a low voltage spike on first start of the day is known to produce the RED brake warning and beeps..
What colour brake warning do you get, AMBER or RED

its red and yes it bleeps but it also happens when you can be driving along

Move the brake fluid reservoir level lead away from the battery lead and put a bit of foam pipe insulation round it.
