Vectra brakes ABS compatibility - bev1966

Hello, does anyone know about Vectra brakes. I've got a problem with my P reg SRi failing the MOT due to excessive travel of the brake pedal. I've had a second-hand master cylinder fitted but the problem still remains. The mechanic has suggested that the replaced master cylinder is faulty but I have since spent some time on this site and others and it seems more likely that my problem lies with the ABS unit. I have the chance to buy a ABS unit from a Vectra 2.0i di turbo diesel and just wondered if anyone knows if this would fit my 2lt 16v SRi, also do I need to buy ABS sensors as well (like I know what that means!)? Please help before this car finally sends me over the edge.

Youre sinking brake pedal is very likely to be an abs unit fault.The only difference between models is whether the car has traction control fitted.The abs sensors are all the same.

Vectra brakes ABS compatibility - none

I recently came across a Vectra with a sinking brake pedal. As the car was under warranty it was returned to the main dealer. Initially they decided that the ABS unit was faulty, this meant a 3 day wait for a new unit. Although no reasons were given, they then decided to replace the master cylinder, another 2 day wait.
Many years ago I made a set of master cylinder blanking plugs, just unscrew the pipes, replace with plugs, bleed the cylinder and check for the pedal sinking. With a good cylinder the pedal is rock hard with very little free play.
