Brake Bleed Procedure
Hey, guys. I have a '96 Z28. I have replaced all the calipers. I have bled them. When the car is off, I have pressure on the brake pedal; however, when it is turned on, I don't have any pressure. Furthermore, the "brake" light is on. I've read that there is a sequence to bleeding the calipers or the ABS, but I don't want to start over. Do I? Or is there a shortcut? Because the lines are bled, but there is air in the ABS.

Re: Brake Bleed Procedure
Did you have any codes for the ABS system before you tried to bleed the brakes? If so, you need to "home" the ABS motors. Needs a Tech-2 tool, or an alternative procedure outlined in the factory manual. Detailed procedure for sequence of bleeding in the manual as well.
You can do a free download of the 1996 factory service manual:

Re: Brake Bleed Procedure
No ABS codes? At a minimum, you should have DTC 86 = "EBCM turned "on" the the red "BRAKE" warning lamp" - or DTC 87 for a short or open "BRAKE light circuit.
If you are sure, then just follow the procedure in the factory manual for bleeding.
