Welcome to the Forum!

 

Sounds like its identifying another brake issue. Check the pads are sufficient,

as sometimes when it gets too low some cars can pick this up as an error... also check that there are no seized pads...

hi thanks for the welcome, ive fitted new pads/shoes and checked pistons are working freely, i went to ford dealer and asked but was told it could be in need of new cluster but would need them to configure it when ive fitted second hand one. cheers

could be that there was a sensor present that may have been knocked loose when you were replacing the pads?

 

If you slam the brakes on, does the light stick on or go off?

not necessarily referring to the ABS sensors... I think there is another sensor (if I am not mistaken) to detect when the brake pads get too low... so to warn you before you start braking with metal on a disk, rather than a brake pad?

hi checked again but no other sensors ( no wires going to hub or caliper ) and no wires from engine side, if i take abs bulb out then theres no reason to fail it on that ( mot ) as car is non abs but i dont know about handbrake bulb ? cheers.

dont take the handbrake bulb out, the car is trying to tell you something, and somewhere a sensor is throwing up this error. It might be a corroded wire, or a wet wire.

 

Is it disk brakes all round, or shoes on the back?

hi its disk on front and shoes on back, the only sensor i can think of on non abs car is fluid reservoir, sensor on lid to tell you when fluid low, i tested the plug but no volts present when ign on ( three wires ) :(

could well be thats the culprit I suppose... Can you trace those wires back to check for breakage?

red/black + blue/black + yellow/black cheers

 

the yellow/black is probably your 12v feed from the fuse box, looking at a wiring diagram i have here for a mk2 focus but then the rest is completely different to yours

 

but i would suggest that the blue/black is earth and the red/black goes to the cluster

 

I cant be certain though, but i will check and see what other diagrams i have here..
