I have a sticky rear caliper on my E92 335D.
I took the calipers off this evening to see what was going on.
So far I have completed the following:
- Replaced worn pads with new pads.
- Cleaned up discs
- Cleaned and greased sliding pins.
- General clean around the brake area.
With the caliper removed, the disc moved freely so it isn't the handbrake mechanism in the drum holding the wheel back. The sliding pins are all moving freely and the piston slide back in with ease.
When all reassembled the wheel is a little more free but it is still very tight. I noticed if you gave the caliper a slight knock it free'd up and allowed the wheel to spin freely again until the brake was applied.
Any idea's what could be causing this?
Thanks in advance.
