HRL, I respect your opinion; but I beg to differ.
What you are saying is true of disc brake systems, but not full drum set-ups...........ever go to the car wash and afterward the car pulled to one side until the shoes dried?
I guess that's "hydraulics"........
I have owned and driven several all-drum brake cars, foreign and domestic and a truck with the Huck brakes on the front.
All will pull if not adjusted properly.......I guarantee it. No physics, no fluid dynamics to it............if a shoe is too close, it will grab sooner and with more force............
This is not to say that hydraulic systems aren't prone to contamination, soft rubber parts, leaks and frozen pistons.
I will stay with my opinion also.
Thanks for reading
