    OK, help needed.

    recently converted F series drums to r31 skyline discs.
    new parts include:
    new pads
    new rotors
    all braided lines
    new recoed calipers.


    problem being, as soon as i bleed the system thge rear brakes still have pressure in the lines. so the rear calipers are sort of locked on. the car is still drivable but cannot push it.

    originally i thaught it was the brake proportionaling (spelling???) valve attached the the right hand strut tower so have biapassed that with a joiner. and same problem.

    car is running hydrolic handbrake only (no cables connected)

    and RB20 master.


    when i had the drums it was fine. all i have changed since is the discs and braided lines.



    need help urgent got to leave for QLD thursday!! :confused:

    It's your brakes.

    They're doing it wrong.
    You can have any brew you want... as long as it's a Datsun / Corolla / What is that?

    yes and it does not go back to the master.

    turns out to be the calipers.

    R31 calipers do not like hydrolic handbrakes. because of the manual handbrake mechanism
    built in to the piston.

    purchised some VS commodore calipers today. same bolt pattern and no handbrake as the
    handbrake is like a drum style on on these cars. just about to install them.
