R30 Brake Mc Problems


Recommended Posts

Hi everyone.

I have an 84 R30 skyline(not tokico Master Cylinder) with disc fronts and drum rears. My brake master cylinder has failed and apparently my only option is to sleeve and rebuild it. I was wondering if there is a simple 'bolt in' upgrade?(from searching the R32 MC seems to fit, but I am not sure if it needs any modification to do so). Seeing as I am going to have to spend a couple of hundred to rebuild the cylinder anyway I figure I may as well upgrade if it doesn't require much more effort.

Cheers

Michael

Are no new Master cylinders available from Nissan or Repco etc?

I'd stick to the std size if possible unless you're upgrading the entire brake system

The later model master cylinders are all designed for Disc / Disc, not Disc / Drum like yours and also designed to feed only 2 lines into the ABS unit.

The bigger later model m/c will increase the pedal pressure if you don't increase the wheel cyl sizes as well & possibly get so hard you might have to be Eric Banner (aka Hulk) to make the car stop.

Chris, yes the new is available ex Nissan at a mere $600.00+

I haven't checked the a/mkt parts industry for some years, but last I did they were getting hard to find & some suppliers listed as obsolete then.

$200.00 for re sleeve seems a bit high for me, have you checked around your local brake specialists instead of mechanics as most mechanics sub them out and put on their margin. Try Better Brakes or a similar brake parts supplier.

Cheers, D

    • Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.
    • They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.
    • Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....
    • Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)
    • Thanks for the replies guys, it's really appreciated.  It seems the kit was supposed to come with those injector bosses but hasn't. Unsure if they'll help as even with the adaptors to make them a 3/4 height injector they still sit too far out so mount the fuel rail?
