    Brake advice.

    Hey guys. My current setup is K Sport 8 pot callipers and 330mm discs up front, and standard rear brakes at the back but with EBC pads and discs etc. I still have the ABS but I am planning on removing it.

    I am thinking of going Z32 rear callipers. Heard they are a good upgrade, but will I need the BM57 master cylinder aswell? Only ask as my front brakes are so powerful I rarely use the rears. But I presume the new master cylinder will help.

    Cheers.

    Yes, definitely worth doing.

    Changing the BMC only changes the distribution of brake force from front and rear. I think the bm57 send more to the rear cause on the z32 the rears are 2 pot compared to the standard 1 pot on the s14. I've up graded my rears to z32 without changing the BMC and it works well but it could be better again with the bm57

    Very worthy upgrade and cost effective. Could also consider another K Sport kit.

    It also has a larger piston diameter (1 1/16" vs 1") so moves more fluid and makes for a nicer pedal feel when you've got 6/8 pots up front and 2 pots at the rear. Or there's always the Auto Select 1 1/8" version

    I'm running a Tarox 330mm kit up front and Z32 rears without abs on the standard BMC. Balance is fine and stops really well on road and track....

    I'm sure with a BM57 it would be improved, but not essential

    It will be.

    I had AP Racing 356mm 6 pots with R33 GTR Brembos on the rear and kept the standard master cylinder for years. Change to BM57 was night and day better.

    Really? I may have to find one myself in that case...

    Someone had a link not long ago for the BMC 57 at a pretty decent price.

    Can't remember who/where tho ?

    I think I'll change mine aswell from the reviews above. Is there any other BMC that work. I'm sure The bm57's are getting pretty rare. Can the BMC from a 350z be fitted?

    I'm surprised that so many people haven't changed to the BM57, my brakes were shocking before I did mine.

    got mine from a Z body specialist, might be worth a try, guys name is Mark, 07794015646 or email is sales@automodz.co.uk

    Iíve got k sport 8ís up front and Z32 rear, no ABS, full braided lines. Iíve thought about changing to BM57 a few times but Iíve just never felt the need.

    Not sure if itís personal preference or some stock systems working better than others but Iíve just never had an issue. Loads of power and modulation.

    I bought 2 bm57s from them when I was on holiday in aus and both are fitted and work great. Was about £80 each. Brand new why buy a 20 year old one and you also have the choice to swap it to non abs by removing a grub screw.

    350z BMC is a different design, you would need to modify the pedal/BMC brackets. I think the bolts and nuts are the oposite way around, the piston connection is also different.(can't remember but I will post pictures of the two side by side.
    I was planning on using 350z pedal though so this might have been an issue also, ended up just getting a manual cars pedal and oem BMC.
