Ford KA, handbrake light keeps coming on

Ford KA, handbrake light keeps coming on i.e. the dashboard light when you put the handbrake on. In the case with a Ford KA, when is the light coming on? First check the brake fluid level in the brake fluid reservoir is correct (Very important).
When is the light coming on? If coming on when the car is stationary then check the handbrake switch, check the connection then the switch as it may just need cleaning with switch cleaner. If the light is coming on then off intermittently when driving and the brake fluid level is correct then suspect the fluid level reservoir cap float switch.
Test fluid level switch and check as shown in this video. Note that if you are in any doubt about your brakes especially if the car state is unknown then please seek help from a qualified mechanic.

My KA, had to have new rear brake hose fitted.
After a few days my handbrake warning light started to flicker
When going around a corner, or going over a bump.?
After Checking the wiring diagram, it appears that the handbrake light
Is wired into that brake switch on top of the reservoir.
I did check the level, and it looked ok. But i double checked
Again with a bright torch, and it did need a top up.
Worth a good check , as that float is very accurate.
They could not have topped up enough during the repair.

Nice informative vid. Maybe a bit better light in the cab so we can see when you're in the car, but otherwise nice no faffing about video
