| -2- (4) Front Brakes. (a) When assembled as delivered, dia. of brake shoes was 1/8" larger than drum. To enable drum to be fitted 1/16" was filed off top ends of brake shoes. (b) Insufficient tension on top brake spring to return shoes to zero after releasing foot brake pressure. (c) Thackary washers placed over distance pieces to allow hydraulic brake cyl. on wheels to "float" cannot function. They are solid when tightened up as distance pieces are too short. (d) The flange-shaped steel pieces making a seal between dust cover and brake cyl. fouled top of cover and were prevented from fitting correctly on dust cover. They were filed to fit. (e) The cast iron cyls. as supplied by makers have to be filed to allow above flanges, which are fitted with rubber rings, to slide over them. (f) The small 'jam jar' covers, supplied to fit over brake cyl. ends do not fit. They have to be faked to enable them to be retained in place. (5) Servo. (a) Hole in X frame was considerably enlarged to clear servo brake rods to master cyl. (b) Support for brake rod, running from servo to counter-shaft was not in correct position. Also it was necessary to lengthen it 2 1/2". (6) Rear Shock Absorbers. (a) Although these are fitted to the plates rivetted to frame members by the makers, the instrument on the right clears rear axle tube by 1/2". The opposite fitting clears by .005". (6) Radiator. The standard rubber slat mounting-central was removed and a scheme fitted involving 4 silent-bloc fittings bolted to sheet steel angles lying horizontally in bottom of rod. Two 3/8" bolts running through silent blocs secured this fitting to 2 sheet steel angles bolted to front frame member. See sketch attached. | ||
