Any codes?

Check for vacuum leaks, I think the minimum is 8" at the vacuum switch on the left inner fender. You should have 25" from the vac pump to the booster. Having low vacuum at that vac switch will cause the abs and red brake lights to come on with no codes.

Any sensor that grounds out will set a light: fluid level switch if equipped, combi valve switch under master cylinder, parking brake switch, or RWAL diff sensor shorted to ground.
