I’ve got 1994 Z28 and I went to bleed my rear brakes when I saw that I had no fluid going to the back. I got out a diagnostic scanner and got the code C0057(left front ABS motor shorted to ground) I tried bleeding the abs pump but that didn’t help. If anyone’s got any information on how to resolve this it’d be greatly appreciated, thanks.

Sounds like you may have to fix the cause of the code before you can get the system functional. Try the ABS section in the 1994 factory service manual. Free download courtesy of GaryDoug:

You can find the code description in there.
