Recently purchased a beautiful '95 K75 with approx. 28K miles and ABS (which I understand is standard on this model.) My 4th BMW. Getting used to the brake operation. Rear brake doesn't seem to have much (any?) stopping power when used without the front brake. I am not a heavy rear brake user so I haven't noticed the issue very frequently (also haven't had time to put many miles on it so far). Should I expect to have to use both front and rear brakes simultaneously? Brake fluid was recently changed during a major service at a dealer. Rear brake seem to operate properly during a stationary test on the center stand. Getting ready for a quick 3-day trip around Colorado so any insight will be appreciated. Thanks!
