i just did a full front and rear caliper swap on my 95 240sx with abs. installed the calipers, used stock 300zx lines and a 300zx bmc.
when i go to bleed the calipers from driver rear, pass rear, pass front, driver front i get a solid pedal feel. but once i hit the street and make my first stop my pedal goes real soft all the way to the ground. almost like i have no brakes.

please help. i tried bleeding with negative cable off. i hear something bout bleeding abs module but havnt tried that yet. kinda scared to touch that lol. thanks

*UPDATE*
so after 3 bottles of brake fluid and hours of head scratching thinking WTF!!

is wrong with this swap, i found the problem. i had thee master cylinders that were all messed up. one was stuck, one was leaking fluid, and the other was leaking thru one of the brake line screws. so i fixed the threads on the master with the screw leak and connected it back up and pressure bleed it. damn the breaks breaks feel amazing!!!! thanks for everyones help

. i picked at the car when ever i had time, sorry for the late update but its finally over.
