Thread: OEM B13 rear brake upgrade

I have a set of junkyard P10 calipers, the big NX rear rotors with pads/hardware. Also a 93 (I think) Altima master cylinder. Is this is pretty much everything I'll need?

oops... Car already has AD22s (doesn't everybody ) with an aging set of metal masters and 4 ss lines .

What kind of fluid do you guys run? I just have some off the shelf Valvoline synthetic stuff.

hmmmm i think im guna have to look into this also

So is it necessary to have anything else for this to balance the front bias out? I keep hearing about replacing the proportioning valve but I hear differing things.

isn't the valve built into the master cylinder itself?

Actually the valves are screwed in to the MC. They can be unscrewed and replaced. The only thing is that there are two different manufacturer's of MC's and the PV's do not swap from one to the other....

There is a brake thread that talks about this in great detail and even lists the PV value's for each MC.

The proportioning valves that screw in are both for the(left/right) rear brakes. IF you have ABS you'll probably want the proportioning valve off the firewall of an NX 2000 with ABS.

No I don't have ABS. I just got the MC from a 1993 non-abs Altima. I'll go looka again. I hate the extra pedal travel you get from just running AD22s.

There is a devie on the firewall. I thought that was my proportioning valve.

to do the p10 upgrade i think you'll need the custom steel brackets as well

Bump so nobody knows if a MC off a 93 non/abs Altima will fit? I figured the earlier model be the right fit. No ABS on either.

Give Greg V a call. He helped me out with my rear brake upgrade. I'm not sure what year Altima you want the MC from, but he should know.

Also, it sounds like you have everything you need if the MC turns out to be the right one.

As for fluid, I use Motul RBF-600 and it's considered one of, if not the best fluid to run. It can be hard to find so order online or at a local dirt bike/ATV place. I would buy two bottles to flush the entire system. It can be done with one, but it's best to have extra. (I remember way back when I swapped fluids for the first time. I asked around and the best answer for how much fluid the system takes was 3 liters or something insane. I bought 8 bottles of this stuff and still have 5 of them left after 5 years. )
