front brake pads worn warning

[nordic venture Junior Member Find all posts View Profile Close nordic venture]

flicking through the owners manual for my 1997 3.0td GX auto i saw a bit about an audible warning when the front brake pads wear low. what sort of noise? coming from where?

any ideas or does this sound too good to be true? oh and i'm not meaning a grating metal on metal sound.

Have you ever heard a car apply their brakes and it makes a high pitched sqeal? Well thats the noise you are refering to. Most manufacturers use this method.
cheers

Not exactly sure with what toyota are talking about (maybe one of there spies could add a little here)
But cars I have had in the past use a little plate behind the pad with a small tab the bends around the side of the pad at a pre determined distance.
When the pad wears down to this point the tab vibrates on the disc causing a loud squeal sound.

Early warning system for worn pads.
Hope that is right.

Spot on Jeff. Designed to make a noise before the pads themselves are on the metal.
