I have recently had a ABS (Antilock Braking System)/Brake fault show up on the MGZT 190.

The fault consists of juddering/pulsing of the brake pedal, this only happens when i am coming to an halt either at a junction at a round about or when i am parking up, at only very slow speed 3-5mph, if i brake at speed ie 20-60 no pulsing or judder until the car is coming to stop as i say above.

I have no ABS light on the dash the ABS light passes the initial test, lights and then go's off after a few seconds.

I built an ABS test gauge with an old ABS sensor using the loom part and the ABS to hub which is connected to a multimeter as this one below.

I had similar issue,
after a while it progressed to the ABS warning lamp coming on and loss of speedo, then fault clearing itself
a little bit longer and it ended up as a permanent fault, with an erratic fuel tank level indicator as well.
The ABS cable to the front drivers side was replaced and all well, including the fuel tank level.

Planning is an unnatural process, much better to just get on with things, that way failure comes as a complete surprise instead of being preceeded by a period of worry and doubt

Hi Mike.
Yes I finally got it sorted out today I am at present uploading the photo's to my album but photo bucket is playing up so taking some time to sort out, once I have sussed why photo bucket is allowing all my albums to be shown if anyone clicks on my photo I can post up my findings and how to remove and replace the faulty item, which
turned out to be the wheel bearing O/S rear.
