I had my front discs and pads changed (under warranty) approx 5000 miles ago due to vibration under braking.
Guess what, it returned around 1500 miles ago just as bad as before, looks like it's another trip to the dealer then.

I had this problem of steering wheel shake since the D4 got to circa 80k miles. Had two new sets of front pads over about 8 months, both sets improved shaking somewhat but not completely and the situation returns over time.

I changed rear discs and pads to eliminate these as an issue/ were getting old anyway.

Speaking again to my Indie he offered to change front discs again. I decided that we would also change pads and calipers as well.

THE PROBLEM HAS GONE AWAY (500miles so far). Also the braking has improved dramatically, I had not really noticed the braking has deteriorated so much.

So in my case Calipers would appear to be the issue even though they were showing non of the usual signs of being faulty. The fact that the braking has improved seems to add weight to Calipers being the issue.

That's good feedback. I know some people are plagued by this issue.

I can add to this that I have also had problems with shaking steering wheel when braking. When changing discs and pads it went away just to come back after not so long time/kms. The current set of discs is Brembo with Brembo pads as they are supposed to be high quality. The same problem reoccured at the same rate as earlier... I can´t believe that modern, high quality discs should easily warp so I checked for other possible sources. When checking the pads I could see that they had shiny spots on them so I resurfaced them using an ordinary sander to take away just the top layer. Results? No vibrations since and this was maybe 5000 kms ago. I assume the shiny bits of the pad surface gave an uneven brake force creating vibrations but I don´t have a scientific explanation. I just know that the discs are not warped and sanding the surface of the pads helped 100%.

I wonder if unbalanced ABS is being momentarily activated by sudden bite from the disc pads, giving the effect of warped discs. The idea fits with new pads curing the problem for a while, and pad sanding achieves the same.

In my case, the discs were actually warping, with the resulting ‘judder’ through the steering wheel.

Brembo dont make brake discs they do make brake pads, iv recently found this out. They may be badged as such but are usually cheap chinese crap rebranded and sold via ECP via a legal loop hole.

I confirmed this with my local ECP store and they said it's legal and some are better than others but they get a lot of warrenty returns.

I will be doing the front discs and pads on our D3 shortly I wont be using ecp

I have a company 2015 D4 and when it had approx 70K on the clock the problem with warped discs started. At that time the car was still under the warranty. We received 2 sets of new discs and pads from LR and the problem always reoccurred after doing approx 5K miles. After it happened for the 3rd time I gave up on LR as they failed to provide any solution and also refused to exchange discs and pads again. I fitted a set of Britpart drilled and grooved discs and EBC pads bought from PowerfulUK. After doing max 10K miles the problem is back yet again. At least I know the problem is not the original discs and pads.

Having read previous comments I will try changing calipers next time as well. I am just wondering...would changing just the brake pistons inside the calipers do? I believe calipers on their own could be fine and it is just pistons that are wrong. What do you think?
