Hiya mate. Yeh it all primes up as it shud. I can hear the abs ecu clicking twice as it normally does too.
The first one my hand brake light goes off. As it always has dun....and second click the yellow light shud go but it doesnt.

Iv also tried taking the battery off and unplugging the abs . Running the car then plugging it back in.
How does the abs unit work? Is it like a solinoid piston breaking the pressure?
