I got a noob question. I have the q45 complete brake conversion, which I bought used locally. But, I was wondering, can I use z32 calipers, with the q45 rotors? I'm thinking of picking me up some z32 aluminum calipers, just for that extra stopping power, and brake pad selection. Will this work?

OptionZero

the difference in stopping power is minimal, you might as well buy parts meant to work together

you're trying to re-invent the wheel into something that rolls no better

if u want q45 brakes, use the proper rotors

if u want 3z brakes, sell your q45 shit and get 3z calipers and rotors

Did you ever get that bleeder out? Try a propane torch if ya didnt. Along with generous use of PB blaster and aforementioned vise-grips. You'll be golden

speedgod^s13

The reason I asked, is that I thought q45 and 3z rotors, were the same size?

OptionZero

don't be cheap or lazy or stupid

just buy the right rotors

hondanissan

btw, altima rotors are slightly a bit thinner than the q45s.

SoguRacing

did my q45 brake conversion 2 days ago. redrilled the rotors/resurfaced them got new pads and all costs about 60 bucks. haha 1/2 off at the junkyard and used the school lathe. good cheap upgrade for the budget peeps.

Q45 and the 26mm 300zx rotors are the same. The 30mm 300zx rotors are difference because of the thickness. All 3 rotors are 11 inch diameter.

maybe a noob quest but ive been lookin all over for info...well i wondering for those who did the z32 brake conversion i headr that the travel of the ebrake is way more than wanted even when adjusted to maximum amount for least travel and how is brake bias and brake pedal travel....ive been wantin to do the z32 upgrade but the q45 just seems alot chepper and work just as good or better with brake bias and ebrake.....also with the conversion lines(being causing the ebrake to travel alot) and the rear upright alot of people have problems iwht them... sorry for so long i just got so many questions and need answers.

also can you shed some light on the rear upgrade with z32 and q45 wether being bolt and what is needed or removed/replaced when doing the rear between the two z32/q45. i have the z32 rotors fr/rear but i dont want sh... brake bias and i dont want to spend alot of extra$ to make the z32 work...and yes i have looked around alot thats why i got alot of questions

Q45's will yield you more brake torque = more braking power thank Z32 FYI but better pad selection for Z32 ofcourse. But with all the extra brake torque gained by just upgrading to either of these brakes, unless your tracking the vehicle or something even el cheapo pads will be fine.

+1 for q brakes.. but i installed the pistons myself. not very hard.

I'd like to see what they're like with a z32 bmc though, because i can still put the pedal to the floor if i really push. of course, the brakes are locked up way before then anyway..


also, my friend with z32 brakes and i traded cars for a bit and test drove them.. neither of us could tell the difference..

ka-turbo

so basically the q45 is cheaper and better it being bolt right up but do you need the brake caliper shoe (i think thats what it is not (not the caliper itself right)) but what bout the bias and cost of parts? copmared to each other. and with people who brake pedal travel did you ahve that before you cahnged the rotor and calipers because i know alot of ppl need to adjust their bmc. and what all is needed for the rear swap for q45 or they just bolt on like ive been hearing. it sucks i just bought these rotors from 88rotors but now i want to buy the q45 rotors so im stuck on which will be less work, easiest, and least expenssive and how will they feal with braking and brake bias

Not the same. Early Q45 rotors are 280x28mm. While the z32 came in 280x26mm and 280x30mm

what kind of pads to you guys recommend? I got some nice d/s rotors for the q45 brakes and I don't want pads that will eat rotors. Is it true that you need special pads for d/s rotors? I'm not a noob to cars, but products lol.

SoguRacing

You can't get any cheaper that doing the q45 upgrade. come on guys. junkyard at 50% off days..its like a 90 upgrade with good pads. I've actually got J30 calipers but they're the same thing (essentially the same thing). I've got a couple BM44 BMC's for sale that's the 15/16 size for 60 bucks. q45 rule!!!

I run q45 w/ Hawk HPS HB415F583 Pads, love em.

Socal/Hesperia:

These guys CNCed my rotors to 4lug; brought them a stock s13 rotor too, so they could get the measurements. Mc Custom Products
Dunno what they charge, because they did it free for me ( hommie hookups). Anyways if you want something done perfect, there ya go.

P.S. Their shop moved, dunno if the website is updated, but its RIGHT behind OSR shop/tuner guys now.

Hey guys, the original thread/conversation has been over a few months now (check the OP dates)


To the new post'r who resurected this.

Q45 brake upgrade and 5-lug Swap are two seperate things.

Seach for 5-lug swap and you get all the info you need. It can be as easy as a set of 5-lug hubs (purchased as a kit - Ichiba & Circuit Sports are most common choices)

Once you have 5-lug conversion, you may want to consider this Q45 brake upgrade. Makes a great combo.

Hope that helps. Search around or PM me if you need any details.

spacedog

yes, and q45 brakes will fit under steelies aswell.

FusionR240sx

didn't see that... just saw that the thread was on top of the tech so i posted my baaaaad

did the op say also that he did all 4 rotors with calipers i havnt really been able to find any straight answer on the rear calipers for q45/j30 calipers installation

I think I paid $50 or so to the junkyard for my Q45 rotors and calipers. I actually had the parts for over a year without installing them, since I was waiting until I got a drill press to modify the rotors to 4-lug. Eventually I got fed up and bought a set of aftermarket rotors from eBay for $100 and had the dust shield cut off and the new parts on in 2 hours.
Rather than powdercoating, I just bought a cheap can of caliper paint from Autozone
and gave them 2 coats.

theslows13

ohhhh boy, is that yellow ever such a classy color! woooweee.


seriously dude? and you painted the small boots and rubber endcaps too...

flawlessflo3190

can i use stock 5 lug s14 rotors with q45 brakes?

The Inflicted

Nope, diameter is too small and the stock rotors may be too thin as well.
There are some Altima rotors that are rumored to work, but I'm not sure which years. Try Google.
