Fairly new to this lark but I have a question.
Just fitted a new brake master cylinder, done a manual brake bleed and a Tech2 driven ABS bleed, since then the handbrake/low fluid light stays on, have checked the handbrake switch and the low fluid switch, both appear ok.
Any ideas or pointers would be welcome.

You need to check the error code with a Tech2 or similar,
It will indicate to which is causing the fault/error.
When repaired, reset it with a Tech2 or similar.

Will likely be something to do with the brake switch in the master cylinder (where the piece of loom runs to on the side). Something could be pushing the switch shut, or the loom is shorting out somewhere, or the switch is broken. Or your rotors are really low and your old switch was broken. Does it stay on all the time or does it only do it when you hit the brakes? Basically supposed to just be a switch that lights a bulb up on the dash when the piston inside the master cylinder travels certain distance.

Maybe a airlock behind the sensor when u replaced the system, undo the sensor and see if fluid is present.
