Just running through some of the possibilities and would appreciate any ideas lads?

Car been off the road for 6 or more months. Brakes were disconnected and blanked off with hardly any fluid loss... all bled and feel good. ABS light goes off as it should, its just the handbrake warning / fluid warning one that is staying on.

What I've tried so far includes:

Fluid level is good and have changed the level sensor / reservoir cap switch with my saff one (which works on that car)

Pulled off the abs pump connection and reconnected a few times (but need to check to hear if this running once I've left it awhile).

Pulled the handbrake on and off a lot in case the switch is sticking - think this is under the centre tunnel plastics if I need to get to it???

If I am overlooking something obvious lads - would appreciate a nudge please - dreaded MOT on Monday ;(
