    Default anyone for a brake upgrade?

    Hi Guys,

    i am posting this a little early, but in the near future i am going to be upgrading the brakes on my 240K

    The Car currently has a set of upgraded front brakes which i am looking to sell (they were on the shell when i bought it). My car currently has C210 struts, but i do not think this makes a difference (i believe they were only swapped as the struts were height adjustable)

    The Calipers are Toyota Hilux with Honda accord discs. They fit under my 14" rims and according to the datsun 1600 guys, are a pretty good upgrade to the 240k ones!

    Not sure what they are worth, i guess around $350 for the calipers, pads and rotors? they will have to come off when the upgrade takes place, as i believe you need to remvoe the bearing to get the rotor off ( ) so i am not going to attempt to do it myself.

    anyone interested?

    If anyone is serious about a bigger upgrade, i am also going to be selling the parts i collected for a 300ZX/R31 front and rear upgrade:

    Pair of Nissan 300ZX Non-Turbo 4 piston Alluminimum 26mm calipers (paid $100)
    300ZX calipers powdercoated red ($100)
    set of 300ZX caliper seals (paid $170)

    Pair of Nissan R31 Pintara single pot calipers (paid $50)
    calipers powdercoated in red ($100)
    set of R31 caliper seals (paid $30)
    Set of R31 pintara rotors (paid $50)
    set of brand new Ferodo Extra Pads (payed $78)
    2x brand new DBA Slotted 616 rotors (bought for $260)

    looking for $270 for the 300ZX calipers and $450 for the rears, some work would be needed fitting the brakes, ie. brackets, front rotors and hand brake cables etc. they are all here, off the car etc. so if you want them you can have them!

    a bargain compared to what i am looking at now spending on brakes

    This is a pic of what the rear R31 brakes would look like (on a 1600, but very similar)

    They look good. I think Ray used R31 discs on the rear of his 2000GT and they worked well...

    from sizing it up it looks like the rears simply need to have the drums and backing plate removed, a mounting plate made up and welded to the frame and a handbrake cable customised.. if anyone is interested, i will seperate the R31 new rotors with the rest

    $250 for the rear DBA rotors (advertised on the R31 forums, so they could go quickly)
    $200 for the rest (i would need to dbl check the used disk thickness)

    maybe it would be worth going the Toyota/Honda fronts and the R31 rears?

    the Toyota calipers and honda disks are now being held for Lachlan.

    the other brakes are still for sale!

    the hilux four pots are a direct bolt up, like on the s30 struts?
    must you use the accord rotors or is it just if you desire vented?
    what year/model accord?
    anyone have dimensions or pics of rotors?

    Lachlan should, as he bought them from me (not sure if they are fitted yet?)

    they bolted up to late model 240k struts, though it is not clear what year the change was. my car has C210 coil overs, and they bolted straight up to those.

    pics of rotor, two posts up

    so the accord rotors (what year/model?) fit without mods, but except for being vented, and the install of 4-pots, all other measurements are the same? if so, then i won't really need detail pics/measurements

    aren't there 2 types of hi-lux 4-pots that fit the c110/s30 strut?

    it is probably best the get the rotor diametres off Lachlan, and then match them up with the right model ones from the DBA catalogue, i didn't do the mod myself, as the brakes came on the shell that i bought, though it doesn't seem to be much different to the mods that the Z guys do..

    I picked up a set of struts from a wreckers lying aound for my old 240k a few years back.

    They ere about 275mm ventilated disks. Made a huge difference.

    Same size disk as the early 300z. I believed they were out of a 1988 silouette skyline australian model.

    resurrection time ... if kent is still around? ... hey kent, does the r31/z32 combo require positive offset wheels? i ask because here 510 guys run s12/z32 combo, and that requires positive offset wheels

    Hi Matt,

    unfortunately i didn't actually get the R31/Z32 combo installed, so i can't really help.. i originally had the hilux/accord combo on the front (with steel wheels, not that it was ever on the road in this setup), which i then replaced with R34 GTT calipers and rotors with custom mounts.

    I still have the Z32 N/A calipers here though if anyone wants them.. and i also have 2 BNIB rear caliper mount to suit a DR30 (early models that used a bracket rather than being welded to the arm), which should fit straight up to the rear axle..

    Do you have a booster to go with that master? also what master/booster combo are you using?

    no, i am afraid not.. but it should work with the standard booster..

    i am using a 1" DR30 skyline master on mine (apparently pretty rare now).. and i "think" that the booster was a 10" R31 item (but it could have been a DR30 one too..)

    My std booster is the size of your fist and looks more like a clutch booster than a brake one. I'll look into getting a DR30 set up like you. Have you tested your brakes out yet?

    the offset is 4mm as per the last picture, and the radius from the 2nd pic is close enough to 109..

    the first picture where you got 30 though.. not sure on that.. from the back of the plate to the back of the mount is around 16mm, and the mount is 13mm thick, so 30mm would be close enough as total depth of the whole part.

    sorry i can't be more exact, but i only have a digital caliper and the batt is almost dead

    it sounds pretty close to what you have though.. if you want them you can have them for $130 + postage (they cost me $220 trade from nissan)

    if anyone wants the Z32 aluminimum calipers + seal kits, they can have them for $150 too

    i may also have the red R31 calipers (i know the disks sold) somewhere if someone wants them too.. they look pretty

    i also have a brand new nabco 15/16" Master cylinder, it is for LHD though, so the hard lines would need to be modified to fit.

    I've just finished building some Z32 brakes for mine. The only concern I have is the thickness of the rotors. It carries a fair bit of unnecessary weight.

    the struts are currently away having some Proflex goodness built into them,() but when I get them back I'll assemble and post some pics. very easy conversion.

    while I was in the process I also made a set of bolt-ons for 180B struts. VT commode calipers and Saab 9000 rotors. I sold them on ebay for $100, which is about what they cost to put together. anyone who wants good brakes for no money, should consider doing it this way.

    Matt,

    which Z32 calipers did you use (there are 3 types from memory, some cast steel, and others alloy from memory)

    they're alloy. other than that I can't tell you much about them.

    I just remembered - I have a question:

    has anyone tried these calipers on a 15/16" master cylinder? will I need to go up to 1"?

    i have been told that a 15/16" is fine for my R34 GTT calipers, but i am going 1" anyway (with a 10" booster).. though i have no idea yet how it performs.

    when you say 10" booster, how big is the standard one? i remember when I got my master cylinder off a 280Z, I had to take the booster off and use my original one because the clutch master cylinder was in the way. have you got around that?

    i think the standard may even be an 8" (it looks a lot smaller than mine!).. Stewart Wilkins used the R30 mounting bracket as well (some modifications were made to the firewall to mount it, with a brace buillt behind it).. but it just clears the standard clutch cylinder (not sure if i am going to upgrade that as well)

    ah. yes that makes sense. thanks for the pic. I think I might end up pursuing something like that on mine.

    Hilux is a Front Conversion not a Rear,

    Im going with R31 Rear, cheap and easy to do.

    Commodore fronts as well just because its like $12 for a disk!
