For those who don't know for sure, please refrence manuel. First your doing it right except for starting at the right rear. The reason for bleeding the brakes is possible air in brakes lines because of depressing the piston of the calipers when installing new pads. The god book suggest 12 time of the pedal but I beleive 10 times is good enough. As for ASC you don't have it. It came on 1991 and later 735i/il. ASC is Automatic stability control,uses abs wheel sensor input to the DME to improve vehicle stability by controlling power to the rear wheels. As for air and fluid leaking for the hydraulic oil reservoir for power sterring and on 735il self levelling suspension, I can't help.
