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+.
The average cost for a brake pad replacement, resurface rotors is between $254 to $361. Labor costs are estimated between $182 to $231 while parts are priced between $72 to $130.
$105 for brake pads (front and rear) and $170 for labor. I was quoted $932 for front and rear breaks and rotors. It was steep, but I needed it done and didn't want to shop it around. When I drove out, my breaks were squeeking worse than when I went in.
