Also with regard to my 2002 Bonneville brake bleeding question, I could not get the rear bleeder bolts loose and did not want to twist them off, thus I bled the rear brakes at the brake hose going into the caliper....Is this acceptable? Thanks
No, you can still have air trapped in the rear caliper/wheel cylinder. Removing the line could introduce air to the caliper or wheel cylinder.
Unfortunately, this means you might end up replacing your rear calipers / wheel cylinders also. It has happened to me a number of times. Be sure to spray it with some good penetrating oil and use a 6 point socket.
