Neon Rear Disc Brake Upgrade.
Posted: Wed Apr 01, 2009 9:47 am
Use this information at your own risk... I take no responsibility for any failures when doing this modification to your vehicle. You are fitting a part to the car that was not intended for it so the chance of some issue is always present.
Well, its officially in the works now. I just got off the phone with Mutual Auto Parts in MI and they are shipping me full setups for the 1996 Neon Sport Rear disc setup.
This is a Brake upgrade that I've seen done and heard about on the J-body forums for the LONGEST time... Actually to be more specific, here is their sticky thread title...
Now I have access to a machine shop to get my parts machined so this is easy for me, but may be a little more difficult for others.
Now I'm moving to this over my old rear Vette setup due to the fact that this has a Drum/rotor setup, so the parking brake is still a drum. Also all the wear parts are over the counter replacement parts, and the bolt pattern is the same as factory.
When my parts come in I'll post more info about it and I'll try to do a write up specific to our cars, BUT in the end the J-body write up is dead nuts on, since we share the same rear bearing and beam setup.
I will edit and fix this thread more and add the specific info as the project goes on, and I look through the write up I have. For now you can reply to this sticky, but in the end the write up will be locked, I'll keep this thread alive though.
**Update**
Brakes are installed... HOLY simple bolt on when you get the brackets done.
Lines and Adapters used
63011626ERL X2 3an to 7/16" Banjo 26" Hose
977522ERL x2 7/16 x24 Single Banjo Bolt (For Line to Caliper, I didn't have good ones)
989534ERL x2 Brake Adapter 3an to 10mm x 1.0 Female NOT Inverted Flare.
Double check all of your factory lines because you may not have the 10mm x 1.0 bubble flare like mine, my lines were all stock, but I do not know if they used that same line for all years. I know it applies to at least 94-96 since those all have the same rear lines.
The two modifications you need to make.
Grind down the top of the mounting bracket so the Neon bracket will sit low enough for the holes to line up. And I also cut the hook off the end of my e-brake cable so it fit in there better. I'm not sure if I had new pads if it would have been tighter, but after I did this I did end up having to adjust the cable in a good amount before it started to grab, so I really probably could have left it.... But I reused what e-brake pads came with the setup. I will also try to copy over the write up from the J-body board and start a new pinned topic to replace this one.
Brake fittings used 3AN to 10mm x 1.0 NON inverted flare... Uses factory GM bubble flared lines to a -3an line to attach my 26" -3an to 7/16 banjo. I also used these adapters up front do do my 20" lines for the big brake setup.
Fed line through rear subframe assy, nice clean install. I used 5 7/16 stainless washers to space the rotor out a tiny bit so it wouldn't touch the dust backing plate. Our bearings are slightly shorter than what the neon had there so you need to space it out about .080" This has also pushed my wheels out a good amounts, so I'll have to look at rolling my fenders some how and I'll have to be careful not to crack the paint on the inside edge... since once that happens it can start to flake off and could work its way around to the outside where its visible.
More updates on the way, I have a busy week with getting the race car ready for thursday so I wont be touching this again till the weekend.
