there are measurements for rotors that tell you if yer at
limits and to replace the rotors. never turn 'em. its a waste
of time and money. for those that want to, more power to ya.
after market pads are just fine but many times the prices
are very close to the dealers. i prefer textar but thats just me.
use mb grease but i have found a better grease made by
wurth. no problems since using it.
never allow fluid to back up into the system as this can mess
up the valves in the abs system. bleed brakes with a minimum
of 29 psi in a pressure bleeder.
