91 ABS s13

aight so i swap on r33 calipers, with conversion lines..

i gravity bled them the first time.. and they felt ok... but not 100% perfect. i then bled them normaly.. and the pedal dies.. dead... no pressure
then i relized their was air bubbles coming from the MC, as if u put a straw in it, and then blew bubbles, every time the pedal was pressed. (bubbles never end)

i cant bled the system out, i dont know what the problem is.. i tryed bleeding them out for an hour.. nothing, the MC makes FOAM! mad Air!.. i have never seen anything like it..

any ideas?

this is going to get messy if you do it with the M/C in the car.

Open all 4 lines on the brakes. Slowly stroke the MC/Pedal unitl you get flush fluid. You are going to go through alot of fluid.

Or, pull the MC and bleed it on the bench.

Also you should know that to properly bleed an ABS equipped car the actuator unit must be unplugged. As long as it's powered it will try and fight the pedal engagement.

thanx for the replies

ok so im going to bench bleed a new MC i got.. but that still doesn't explain where the air is coming from.. it never ends.. every time i press teh pedal down air bubbles shoot out... wtf..?

i checked my new lines with my r33 calipers.. nothing seems to be dripping.. or wet...
