    I'm currently doing this, I had some old EF9 calipers kicking about, so I'm reconditioning them, and getting them machined down 3.2mm.

    Going to use EF9 discs/rotors too.

    The bracket will fit no problem (all hondas use the same bolt pattern) but if you don't machine them down then its not going to center the caliper on the rotor! You are going to be dragging a pad on the rotor.

    :? I'm confused.Aren't EF9 calipers just Civic 2WD calipers?

    EF9 discs are 262mm, same as EF8/DA6/EG6/EK4 and early spec DC2

    The other Civic 4g HB's have 242mm front brakes.

    The calipers aren't 262mm... the DISCs are 262mm.

    lol yeh i know, it was a typo
  • You guys said that I would need EX knuckles to get the 11.1" disk on our wagons, but EX's are hard to come by, so why not DA integra knuckles they should work just as well right? If not, why? I don't understand.

    DA's are a bit longer iirc

    the driveshafts are too.

    Explain a little more, I don't understand what you mean by longer?


    *edit*
    I also found a guy who used DX knuckles and was still able to have 11.1" brakes.
    Any reasons why this will not work with our wagons?

  • Marc_EE9Marc_EE9 Senior Wagonist
    when you guys say knuckles, you mean track rod ends?

    im going by the driveshafts being longer, so the TRE's would also need to be too? as theres generally a longer distance from the hub to the underside of the engine bay

    i could be wrong, im just thinking out loud
  • AHHH understood. What about that DIY on the link?

    yeah my brother is a wiz on the cnc @ his work and is making custom 1/8" adapter pates to sit on the hub behind the rotor so no need to machine caliper. will post pix when he is done
  • klumklum Senior Wagonist
    just got my 92-94 vigor calipers same bracket number and caliper number :D
    went to kragens bought my 93 ls rotors and 97 ITR pads
    about to find me a 12 pack of blue moon and get down this weekend im not sure if i wanna take the bracket to be machined or if i should jst try to grind it my self. hmm 8)
  • klumklum Senior Wagonist
    why do the brackets need to be machined?
    oh cuz the pads will drag? wont they just wear with time? ;)
  • klumklum Senior Wagonist
    main reason i woudlnt do the above 11" rotor thing is because the rotors have to be redrilled i just dont swing with more holes in a rotor for somereason. if im not comfortable with these 10" idk what will make me happy im usually content with stock brakes and low end torque heres a secret!
    i ride with the ebrake cable up one click- instant pedal response!

    let us know how it goes! i had this thought, but thought the lug nuts would be a bit short. they seem to be pretty short at the moment. so i guess this is why they machined the carrier rather than spacer behind the disc...

    To answer 88hybrid,klum & Marc_EE9.

    You can machine(milling) or grind.I read of 1 guy that ground.Seam to work for him.Just try to do it as parallel ,even & straight as possible.

    It is be possible to NOT machine,grind or use spacers by using thinner inner pads.This can be done by using junkyard pads(meaning used pads) or different types or brands of pads.Like I found that OEM pads are much thicker than aftrmkrt. Ceramic pads.This works fine as long as you keep a eye on the pads.

    The BAD of NOT machining(milling),grinding or using spacers from not so bad to worse:
    1)Inner pads will wearout way b4 outer pads.
    2)Inner pad may lock up to the rotor when u bolt it up unless you use a thinner pad.
    3)It may rub against the inner wheel.
    4)As the inner pad wears out .The metal portion of the inner pad will fall out of the caliper brkt. race & you CRASH :x :!:

    The BEST way is to use spacers.I don't like the milling (grinding)for several reasons.The milled caliper brkt mounting tabs become thinner making it weaker where it bolts to the knuckle & the part you just milled is also threaded.It's like using a thinner nut.That lack of Safety I don't want to play with.Using the spacers is only about $50-$100(usd) more than milling, includes the longer studs.Stud installation is fairly easy with minimal tools.

    For "Street & Show" milling is fine.That lack of Safety I don't want to play with.No hate mail please.You decide.
  • klumklum Senior Wagonist
    what kind of spacer do we use? just the regular wheel spacer?
  • SiWagonSiWagon Council Member
    Wheel spacers don't usually work 'cuz you need to grind down the O.D. to fit it under the rotor hat.There are usually too many holes in them to have any metal left after you grind it down.

    :idea: You can make your own.Depending on the caliper/rotor combo you'll need a 1/8-3/16" thick alum.You don't even need a tight fit for the spindle nut center.Most peeps used the 1/8" spacer.I had to use a 3/16"(4.7mm) spacer for even pad wear.

    I'm with you on the 4-lug thing.I went a step further & did the BIG Brake on the 9.5" rotors. :arrow: I could run 13" wheels.
  • Marc_EE9Marc_EE9 Senior Wagonist
    thanks SiWagon :D
    i certainly see your point. i dont think it will matter that much, and machining is the cheaper option. if i grind I can do it myself, im sure a fabricator wont charge much to mill it down 3.2mm

    spacers are about £10 for a pair, and for the hassle and ease of upgrade, im going to choose grinding. purely because if i need to change nuts, i may as well just get EF9 front hubs etc.

    just my input/thinking out loud.
  • klumklum Senior Wagonist
    si wagon im still not quite following you, where would you put the spacer?
  • The spacer would go between the rotor and the hub. The hub is what your wheel studs are pressed into. Instead of a spacer you could just put washers on before you install the rotor. You might have to get longer screws that bolt the rotor to the hub, the countersunk screws that are a pain to get off. Or you could just pay an automotive machine shop $20-30 to mill off the 1/8 of material and call it a day.

    My opinion would be to mill so you don't have to give up the strength in the wheel studs. If you worry about the bracket thickness after milling, measure the thickness of the the milled bracket and compare that to the thickness of the stock bracket on your wagon. Not much difference. I wouldn't grind the brackets, the pads need to contact the rotor at the same time or you lose your braking pressure, grinding is too sloppy. Completely unsafe in my book.

    To each his own, I say do it properly now so you don't have to worry about it later.
  • SiWagonSiWagon Council Member
    There is no loss of strength if you go with longer studs.Another way to look at the bracket issue is to imagine the bracket with 1/8-3/16" milled off.Doesn't look like much left.On top off that there's a lot less threads left too.Several other racers shared my view.This was confirmed when my machinist said he WOULD NOT recommend milling,when I originally asked him to mill the bracket.He does a lot of machining for racers."It's your brakes :!: ",he said.

    :arrow: Well...There you go you have both sides of the story.You make the call.

    On other cars I'd run wheel spacers,but NOT on the Civic.Even with a 1/8" wheel spacer it DOESN'T leave much threads engaged to the nut.Run longer studs with wider (hub or wheel)spacers.
  • klumklum Senior Wagonist
    im gunna go with the milling if i feel like its a bad idea ill go grab another set their all over the pick and pull
  • i am running a prelude/legend 11.1" brake upgrade on DA front knuckles. i shaved the inside of the 23T bracket coz i dont have access to a milling machine. it works just fine even with a few hard stopping braking. The wagon nose dived though coz its has massive front brakes. I may need to change the prop valve to 40-40 to even it out. Thats my 0.02 cents there.

    yeh, we do this upgrade on Civic's over here. they need about 2mm shaving off. or the better option is using MG ZR 160/ZS 180 front calipers - they bolt striaght onto EF9/EF8 hubs, with no mods needed

    do you have any pics of your brake upgrade ricefighter?
  • Marc_EE9Marc_EE9 Senior Wagonist
    17CL15VN ive found are twin pot Accord calipers... ?

    they still ok to use ?

    If they use the 23t bracket, I think it will work...

    im surre they will too, i need to go out and find some twins mine are single
