Brake warning light
This might seem like a daft question but what actually causes the brake warning light to come on, mine's on but I can't see any reason
why?

Low fluid in the reservoir (or broken switch in the lid), or whatever is being used to switch the bulb test function - usually a switch on the dash or
the handbrake. Other than that a short in the wiring.

You need to understand how it is wired first.
The correct way is to have an ignition controlled positive to your warning lamp and then from the lamp a wire that loops to your resevoir switch and
either a test switch or the most common, hand brake switch.
Both the handbrake/test switch and the resevoir are open circuit and put the lead from the lamp to the earth/negative.
The handbrake will put the circuit to earth while it is even slightly up from the off position and your resevoir will put the circuit to earth if
the fluid drops.
You need to check that both are working correctly individually. Best way is an ohmeter so that you can test to see if you have open or closed
switches and work from there.
