    Hi guys!

    my 200sx is using a r33 gtst 4pot front and 2pot rear.

    now my question is i have already change my master pump on rebuild kit and braided line but my braking is not functioning well. seems like there is more air inside the brake pump. we've try to bleed few time. but the result is still the same.

    can anyone guide me?

    What did you change the master cylinder for?

    Do you still have ABS?

    I had a problem bleeding up a master cylinder which had been sat empty for a while, I can't remember exactly what the fault was but the brakes just wouldnt bleed up until I removed the master cylinder and reassembled the master cylinder piston, which didn't take long. I bled the master cylinder on the bench and then bled up all the brakes absolutely fine. Mine is a standard PS13 master cylinder with R33 GTST brakes all round.

    If i remember rightly an o-ring on the master cylinder piston had slipped or needed replacing - it wasn't producing the correct pressure so the the brake pedal always felt spongey..

    Hi r3k1355

    i bought the r33 gtst brake kit from halfcut and they even give me the R33 gtst master cylinder. thats is why i have change it from my previous oem 200sx master cylinder. and talking about ABS, while i install my new adaptronic e420d ECU, the tuner had it remove. does it make any change is i remove my ABS?
