Does anyone know that common sound you hear from Holdens and Fords where a "light" scraping sound speeds up and slows down relative to the wheelspeed? Something to do with the brakes? It comes and goes, sometimes there, sometimes not. Especially there after a lot of driving.

Any cause for it? Any reason to be worried?

Sorry mate, never heard the sound on my car or any other friends falcons or commodores ive ever been in.

It's the widget scrapping on the dooveewacka.

Might be low pads on the brakes? not really sure what you are talking about though.

It's like a hissing sound "tsss tsss tsss tsss" heheh.. speeds up and slows down relative to the speed of the wheels. Pretty sure it's not low pads as mine are still good.

I am led to believe it is the handbrake rubbing inside the disc rotor.

I know it well... three main causes;

1. damaged axle flange/collar thingy (correct name escapes me at the moment) - my car has this issue at the moment; this is the cause in most cases
2. handbrake pad scraping
3. warped disk (though unlikely)

Yes it's a very common problem with the Falcon and Commodore and has been for the last 6-7 years (or more). It's the hand brake shoe. A temporary fix is to file off the leading edge of the shoe, but the hiss hiss sound will be back as the shoe wears out. Try this if you can't be bothered taking off the rear discs. When you hear the hissing sound while driving slow at 5-10 km/h, pull the handbrake upto the first click (pads hardly touching), drive on for say 100 meters then put handbrake back down. This will skim the handbrake shoe's ever so lightly and put a bit of heat in 'em and stop the hissing sound untill, if you're unlucky enough, the next time the handbrake is used.

Interesting! It comes and goes. Only happens to me once every few months, and it goes away later in the same day. It does seem like a problem in cars only a decade or so old. Thanks for the information.
