While my BJ8 was still on stands after installing the engine and =
transmission, I took the rear brakes apart and installed new cylinders =
and shoes, springs etc. It was a great deal of pushing and shoving to =
get the first one apart so I could clean and oil those items which would =
be moving. Still, I had to take it apart and put it back together 3 =
times before the system looked and worked good. The left rear brake was =
easier and took only 2 assemblies to get it right. Then came the =
installation of the emergency brake. Again 2-3 times before it was =
adjusted and operating. =20
=20
Fast forward to last week when turning on to the Tamiami Trail and =
accelerating up to the 45 mph speed limit in very little traffic I =
approached a cross access of the 4 lane divided highway and carefully =
watched 2 cars waiting to cross in front of me when the big old Lincoln =
Town Car pulled out in front of me. It was a good test of the brakes. =
All 4 activated at the same time, helped by my new Michelin tires we =
stopped a full car length away from the passenger side doors. I could =
see his Mrs. going into shock because the driver had come to a complete =
stop broadside in front of us. =20
=20
Before all this work on the brakes, my BJ8 rear wheels for years would =
activate independently as a result the car would slide sideways. =20
=20
Keep working on the brakes as the life you save might be your own.

Does this help? Note the difference between item 2 and 4.

re: "I note that the slave is tight on the back plate. How tight is=20
normal floating ?"
I just spent several hours on my back on a greasy floor working on my=20
BN2's rear drums. I didn't see any text in the shop manual explaining=20
installation; most I found was a pic in the Moss catalog showing that=20
the curved spring, with the 'hooks,' should be installed above the=20
cylinder (between the cylinder and the handbrake lever). First, I=20
installed the flat plate against the backing plate with the spring plate =
on top of it. Not only would the cylinder not move freely--which enables =
the self-energizing aspect of the brakes--but the rubber dust boot had=20
nothing to hold it in place. I then reversed the installation; i.e. the=20
spring plate was still above the cylinder, but under the flat plate=20
(hooks up). This way the cylinder would slide smoothly and easily, which =
makes sense because there is less contact area, but the rubber boot,=20
which is beveled on the inner part fit naturally under the flat plate=20
and would stay in place when vigorously sliding the cylinder=20
back-and-forth. Contact surfaces were lightly greased.
Short answer: the cylinder should slide smoothly and easily; otherwise=20
the self-energizing feature could be defeated, and the cylinder could be =
stuck in the expanded position, which could explain your non-retracting=20
problem.
