Trying to sort my handbrake out on my 80,when pulling the handbrake on only the short cable moves at the rear,(passenger side right hand drive)does anyone know if the small bracket attached to the rear diff where the cable splits into two is supposed to move sideways to allow both sides to pull on the brake shoes, or does it have to be tightened up stopping any movement,mine was solid but i have slackened the bolt off and it moves now,dont know whether its siezed or it should be tight,
