Hello, I've done a bit of a search but couldnt really find anything that answers my question definatly...

I have an R34GTT and i'm in need of a new brake master cylinder.

What cars/models share the same cylinder as the r34?

could I purchase one off an r33 gtst for example and it work fine? as long as its an ABS model i should be right, correct?

Just dont want it affecting brake bias in a bad way or anything like that. All of my brakes are standard so not really wanting to upgrade just want a replacement.

Cheers

I've just realised I've got a BM50 BCS after ducking out to check.

I thought r34 GTT's came standard with BM44's?

Could this be partly to blame for my soft pedal feel because i have a larger bore size? or am i not even close?

I doubt that would be the cause of your soft pedal. I went to a larger master cylinder, and it made the pedal firmer (not softer).

If there are no leaks, the obvious thing would be to bleed or change the fluid and see if that fixes your problem.

    • Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure
    • Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.
    • Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15  
    • Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.
    • 8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
