Write up for J30 brake upgrade.

[AZhitman]

Only thing I need to convert it to an Article is I need the pics loaded in PhotoGallery (not on PhotoBucket).

If Photobucket takes a crap, bye-bye pics.

[SeVa-S13]

If Wei (Anumeric) doesn't do it, I'll upload 'em when I get home.

[anumeric]

I went ahead and uploaded them into the photogallery and changed the links accordingly, so no more photobucket worries. Its all yours Greg do as you wish.

thanksWei

Are you saying that the rotors were too hot and that was what was causing your brake fade?

Are you saying to get cross drilled or slotted rotors for heat dissipation?

The reason the rotors are slotted or drilled is because back in the day when you braked hard a gas used to build up and having them slotted or drilled was a good way to get the gases out and improve braking.

I suppose they help with cooling but that's not why they were originally made for.

Bum.

So how did you adjust to fit the new calipers on? Did I miss something here?

No adjustment needed, you just hafta use the j30 calipers brackets with the j30 calipers, as the j30 calipers wont mount on the s13 caliper brackets. Also the j30 pads are bigger so they wont fit into the slots on the s13 bracket.

I think he misunderstood or something. I'm pretty sure S13/S14/J30/Q45/Z32/R32 and evern some Maximas have interchangeable calipers, as in they'll all bolt up to eachother's mounting brackets.

Nah no misunderstanding lol. Some of the calipers may be interchangable with other brackets, like the s13/s14, or the j30/q45. But using the j30 and q45 calipers on the s13 brackets just won't work. For example the j30/q45 pads are bigger and since they sit on the brackets they wont work on the s13 brackets which are fitted for the smaller s13 pads. And for the z32/r32 calipers I don't know for sure if you need their brackets or not, since their pads are fitted/seated on the inside of the calipers with pins that slide through the pads themselves.

awesome write up and ballsy drilling. you may wanna remove some of those " " marks. kinda threw me off when reading it. otherwise awesome stuff man... approx pick and pull price on that setup?

Thanks for the complement. I pick up these goodies along with abunch of stuff for my CA and s14 manual seatbelt for 27 bucks. Granted it was half off weekend but still I was stoked. But if your heading to pick and pull this weekend is half off again! may 20-21 dont miss out.

Excellent write-up!

How do the new brakes feel?

Any difference in stopping power/distance? I'm sure there is, but how significant, that is the question

Thanks, I definately notice a good difference with the stopping power and responsiveness. I couldn't give you precise distances but yesterday this lady decided to pull out right in front of me. I just barely missed hitting her, if I still had the stock s13 front brakes I know for sure I would have rear ended her.

very nice write up.. i might just do this instead of the z32..

[shiaokaz]

Good job..thanks for the write up.

driling the rotors like that is fine. the center hole centers the rotor so there is no way of causing vibration with crooked drilling. if the holes are off, the rotor won't fit on. if that's the case, just make them bigger. the lugnut holes are just a place for the lugs to go.

even if you screw the holes up royaly, the original hole and wheel clamping force will be enough to keep the rotor from rotating on the hub.

[ADiamond75]

I did the Q45 on my s14 ... and it was cakewalk to install. The Q45 and J30 brakes are the same, only small difference between them is the q45's have a space for a sensor that can be hooked up to set off the brake light indicator on the dash when the pads wear down. As for breaking power, I have driven the 300z brake upgrades and the Q45/j30 upgrade honestly feels more balanced to me.

Oh and, no more brake fade. I used to get it alot and changed rotors three times and tried four different types of pads.

Ironically, when one of my callipers locked up it was cheaper to buy loaded q45 callipers from autozone then to replace the stock 240 calliper. I managed to do the entire swap including braded lines for $220

That's a very interesting point. I never thought about it that way. The brake rotor is not at all lug-centric like the wheels(technically hub centric, but also use centering via tapered lug seats), and is centered by the hub.

Edit: This is of course assuming that the Z hub bore is 63mm like the s chassis bore. Is this correct?

yep. like a lot of stuff on nissans, the same across the board.

sorry for bringing up a dead thread. i already have 5 lugs on my s14 so would everything just bolt right up Caliper, rotors? and my own brake lines? Thanks guys

ZOOOOMMBBIIIEE BUMP!



short answer, yes

easier than you think

Thanks guys. i jsut wanted to know because some lady blew her motor and she sold me the entire car for $150 its a 96 J30. is there any other useful stuff i can pull form this thing beside swapping brakes and rotors?

[Chris28]

Vlsd and axles. Rear 5 lug hubs will bolt on, but you're already 5 lug. Sell them to an s13 owner. The injectors are 370cc's. Sell them to someone going ka-t or to someone with an SR that needs injectors. After that sell it to a junkyard and make some profit.

[bersh240]

dont forget the maf sensor. front hubs can be modded to work.the speakers are nice.

[ILoveMyRHS13]

Rear 5 lug hubs will bolt on

Indeed. Take the whole rear knuckles and use the ebrake and everything.

i think this thread disrupted the space time continuum

[anumeric]

Wow can't believe this thread is back. But yes grab the maf as well, J30's came with n60, n62, and e60's.

Anybody know if you could bolt the entire subframe up to an S14?

[locoluna825]

^^^ Ive asked this question before. Noone could answer me either. But ive looked at a j30 subframe in person and it looks xtremly similar to the 240's subframe. Ive even searched on courtesy nissan and found out the s14 and j30 had the same part number. A friend of mine wants a VLSD so two of my friends and I are going to the junk yard this week (maybe friday) to do some measuring between a s13 there and a j30 to see if it would bolt on.

[sx moneypit]

It seems like that would be the way to go.You would get the LSD and the bigger brakes. It would be plug and play.Keep us posted as to what you find out.Thanks
