Brake question
I picked up a 92 gxe yesterday and it needs brakes. So my question is my parts
car has all new breaks on it and is 4 wheel disc but the new car has front disc and rear drum, Will the rear discs bolt up to the new car. If so what all do I need
to change.

IIRC,you need to remove the whole rear strut/hub assembly from your parts car as one piece,swap it over,along with the parts car brake lines(drum brake lines will not mount up to the calipers)

but i forgot a critical thing in my original post,you also need to remove the e-brake cable assembly from your parts car/swap them over to your d-driver if you want to have a functioning E-brake..
(not really necessary imo if it's an automatic)

MC is the same for both cars without ABS... since the new car has drums, you obviously don't have ABS.. so just leave the MC alone.

are you sure the rear brakes need to be replaced? in my experience, the fronts wear out faster so you may just need to replace those. if they do need to be replaced you have to weigh your options: the work that goes into the rear brake swap will save you from having to buy parts for the drums but is it worth the extra work if you aren't concerned about the performance upgrade. your call...

read the instructions to find out how hard it is.
and no, I haven't done it before. that was only me laying under the car while Kaleb Broadhead (f/ Courtesy Nissan Parts) was shooting pictures.

Ok cool I need new rear struts anyway and the parts car has new kyb so might as well do it, next question the parts car has abs but my d driver dose not will that be ok since I don't need the master cylinder.

Go for it, its not that hard. I bought whole strut assemblies from someone here on the org. It was for ABS, but you can just leave the ABS cables unplugged. All I had to do was remove my rear seat, unbolt the struts, and I just put my current springs on the new strut assembly. Installed it in the car, and ran the new e-brake cable (realistically, I think you only need the ends of the cable that hooks up to the caliper, from the handle to that point, it's the same.) Took about a couple of hours. I did it because it's "supposed" to brake better, and for looks mainly. Disc/drum ftmfl.

My drums are f(_)cked completely. Don'd do squat when I engage the brake. I could easily spin the wheels by hand when the car was jacked up with the parking brake engaged. My parts car has all 4 disks. I didn't even think about it until now.

yup, this thread has convinced my to go to the JY this weekend with Ben to help him find some stuff but I will also pick up myself some VE rear strut assemblies so the year matches my car + bigger brakes IIRC 
Ah yes, sandblasting em at work once I get em or just wire brushing em with the drill for now
My rear brakes (drums Duh) keep needing adjustment cuz I only feel like my fronts are doing the work, rear ones arent locking much when slammed. Bla I might just do the swap this weekend since I saw a few VEs at the JY last time.

I have a question regarding a swap from rear drums to disks....does anyone know if the GXE's with rear drums have proportioning valves?
I was reading a car mag about people who convert rear drums to disks, and they were eating through pads and running times slower than what they should be. I guess something for some drum brake cars, called a proportioning valve, which alters the pressure going to the rear to prevent rear lockup. I guess that somehow the rear brakes always had pressure on them brcause of this proportioning valve and when they removed it their brakes has a more even feel and better stopping power overall. Is this a potential problem with our cars???

the master cylinder is the same for 3 gen maximas. the prop valve is internal to the master cylinder.. don't worry about the bias issues you've read about old school american iron as compared to ours. completely different system.
Bloo... all the 89-94 rear discs are the same size. the pads are the same size. the only difference is that the calipers have a different torque member between 89-90 and 91-94, presumably to make more room to get to the bolts in the later models for maintenance purposes.
If you want to go to a larger rear setup, use the Z31 turbo rear discs, 89-90 calipers, and 91+ torque members. it's a bolt on swap at that point but you have a 1" larger disc in the back. but don't waste your time on that unless you've done a front BBK.
