Front Pads

[wildbore]

Does Miss Daisy sit on the back seat

No, she sits in the front passenger seat and complains constantly of "feeling sick" whenever we go round a bend.

Seriously, almost all my mileage is motorways. Plus I live in Surrey so, if there is a twisty road, there are a hundred cars in front of me and a hundred more behind. Just occasionally, I get to stretch its legs, but it's a rare moment...

My front discs are scored too exactly like yours Iain. Could it be an Audi fault? Thats three of us in this thread

Good question - though I think proving it could be tricky that its down to Audi - I was surprised tbh that I needed new discs as I don't drive it hard. If we all drive them hard, we would end up banned or dead!

Not being technical, how would scoring occur??? something between pad and disc? Apologies for sounding like a muppets!

Yes, or most commonly caused by not replacing the pads in time and the metal part of the pads damaging the disc. Could be an issue with the OEM pads not giving enough warning or an issue with the construction of the pads.
How many miles did you all do between the warning light coming on and changing pads? And were the pads down to the metal when changed?
I seem to recall someone else on this forum having the same issue too.

Back from the dealers - turned out discs scored, so set of discs needed too.

Front pads and discs. Rear pads 8mm left at 23k miles.

All fitted (incl rear wiper blade) £1265

EEK! I managed to get a complete set of 4 discs, pads and sensors from dealer for less than that (£1195 as package) - not fitted obviously.

Or is "scored disc" the Audi equivalent of the Porsche "inner corroded face" that requires new discs every time my wife has her 997 serviced. First time they told her that was 2000 miles and 4 months after another Porsche dealer had changed them!
We now use an indie.

The scoring in my case was something got lodged in the caliper. Probably a stone.

Of the pad sets that I have seen wear down to the indicator, none have ever been even vaguely close to being fully worn out - the indicator trips comfortably before the pad is worn. It makes sense, really. Manufacturers would not fit a pad-with-indicator if there was even a tiny risk that the pad could actually wear to the point of damaging the disk before the wear indicator tripped as they would then become culpable for the cost of the new disks, their warning mechanism having failed to do its job.

However, in my earlier years, driving cars without pad indicators, I managed to see off a few disks by trying to eek out the pads just another few miles. Luckily, those cars' disks were of the "£50 the pair, mate" type from Euro Car Parts, rather than the "wave disks - you may need to sit down before I tell you the cost, sir" type.

I am also having problems with my brakes.
Whenever I apply the brakes past approx 40% pressure I get a grating noise like metal to metal. I don't drive the car fast or crazy and i never track it I am on 5k miles now. Surely this is way too soon for brake pads to have worn out?

This grating sound: do you hear it at high speeds or just in the last few moments before the car comes to a rest? I have had a grating sound for a while but only in the last moments of braking. Also, despite the grating sound, the brakes are still strong and even.

You can see the outer pad through the wheel spokes to check whether it has worn.

5K on a moderately driven car won't require new pads.

I have the exact same scoring on mine as Iain. I dont think its a stone. I think its something to do with the brake pads. My low brake light came on earlier this week but the scoring as been on the discs for atleast 2k miles

Hi wildbore.

It happens mostly coming to the last moments of braking but has happened on a few occasions before that stage too. I have looked at the pads and there does seem to be quite a bit of pad left.

[alexrs6plus]

Forgot to say that car brake performance does not seen as strong as before, but could just be me not wanting to press so hard on the brakes to stop that noise.

[wildbore]

Hmm. Puzzled by this.

So, I have had the brake grinding sound for a while. Seems to come from the front left and happens as I ease off / feather the brake once I have lost sufficient speed. The noise isn't great, but not so bad as to cause alarm. Last weekend, it suddenly became horrendous. I took the car to the dealer and the RS Tech went out for a drive. Of course, Sod's Law, the car was not doing the horrendous grinding, but it was doing the "background" grinding that it has been doing for a while. He inspected the pads and disks. The pads all have plenty of life left, but the front nearside disk does have a freshly cut score mark on it. All the other disks are fine.

The Tech said the scoring was probably a stone, now dislodged (a reasonable deduction), but that the grinding he could hear wasn't a cause for concern. He said it was akin to the sound that replacement pads make when they haven't been bedded in properly (although mine are the original pads, which are bedded in at the factory). I drive so gently that I wondered if that is the problem...

But now it appears that the grinding sound and the disk scoring are not uncommon! Bizarre.

[norman1979]

Mine have been squeeking for a while to be fair but at low speeds.

I will get some pics up of my scoring but I definitely think there are more people with this issue. What are the chances of us having scoring in exactly the same place

[MikeFish]

Good point. Do you all have photos of the scoring and know on what side it occurred ie left or right discs and left or right side of disc. I assume it is only front discs?
