I think I've made a breakthrough on the rear brakes with my Acclaims. On closer inspection of the Haynes manual I think I've reassembled a couple of the springs in the wrong place. Once the rain lets up and I get some time I'll be taking a look. Fortunately this is something which won't cost me any money and will give me a working handbrake at last!
Snowdrop is back in use only because I'm going to a Triumph Dolomite Club meeting so I feel I should turn up in a Dolomite!
