Warped discs

Post by siwel_nerrad » Tue Mar 20, 2018 9:29 pm

Anyone had any problems with warped discs? I've had my M2 since Nov 2016 and had the front discs replaced under warranty because they were warped about 5 months ago. It seems they are warped again for some reason as are my rears. It's booked in for a proper inspection in a few weeks. I don't track the car or drive it hard very often. It's my daily so just mostly drives through town to work and back. Never had the this problem with my M135 and I drive it the same.

Most likely just pad deposits on the discs, BMW service departments will be too lazy or lacking in any proper skills/experience advise on probable causes or to diagnose any actual fault properly and just replace the discs again.
Google 'pad deposits' for possible causes and cures.

This is what I was going to say as I've recently found out it is actually apparently VERY hard to warp the discs - it is often just pad deposits on them given them a warped feeling when braking under load

Take it onto a quite section of road and do a few hard stops in succession (from high speed down to about 30mph) and then drive a distance without using the brakes to let them cool down and see if that helps......

Not only is it very hard to warp disks, you'd struggle to feel it if they were.

If you've been hammering your in Comfort or Sport, chances are the rear brakes have been working hard. You stop at traffic lights with your foot on the brake and you get the above pad deposits and/or a part of the disk that is a different temperature.
