As you said, for a 2006 DTC B0101 is "Discard Front End Sensor 1" related to the SIR system and the SDM (Sensing and Diagnostic Module for inflatable restraint system). On a 2006, the inflatable restraint "front end sensors" are somewhere behind the front bumper system, and tell the SDM the severity of a front end collision. I have no idea what the code means for a 2004, if anything...others here have had code scanners come up with strange codes of doubtful validity for their model year.
The cause of the code is likely something that was disturbed or disconnected during the service. I would go to the areas where work was done and look for wires that may have been disturbed or disconnected during the work activity. For example, check for disturbed wires or harnesses (from "front end sensors") around the front wheels that may have disturbed during brake bleeding.
Check each wire connector in the vicinty of the work to insure it has good make-up...it's possible a wire appears connected but is just hanging together. Take each connector apart and put it back together if necessary to insure you have a good connection and latch up. Also, keep a eye out for any evidence that individual conductors have been strained, possibly to the point of almost pulling the wire out of the connector.
On a 2006, DTC B0101 is set because the SDM is getting an incorrect signal or no signal...I don't know what your code scanner thinks it's seeing, but I'll bet the problem is a disconnected wire; i.e. no signal.
