Front discs keep warping on E46 - advice needed
Discussion
Hi guys
I'm now on my third set of pagid discs and pads (fitted by a garage) on my 320d tourer as they keep warping. It's deffo warping that's the culprit as they showed me on the brake tester.
I bought the parts from ECP so yet again took them back. While I was there the pagid rep happened to be around and said that they wouldn't cover the labour cost as no fitting kit was purchased and that could have caused the warped discs !
I then pointed out that a) the kit wasn't offered to me when I bought the parts, and that I really couldn't see how not replacing a fitting kit (which I guess is just pad securing clips ?) could cause warped discs !
The latest set are performing OK so far but I'd really appreciate any advice on if the fitting kit line is (as is suspect) a load of old tosh, or if there is anything else that is causing the warping.
Many Thanks
Nat

Some good suggestions here, all could be part of disc overheating. I recently had poor heat transfer from the disc to alloy wheel (proabably part of refurbishment) causing the excess heat in the disc however this is probably rarer than something like sticky caliper or pad leading to this.
Thanks guys - it's the fronts - reputable garage that fitted them as I don't have time. No recent wheel refurbs - sticking calliper is a good shout - ill jack it up and give the wheels a spin the weekend - hope I get it sorted it's doing my head in and I'm probably more attached to it than my 997 lol

Front suspension wishbone rear bushes.
On a 3 series they look like this,
on your v70, iirc, they're pressed into the front wishbone.
Thanks for that - I will investigate. I've already done all of the discs (fronts twice!) and also 3 out of 4 wheel bearings (they made a BIG difference). But I still feel a vibration at about 75 and - road surface dependent - I get what I would describe as a warped disc sensation. Odd. And annoying.On a 3 series they look like this,

Still reckon sticky caliper though.
I had "warped disks" on my E61, which gradually got worse. Local indy replaced the disks and pads, but when he took it for a spin, they had made it worse. He tried a different brand, and they were OK. Still some vibration thrtough the steering wheel and brake pedal, but I could live with it.
However, over the next few thousand miles, the problem got worse. Eventually it felt like a badly balanced wheel whenever I touched the brakes.
I mentioned the problem to the chap who owns a local tyre place while they were doing 4 wheel alignment on my other car, and he said it was a big problem with BMWs. He recommended grinding the disks on the car.
The did this for me, and the brakes have been perfect for a couple of months now.
