What you need to do first is check for ABS malfunction codes .
From the codes you will then know what part of the system is being affected by the rain.
Most likely one of the wheel speed sensors checking for codes will let you which one .
Do a ABS code check then please get back to me with the code.
ok greg let you know tomorrow
the code that came up was v-u0415 anti-lock brake brake system control module, on tester it said right rear abs sensor ,i have notice as well the brake pedal feels soft and creeps could it be air in the system as well , i have not changed the speed sensor ring could it be the ring
it,s a 1.4 16 valve 207XXXXX57 plate , yes the code was re set after new sensor fitted and brakes bled , lights stayed out for a while, the lights came back on , abs light keeps going off and on , do you think it needs a new sensor ring , or the brakes bleeding
no said no codes detected
no , greg
it sounds as though it keep resetting it self
can you tell me where the abs module is on the car please
ps brakes feel soft and a little bit of creep could this give you a falls reading i have fitted a new slave cilinder on that side
