Quick brake question (E46)
Discussion
My E46 330 failed an MOT today on two related things- "front brake application uneven" and "front brake release uneven".
The car drives fine, so this was a surprise. However I was planning on changing the discs and pads all round this summer, so will be doing the front immediately. Quick sanity check though. The MOT failure seems 99% likely (to me) to be down to one of the calipers sticking. Before I go ahead and order a new pair of calipers, new set of discs and pads, is there anything else which I should investigate?

Only (possibly) useful thing I can add is that when I had a calliper sticking, on my E46, it was shown to me as obvious by the mechanic, who fixed it, as it was hot when touched.The car drives fine, so this was a surprise.

Also I couldn't say that the car drove fine as there was some vibration/shaking which ceased after repair.
In a previous E46 I had the caliper properly sticking, the steering wheel would shake like mad and the alloy was red hot. So as you describe (perhaps a more extreme event).
At the moment my current car doesn't do this, but in my logic the caliper only has the stick very briefly as the piston comes out and retreats to cause uneven braking.
