The cellular determinants of K+ secretion in the principal cell include the intracellular K+ concentration, the luminal K+ concentration, the potential (voltage) difference across the luminal membrane, and the permeability of the luminal membrane for K+.

I have a 2006 325i. Front brake pad $190.61 + Labor $80 Front brake rotors $226.64 + Labor $45 Rear brake pad $130.07 + Labor $80 Read brake rotors $228.46 + Labor $45 Air & cabin filter $87.21 + Labor $39 Brake flush $18.50 + Labor $62.40 So the total comes out to $1319.34.Sorry for all the numbers.hen I bought front and rear brake parts for my e46 323i they were about $500 from the dealer. A friend bought them for his e46 M3 a couple months ago and they were about $1,200. I can't imagine that e90 brake parts would cost anywhere near what the M3 parts cost.
