SBC Screw up Help!!!!!!
Thought I didn't need to disconnect the SBC computer when changing brake hoses
Well now the brakes won't work. Shut off the car disconnected the SBC reconnected in the usual way and still won't work.
Have now disconnected both batteries hoping it will reset. How long should I wait and will work?
Tried the wheel trick, but it wouldn't work with just the left side off the ground.

Will not apply? Do you get the warning in dash?
How did you bleed the lines after replacement?
so if I read this right, you left all power hooked up, removed the brake hoses, reinstalled and started the car?

Now you’ll have to bleed as much as possible. Hook it up to an MB SDS. Allow the pump to purge. Bleed it manually. SDS pump purge, bleed it purge, x7-10.
Best way to avoid air and cut down pump cavation is a master brake pressurization setup for bleeding. Pressure forces fluid and air more effectively throughout the entire system.
Good luck
