How to upgrade your B14 brakes by raiding the Nissan parts bins
I will start by saying this "how to" specifically deals with 200sx SE-R's that start with factory rear discs. There is also a way to upgrade B14 rear drums to this same setup, but since I started with discs, the disc upgrade is what I'm covering. I'm not going to cover what came stock on your car check the brake thread for that info. I'm just focusing on how to swap to AD22 (NX2000) front brakes and A32 (Maxima) rear brake calipers with B15 SpecV Brembo package rear rotors.
I'd like to give a big THANKS to Mark @ OEM for allowing me the use of his lift and facilities for the day. If you do not feel confident in attempting this procedure after viewing this whole thread, PLEASE get help before going any further.
A quick peek at the difference between the stock rotors and the rotors used in this upgrade, top left is the stock rotor, bottom left is an AD22 rotor:
The AD22's also have significantly more thermal absorbing mass:
Stock front calipers on bottom vs AD22's on top:
First order of business is to remove your stock calipers and rotors. Starting in the front, first remove your wheels. Loosen the 12 mm bolt that attaches the brake line to the caliper. (It is much easier to loosen this while the caliper is still attached to your car. Next remove the 2 14 mm bolts that secure the caliper to the carrier bracket. Remove the brake line and secure it out of the way. I used a zip tie to the spring technique. Pull off your old caliper. Remove and discard your old brake pads. Next remove the 2 17 mm bolts that secure the carrier bracket to the hub. You can now remove the old rotor. With the caliper and rotor off you should see something like this:
That splash shield will have to come off before the NX rotor can go on. I used a hammer and chisel to get through the shield at the thinnest point and then bent it open wide enough to pull off the hub:
It should look like this when you get it off:
Now you can put the ad22 rotor on and reassemble in the opposite order of removal using the ad22 parts. Bracket with 17 mm bolts, then pads, then caliper with 14 mm bolts, then brake line to caliper with 12 mm bolt. Reassembled you should have this:
