulic press type of thing.


IIRC Rich Bryant was the one behind the possible Neon replacement stuff.

I would avoid the 87 or 88 rears and change them to either the 89-94 non vented rotor brakess or 2Gen neon rear brakes. Overall it will be cheaper in the long run (and probably the short run too).

The 1G neon brakes can also work but they have a stamped steel backing plate that is heavier and can get bent up, etc.

If you use the Neon rear brakes you will have to:

1) Enlarge the Center hole for the axle stub (the neon stub is smaller but the bolt holes will line up)
2) Grind the top rear corners of your axle down so that they clear the Neon Ebrake connection.

There is a thread somewhere showing it.

I chose to use '89-94 non vented backing plates with a 85-87 rear drum hub. This allows me to use the slightly taller Neon rotors with the 89-94 backing plates due to the slightly deeper spacing of the rear drum hub... I find the 89-94 non vented brakes common enough to avoid the machine work to adapt the Neon rears. It still lets me run whatever Neon/SRT4 rotor I want and gives me the Neon/SRT4 caliper options on a part that doesn't wear out and just fits. If you can't find the 89-94 stuff then the Neon adaptation isn't that bad.

If you want more rear brakes then you can just use Dynasty/Intrepid/SRT4 36mm rotors instead of the non vented or Neon 34mm calipers. I don't see a benefit from going with the vented rotors which are going to become harder to find and weigh a lot more. There is a KC article about this.

Here is an article with 2G neon rear brakes isntalled but it doesn't show the grinding for the hub:

Assuming the '87 rears are the same as the '88 CSX, I got mine at Napa for an '89 Shadow with rear discs. Best I can tell, the CSX rear brakes were prototypes for the '89-up Dodge cars.

Good point, if they have the internal rear drum parking brake then they are the same as the 89+ and all is good.

If they have the weird parking brake cable connection to a lever on the calipers then you are better off upgrading to the newer style IMO. It is much better to be able to run neon calipers and rotors which are available and any parts store if anything fails. The 87 rear brakes used to be a challenge to find at times 10 years ago.

The odd '87/'88 brakes with the lever on the caliper were found on the Shelby Z Daytonas. The '87/'88 Shelby cars were a completely different set up from the '87/'88 Dodge cars.

Yea I forgot about that until Adam pointed it out. I think they are just '89 brakes.

In which case the KC article should apply: http://www.turbo-mopar.com/forums/kn...-Brake-Options

Wow... i like to think I am pretty good at sarcasm. You have humbled me.

The exception is the mounting hardware for the calipers. The CSX used the same bolts and sliders as the older front brakes; the '89-up Dodges upgraded to the better design.

[Frank]

I will give 89 Shadow rear rotors a try then based on what I am reading.

[Frank]

So the 89 calipers worked. Thanks!

Now for another hard question. I need to replace two caliper pins. Looking at RockAuto under 87 Shadow, there is a lot of caliper pins to choose from. I know the DORMAN Part # 13894 are a bit too short and have the wrong threads. Suggestions?

Thanks!
Frank

[supercrackerbox]

Hmmm. On mine, the pins are similar style to the front pins used on older cars, but now that you mention it I do think they were different threads. Rock Auto lists a bunch of options, but the only ones I see that specify rear calipers besides those Dormans don't have a picture and sound like the later style setup which I don't think will thread into your backing plate. You may have to take your old ones into a parts store and match them up. Shoot for a store where they have and know how to read parts catalogs; I've a feeling the computers might not get you too far.
