Changed my pads/sensor on my Mini R56 this evening.
Reused old rotors (discs) since I only changed those around 6 months ago (I didn't change the pads at the time as I bought the wrong ones hence the job being done now just before an MOT).
I did not change the fluid (did that 6 months ago).
I had a nice solid pedal before but now I don't.
I can pump the pedal with the engine off and it goes hard.
When the engine is running the pedal softens up a lot and there's significant travel now before the car starts to slow down.
I find that I then have to pump the pedal to build up pressure, but that pressure disappears quickly and I have to repeat this.
My procedure was sound: I ensured that the brake reservoir cap was off when I pushed the calipers back in. I stopped once the caliper piston was flush with its rubber surround.
All reassembled and pumped the brake before setting off on first trip.
Is this 'bedding in' and do I need to be patient or is something wrong?
Note I have checked the reservoir and the level is not going down.
