2004 Nissan Frontier brakes

I went to an online auto parts store

i looked up the booster for each vehicle you listed (i had to "throw in" an engine size for the xterra)

each one showed two results

only one was "common" for both rigs

the other was not

this one also stated "rwd" (so it may not work for you)

i went back and looked at the others they are for "4wd"

i screenshot it at the bottom (below)

you might wanna re-check me at a different auto store site

lemme know if the store I showed is one available to you

i may can aid you in a heck of a deal

the one you need is $125 w/ $55 core (which you will get back when you turn in the old one) how's $40 off of the original $125 sound?

I screenshot the other (see 2nd pic)

personally, unless this booster you seek is sorta new, i'd opt for a new or re-manufactured one, this one has a lifetime warranty. This is your brakes, sorta a function your life will depend upon!

Lemme know if you want me to show you how to save $40 at this store (i save all of the time!)
