Brake Master Cylinder Leaking...

Its been happening for quite a while now, was fine when driving the car... just topped it up and all was well. Can see it peeling the paint off the booster.

Since defect it sat for 3 weeks, (completely forgot about it) which gave it long enough time to completely empty itself. Now with air in the system, brakes are useless.. So cant drive it to get repaired...

So my question is, should I just take it off & get the seals redone? Or is there more to it then that. Or just buy a completely different unit? Anyone here that can vouch for a place to do it? Was going to just bleed the brakes and put new stuff through it, but seeing as its gonna do it again anyway.. might as well do it once, and do it properly. :)

I would take it off myself, never really looked at the thing so just wondering if its an easy task...

Thanks.. much appreciated. :)

Adam..

both, i could be wrong and R34's for some reason are stupidly expensive, but to give u an idea i paid under $100 for mine in the 32.

i deal with all clutch and brake down here in SA, maybe try them and see if they can send u something.

i just rang nissan here in brisbane they want $460 for a R32 new brake master cylinder and around $190 for a rebuild kit

i'm a bit weary of the rebuild kit though, i really can't be f**ked pulling it apart once to see if it has scoring along the barrel then trying to put it back together so i can drive my car in the 10 days i need to wait for either one depending on the condition of the barrel to come from Japan

Still have the baggie, it was sitting in my rubbish for when I clear away that area..

protex 210J0159 is what is on the label.. Make sure it is the 1" master, and I can't remember if it was the nabuko or tokiko, think it was nabuko..

Remove the master cylinder, pull it apart, follow the workshop manual, easy as.. make sure everything is sparkling clean, you don't want any little bit of dirt getting in there. after you remove the piston assembly you can shine a torch in there and you will be able to see if there has been any corrosion, contamination, scoring, etc. In my case it was just old seals that lost tension.

Brakes are better than they have ever been. Transfer case clutchpack decided to die shortly after as well, never ends.

      Leak from Tokico BM50 Brake Master Cylinder

      By GTSBoy · Posted

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
