Noise

[Bigjeeze]

I am being driven slowly nuts by a noise coming from the discs/brake callipers. Basically as I drive along I get a whistling mild scraping type noise which dissapears if I dab the brakes but comes back again after a few minutes. I have replaced the discs & pads about 10K miles ago, I have looked at the Callipers and pads - everything seems fine - the tyres are fine the rims look OK and all in all I can't see anything obviously wrong.

 

The only thing I can think of is that maybe the callipers need a bit of copper slip or something on them as they may not be releasing properly or something. Other than that is it possible this is a wheel bearing at all? They don't move when you rock them, there is no free play - I don't know what it is!!

 

Can anyone help? :angry:

More than likely its just that the pads need regreasing to be honest, remove the pads on both sides clean them up with a wire brush and make sure the section on the calipers where the pads rest is clean and free of deposits, scrape it with a screwdriver before rubbing down with a wire brush, then give the back of the pads a good coating of copperslip and also on the edge of the pads where it again rests on the caliper, re-assemble and all should be noise free. If theres no movement in the wheel then chances are its not a wheel bearing, if there was movement you would more than likely hear a deep rumbling aswell to be honest........hope ive helped a little :angry:

I'll give it a try - but not until after Christmas - I am going on holiday on Thursday and not coming back until January 5th - I'll do it then.

 

Thanks for the advice - it's gratefuly received!! :huh:

Mine just squeal under light braking. I must admit that it irritates me mildly, but not enough to get out and take the wheels off in this cold weather (and anyway, the wife drives it mostly - it's her car...).

 

When we bought it in August, the dealer fitted new front discs and pads, and I assumed that the squeal would disappear when they bedded in. :huh:

Guys, check that the disc guard has not been distorted slightly. This often happens when discs and pads are changed, the mechanic probably forgot to straighten it.
