Obviously rear brakes haven't got any easier as time passed. Taking digital pics is so easy these days but oh so easy to forget until one comes to reassemble the "obvious".
For what its worth, rear brakes are generally dirty and a bit greasy to work on, so in my view it is well worth the time spent dismantling and cleaning. Particularly with regard to adjusters (auto/fixed), bleed nipples and sliding clips ('79) which have a nasty habit of seizing up when you don't want them to. A smear of graphite or copaslip on abutting surfaces is well worth the effort...........and keep an aerosol can of Brake/Clutch Cleaner handy, this is an excellent solvent for cleaning off a greasy thumb print and won't harm the linings.
