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...
