ABS cutting in

[Griffter]

Hi,

my ABS seems to cut in under gentle or firm braking - but get this - ONLY when turning left (however gently)!
The classic scenario is pulling up at a roundabout, or a T-junction to turn left. The pedal will 'pump' what feels like once a wheel revolution or so - not a constant grumble which you might get under total lock up. Braking in a straight line - even hard - the pedal is firm and feels normal.

Any ideas what could be causing this? I can't work out how to remove the sensors to clean them...

Cheers.

more likely a loose caliper and or a warped disc TBH

Cheers, but it's definitely the ABS. With the ABS unit disconnected it doesn't happen. Top suspect at the moment is a cracked reluctor ring. I've had this before with similar symptoms (different car) - although it did it all the time coming to the end of a stop, not just turning left.
