Hi All,

This is a fairly basic question so hope I'm posting in the correct forum -

2005 Audi A4 1.8TQM - my brake pads (front and rear, I believe) appear to have the wire coming out of them that gets attached to some sensor. My question is, when the pads wear down sufficiently, will I get some idiot light/dash warning message? Or are these wires simply to tell the ABS computer how it should apply brake pressure based on remaining pad thickness? Do the pads also "squeal" when they are worn down to the point of needing replacement?

 

Your breaks can squeal at anytime, as for your other questions I cant answer them as Iam new.

 

it will tell u when they are running low.

 

I could be wrong, but I was told my A6 and my 2003 A4 3.0 MT6 only have brake wear sensors on the front pads. Nothing on the rears. Squealing could be dirt, rust, or (worse) your pads are down to the rivets and ripping into the rotors. My Crossfires (SLK320 running gear) are also front sensors only.
