Ok so i have been looking and thinking about doing a alero IRS or Neon Rear disks and i have some questions
Is there anybody that sells an adjustable proportioning valve for our 3rd gen cavaliers?
Is there any modding you can do to the junksion block to make this work such as a factory peice?
most people with the neon setup do not run a proportioning valve IIRC.
I have wilwoods on back and i dont even run a proportioning valve, and i have no problems.

Ok, does your back brakes over power your fronts?
and if i added a proportioning valve would that affect the (ABS)????
no my back brakes do not over power anything...the fronts still work great, the backs are nice...disk brakes with an internal drum ebrake.
The Neon discs are 10.6 inches in diameter where the factory fronts are 10.
Doing the NWF front swap would probably be the best proportioning valve you could get.

Good reading but read through all of the pages for important updates.

Not needed. I didn't have any issues when I had the SSBC brakes on the rears and stock brakes up front

I removed my ABS, and run a distribution block, combined with an adjustable proportioning valve. I can fine tune my brakes.
Do it right, you dont want drum brake pressure going to a disk brake setup. Disk need more pressure to work correctly!

Did you even try it with you ABS?? and thats exactly what i was thinking about doing when doing the swap!!!
your the man that really unstood what i was trying to get at here and also answered my Q to the best!! Thank you!!!
the proportion for running the neon rear is correct, the neons with rear discs run the same 70/30 that the cavaliers do. what you do need to address is the residual pressure valves that are inline with the rear brakes, they are the cylinders located roughly under the back seat, 1 for each brake line.
These hold 10psi pressure on the factory rear drums. Wilwood makes universal ones relatively cheap, you will need the 2psi ones for rear discs. personally, i just took them out altogether, but I always suggest doing as i say, not as i do.

thank you thats a big help and a nice thing to know thank you!!!
I didnt even notice that our cars were equipped with RPV for the rear. Thats usually for cars where the master cylinder is lower that the actuall brakes.
Im going to have to check for that and see what I need to do.
If I remember I will post pics of my distribution block.
phil thanks for the photo did you mess with the valve's under the rear seat?? and do you have more pic's??
dumb question .. could i use any other set from a different card other than the neon ? im talkin about disk and caliper support ..

wait you just confused me - When I bought the kit from your GP you told me that althought you originally fought for the RPVs, you have come to realize that they don't do much. Are you back on the other side of the fence saying that they should be installed?

well I doubt it was MY gp....Im not the one that does the kits, I believe that is Joshua IIRC.
I am giving my expirience with the residual pressure valves, I origionally left them in, but could feel the brakes dragging, so took them out. I always recomend doing the job the 100% correct way, which would be to get the proper RPV's in the system.

Oops my mistake - I was confusing u with Joshua. Sorry sorry sorry....
my car didn't have the rpv's and my neon srt4 swap works great.
my big brakes work great and so dose the neons we put on my buddies...knock on wood...we just bolted up and went.....
