I noticed recently that the back left disk on my 2007 E90 2.0d was getting hotter than the other side. Stripped the caliper off and there was corrosion around the piston so replaced the caliper. The problem was still there after a test. I thought that the brake flexi may be damaged so changed that as well. Still the same. It only gets hot if you use the brakes but when you don't use the brakes, it stays only slightly warmer than the other side. This to me sounds like a sticky caliper or brake again. Any ideas as i am pulling my hair out trying to find what it is!

Have you cleaned the guide pins and the shoulders that the brake pads rest on the calipers mate?

Guides were new on the recon caliper and the pins were cleaned up as well.

check the handbrake isnt sticking on?

The other possibility is theres some air stuck which means the braking is imbalanced? Perhaps try bleeding all four calipers.

Did you fit new pads?

The car got new disks and pads all round about 800 miles ago. They didn't have hand brake shoes when I was getting the parts so these were fitted last week. I set the handbrake up as the manual and it wasn't catching when I was spinning the disk.
