right the abs light has always been on since i got the car.

so yesterday i changed all the wheel sensors but the light was still on

then this morning i was zip tying some cables up out of the way and

noticed that the green relay under glove box was not plugged in properly

plugged it in and the light went out

then just went out for a drive and at first the brakes work fine then the

pedal drops then pulses/vibrates 3/4 times and then the car stops slowly.

then the brakes dont work for a few seconds after this has happened and

the pedal is rock hard wont stop at all .

anyone know what this could be

 

This is probably why someone un-plugged it in the 1st place!
Could be the wiring has deteriorated as it often does causing intemitant faults or it could be the ABS ecu itself.
If you want another abs ecu give me a shout i have a few kicking around.
