Pedal difference between 17/16th and 1" BMC - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

boosted23 · 05-09-2016, 09:21 PM

I recently just did the z32 brake conversion. 30mm aluminum all the way around, 17/16th BMC and 92 Z32 ABS booster.

I did the fronts first and left rears stock. The pedal was touchy as hell!!! So I did the rears now. The pedal got better but it still is a little too touchy for me. Now......my question is would the pedal feel be enough for me to notice if I switched too the 1"? I want a better pedal feel but if the 1"isnt that much noticeable then I need to look at other options. Thank you.

Having tried all 3, I landed on 15/16 as my favorite for pedal feel. Full z brakes, front and rear with s13 single diaphragm booster.

The single diaphragm is the MT one? I chucked mine.....does your pedal have a high engagement? Almost as soon as I touch my pedal they are grabbing and I don't have much movement at all before they are grabbing hard

Swap that booster back

I used a 17/16 and switched back to 1" . I like the way it is now, the 17/16 was too big.
