Technical 850 Parking brake / Handbrake adjustment?
Other Forum Members can give specific advice, however if your model has the friction pad type adjusters on the brake shoes, then with handbrake cable backed right off, I always adjusted the shoes using a screwdriver to prise them out slightly on their pedestal/pins so that I could just slide the brake drums on, to the point where the drum would just bind a little, then give the drum a tap with a copper mallet to centralise the shoes, the drum would just spin freely then but still in close contact, after that I would readjust the handbrake and work it and the footbrake several times to ensure not binding, followed by a roadtest and recheck for binding or even if any hint one wheel/drum was warmer.
This has stood me in good stead since 1969 on many Fiats and also whilst working as a foreman at a Lada Dealership where Lada models (Fiat 124 under License) used the same system.
Other things I have noticed relating to this system is if cheap brake shoes are used then the brake shoe return springs will overcome the friction pads and so give a poor brake pedal and cause issues adjusting the hand brake
