I was unfortunate enough that when I first got my 32 it had the front & rear single-piston calipers.

Then was lucky enough to pick up a 33 GTST for next to nothing so swapped brake calipers (& rotors) over.

They stopped the car fine but even when properly bled the pedal felt like it didnt start actually doing anything until it was about halfway down.

I figured the 33 m/c probably had a bigger bore size & even if it didnt, the 32 m/c was a weird design with fluid going to the end of the bore then doing a u-turn before getting pushed down the line, so figured even if same bore that the design was giving me the low pedal feeling.

So recently when I fitted the motor & gearbox from the 33 into my 32 I also swapped master cylinders, modifying a few lines along the way.

However, now, even with the R33 master cylinder that was originally matched to the calipers I have, I have the same low pedal feel.

I am going to re-bleed the brakes but dont think it is going to make much difference.

Does anyone have any other suggestions or has anyone had this same problem?

Thoughts & advice would be great.

Cheers,

Brett

My R32 used to feel like this too, and after upgrading from single piston to R32 GTS-t rotors and calipers the problem still occured.

Is there any way you are able to 'tighten' just the brake pedal perhaps? Mine just feels loose, it doesn't feel like it's actually in the system.

Sorry I can't help but someone else might have had a similar problem with some advice hopefully :rant:

Dont imagine master brace will help as it is first half of pedal thats soft. When I am pressing that first half there is bugger all resistance so dont think the firewall would be flexing whatsoever at that point.

& yeah, bled master cylinder before calipers but checked for air again after...

    • 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.
