    Converted to Manual Brakes-spongy pedal

    Hey guys,

    So I have a 1994 M- Edition shell with ABS brakes. All the lines were deleted, module, except the brake booster.

    I changed the brake lines all to stainless steel brakes, NB1 Calipers (front & rear) & Brackets, 1.8 slotted rotors/pads (for a 94), Manual 1.6 brake master cylinder.

    I bled the system by doing the "pump and crack bleeder valve" method. I bled the system by starting with the LEFT REAR, then RIGHT REAR, RIGHT FRONT, then LEFT FRONT. After bleeding it for awhile (making sure there are new fluid coming out and clean streams) the pedal still feels a bit spongy.. Should I keep bleeding the system or do I need to change a component?..

    Couple things that may be the problem:
    -Worn/internally/weak leaking MC (but was working fine from the 92)
    -wrong booster?
    -possible leak? (I dont see any..)
    -too much air in the system


    I did not bench bleed the master cylinder... so air is a factor...
