2001 4.6L vogue.
I've searched for abs type issues, but only found "clicking" pedal and lots of pedal movement, so:-
Started as "abs type" intervention when turning / parking, with made me think it was a sensor / reluctor, but has developed into banging through the pedal.
Now happens when travelling straight as well.
I sometimes get a heavy banging through the pedal( both feel and audible). This is not the gentle pulsing of ABS.
Occasionally the pedal is hard with little braking, until I push through this.
Often there is a loud "boing" spring noise !
I get a variety of ABS and Traction Control lamps lit, but not in any particular pattern. The startup selftest bit is normal. Sometimes they go out after a short time, sometimes they stay on.
The brakes are physically in good condition with good discs and pads, and free guide pins and calipers.
They don't feel spongy at all.
Vehicle stops in a straight line with the correct braking power on the occasions it doesn't "bang" or "boing".
Oh, and no faults on an OBD tester. Maybe they would only show up on a dealer diagnostic?
I haven't replaced anything yet.
Thoughts?
