The following are outstanding complaints on the 25/30 h.p. chassis:- Bonnet Rattles. These troubles are the result of the final fitting being left to the Coachbuilders, and we cannot expect to overcome them until our design incorporates the scuttle. Brakes. Inefficient and squeaks, Servo inefficiency, Actuating mechanism stiff. The inefficient brakes is a direct result of town traffic. The continual light use of the brakes produces a polished surface both on the brake shoes and servo lining. We have in hand the BZ. lining for the brake shoes, and we are arranging to fit half a dozen sets to known cars at Cricklewood to gain experience with these liners under town conditions. We have also some special servo linings (Halo 2.L.) which we are trying out for town work. Our experience with this servo disc is the efficiency increases with use. The BZ. linings are better for non squeaking qualities. The seizing or stiffening up of the brake mechanism is chiefly due to a fault in the chassis lubrication. The shafts etc. are well lubricated when the chassis leaves the Works. Continued..... | ||
