I've had brake drone on the SC for a while. It was there before I replaced all the discs and pads with TRW ones from Advanced Factors, our forum sponsors.

The drone comes under heavy prolonged braking from high speed (normally) and although I can't be certain, it 'feels' like its the OSF wheel, if not maybe both fronts.

The discs are not blued from overheating, and there's no appreciable extra heat coming from the wheels as you'd get with a sticking calliper.

I am no brake expert but I am wondering if I have a calliper where the pistons are not pushing equally. The only way I can type what I think the noise would sound like is as follows, and it's in direct relation to speed too

"wub-wub-wub-wub-wub-wub" etc etc

Normal braking is fine, no vibrations, no wheel wobble, just this horrendous noise.

Any ideas on how to diagnose? Discovery 4 HSE

Aren't Brembo the OE on your SC then Stan?

Wish I had paid attention to what came off the car when discs and pads were done.

I guess replacing pads is the cheaper option of replacing callipers...  Discovery 4 HSE

I have OE pads in mine and I get a "drone" type of sound under heavy braking. I'm just think its the sound of three ton pulling up! I've learned to live with it. You can spend a lot of time and money chasing that type of thing around.

Well, I've never had it before in my other L322's, and as all but the callipers have been replaced, that's where my suspicion lies Discovery 4 HSE

Must admit I haven't heard it before in my 4.4 or my Sport, but I think its just a characteristic of the momentum and all the braking components - that's if its the same noise that I get.

It's VERY loud. You can't miss it. It reverberates the car whilst it is happening, if I release the brake and reapply with different pressure and force, I can make it go away. Discovery 4 HSE

I get the same in my SC and agree it seems to be OSF. It's going into the main dealer next week and I've asked them to look at it. Will let you know the result. "On first name terms with my local Dealer......now."

I've said it before many times on here! The only pads to fit to Brembo equips cars are main dealer pads ONLY!!! Brembo do NOT make brake pads! So if you buy Brembo branded pads they are either a pad made by a company trying to cash in on Brembo's good name or fakes once again using Brembo's name/logo's to trick unsuspecting customers... Simple!

Buy cheap, pay twice!!!

So Craig..your saying that the Brembo pads I purchased from Advanced Factors are not made by Brembo at all?

Yes sir... 100% NOT made by Brembo sir... As I stated above, Brembo do NOT produce brake pads! Any brake pads in a branded Brembo box are NOT produced by them and probably are inferior pads being sold in that packaging to hide there originality!
Meaning if you buy Pagid, you know they should cost cheaper than OE money!
