My Lexus sc300 having problems when I depress on the breaks all my electrical system shuts down and come back on. This problem only accrues when I depress on breaks. Please tell me what is causing this shut down to system.
It could be a bad ground somewhere causing the problem. If problem occurs only on hard braking, something could be loose and the braking is causing wires to sway and loose contact or a bare wire is being intermittently shorted due to the movement.
Not an easy job to find the source so I would suggest checking the battery terminals etc for clean and tight connections for a start.

Ensure wires are not dangling near brake pedal and being affected by the pedal during braking.
