I hope most you take positively my updates on the many comments recently
posted on this thread.
All Parking brakes are still Drum/Shoe Technology. I found no Hydraulics
systems used keep a vehicle in our weight Range used as PB.
Brake Actuation ,howerver is changing..........With a push of a
button....... Linear actuators are pulling cables and small servo motors
are clamping Rotors embedded in calipers.
It appears that most of these systems are on mostly Hi end cars and trucks.
I'm sure they will migrate to lower end products quickly.
No matter how you cut it, Parking brakes are still mechanical.............
but they have evolved into very costly electromechanical systems. Rob
Mueller you were correct about the Volkswagen, Push the button only after
you depress the service brake pedal and you have a motor actuated clamp on
the rear Disc. I wonder what the replacement tab will be when the motors
stop living in that environment?
It would appear that we could retrofit our coaches with some new Technology
that is available to mobility impaired drivers. Take look at the info URLs
listed below.
I and 15 other folks still like the DRUM/DRUM Version of the reaction arm
technology. I Will continue my journey with my manual rear drum PB solution
In an effort to help the Disc brake folks who have nothing.
Let's not forget the Branscombe PB Cable sytem for you folks that
have stayed with the DRUM/DRUM technology. When you look at the
alternatives, his efforts are very simple and cost effective! BTW he has a
few potent KH Ball ramp calipers that are mechanical and at last check they
were still available.
Here are URLs that tell the rest story!

Living on a waterfront is not a matter of life or death. Its more
important than that.
