Thread: Brake question.. Maxima J30 vs 91-97g20 rear

Hi! i have rigth now a AWD b13 and im running on rear maxima 91 rear brake with custom brakets. And i read in other forums G20 91-96 rear brake its biguer than maxima?
Some one have an idea what size are both rear brakes ?? Im running ad22 in front and i will upgrade to z32 later..

p10 rear brakes are tiny. I would go with spec v brembo model rears that are 278mm.

I'm not sure if AWD B13 rear hubs are different than FWD, but I have maxima A32 rears on my FWD. The J30 and A32 calipers bolt up without the need for any custom brackets. Also there are OEM 4x100 rotors made specifically to use on the B chassis with maxima rears. They are 258mm vs the front AD22 @ 257mm.

According to rock auto the bore sizes for rear calipers per raybestos are as follows.

P10-1.34 inch = 34.036 millimeter

J30-1.35 inch = 34.29 millimeter

A32-1.33 inch = 33.782 millimeter

Actual FSM numbers may be different, but they're all pretty damn close to 34mm, and they all bolt up to our hubs. Just stick with what you have man. Are you using stock 234mm rotors with custom caliper brackets?

The pads are all the same dimensions as well. I think the differences are just the way the E-brake hooks up is a tiny bit different.

That wouldn't be quite a bolt on though would it? You'd need to get some rotors re-drilled to 4x100 right? Also, do the brackets bolt to our hubs?

Maybe on that i need modifications??

Very very very helpfull info!!! Thanks!!!

Awd and fwd are diferents brakets. Awd brakets are smaller i need to build a custom braket to make it more taller and use SE-R rears or J30.. Gti-r and b13awd are hard to find. For that reason i do the swap.
