Disc Brakes on the Rear

[the hamiltons]

I cannot compare the system I have and six disc brakes. I've never
driven a coach with all discs. What I can compare is the marginal original
system and Powermaster, 80mm calipers with carbon metalic pads on front and
larger cylinders on the intermediate wheels. Nothing else. I now have good
brakes that work well. Some people have also put 2 1\2" shoes on the rear
and that also works well. At the time I was redoing the rear wheels I
couldn't find asbestos shoes. I might also add that at the same time I
replaced the original rear brake springs, that still had paint on them and
looked good, but what I got was easier adjustment of the rear brakes and my
parking brake back that works! The springs had lost a lot of their tension
over 19 years.

Beg to differ with you Arch, everyone that I have talked to recommends 1
1/8" on front and 1 1/16" on rears. but you are right always put the
smaller brake cylinder on the fronts. Anyone else want to weigh in on this?
Got this from individuals that are using the Powermaster unit also.
