Yep, you got it...you want big, you got big. Based around the P10 rear calipers.


Okay, like its stated this is a Rear BABK for the B13 based on the P10 calipers. Why the P10 calipers you ask...well...

1) Its what i have
2) They are cheap
3) They have a shorter torque member compared to the maxima rears making this kit possible
4) They utilize the same e-brake connection style so you keep your stock e-brake intact, and lastly
5) They have the same piston size as the maxima caliper so moving to a much larger rotor yields a greater rotational torque. (10" maxima rotor vs the 11.4" one here)

So yeah, not too much to say about this other than it kicks major ass...couple this with the AD22's or other Front BABK's and youll have some serious stopping power. I dont know if a larger MC will be absolutely necessary but probably recomended.

The rotor in question is an off the shelf rotor that is redrilled for the 4x100 bolt pattern, 10mm thick so a tad thicker than your stock rotor too (9mm)

Install is pretty straight foward, minor modifications are needed on the caliper, but nothing a grinder/file cant handle... a complete writeup on installation is here, this is the writeup for the P10, but the B13 is identical.

How much you ask?

-The complete kit minus calipers will be $250 shipped, and that includes modified rotors redrilled for the 4x100 bolt pattern. There will be a few weeks wait if you choose this route, i have to get the rotors sent to me, then modify them.

-Just the dogbones and hardware will be $150 shipped and ill give you the info you need to purchase the correct rear rotor, you will have to drill in the correct bolt pattern. I can ship this setup rather quickly, right now ill have two sets ready to go.

I highly suggest buying used P10 calipers for cheap and rebuilding them for the most cost effective solution to this.

Hope you enjoy!

Can this be made to use Maxima rear calipers?

nope, the maxima calipers have a taller torque member, hence the reason I used P10 ones more room to create the correct offset with the dogbone.... Besides the Maxima and P10 calipers use the same brake pads and have the same piston bore....

Technically speaking they are the same caliper with the exception of the torque member....

If your frugal enough, you can find P10 rear calipers thru car-part.com for about $40-$50 a set + shipping....drop another $20 on a rebuild kit and your good as gold.

Thanks for the clarification.

If I didn't just get Maxima rears, I would be all over this. Great product Pat!

is that rotor bigger than the 95-99 maxima rear rotor?

I know, I know. But they are already bolted up and bled. If I decide to upgrade again, I'll run this setup. No doubt.

Yahnozha

yes, by 1/2" or so in diameter....

FastNX

Can you clarify what you mean by 'shorter torque member'?

The torque member is the solid portion of the caliper...the maxima one is taller than the P10 one so if you bolt them to the same place, the maxima one will sit further out from the centerline of the hub...I guess thats the best way to describe it.

U12BBDreamer06

say if i had 1.6 drums in the back of my 98 b14 and i wanted your set is it possible?? I know i would need a better MC and maybe new brake lines for the rear but would everything else be okay?

Yahnozha

if you have a 1.6 with the drums, this wont work for you. The 1.6 has an entirely different rear spindle. Youll have to source rear spindles from an s-er for this to bolt up. Plus the B14 is different as well.

FastNX

So basically if you used the Maxima rear calipers, the holes in the torque member would be so close together (they may even overlap) the rotor would have to be bigger or the kit would not be possible.

I am wondering whether this has an advantage over the Maxima rears when using AD22s. I have a race car with 225 RA-1s, altered suspension geometry and 600# front springs. I know I need more rear bias and more rear heat capacity, I'm not sure if it is worth it to do this over the Maxima setup.

Yahnozha

exactly....unless i had a freak maxima caliper

As for pressure, they will be the same bias, like I said before, the P10 caliper has an identical bore and pad that the maxima one has...using this vs. the maxima upgrade your talking a lot more rotational torque applied to the rotor due to the larger diameter of rotor.

Torque = raduis x force

The force will stay constant between the two, and with a larger radius, youll have more torque applied. On the heat factor, these are much more substantial, so youll have more mass to dissapate heat with.

clear b14 rims, i would imagine so.. dammit i just did the maxima upgrade no too long ago...

not sure if they would clear B14 stockers, unless they are 15"s

what year altima master cylinder would be best to use with this?
