| BRAKES. Consistent and efficient. Slight tendency for front axle to "jagger" when applied first thing in the morning. The front are wearing 50% faster than the rear ( 1 notch in 2250 miles) which is to be expected as they are narrower than the rear and yet provide similar braking units. Quickest solution AMR2 linings on the front for the next car and put up with slight brake squeaks (GWH{George W. Hancock - Head Chateauroux} reports squeaks not really bad in previous test with R.R. cast iron drums) GEARBOX. Second speed no good. Comes out far too easily. Synchro-mesh works satisfactorily. STEERING. 25 H.P. type front axle will improve. Rim of spring type wheel very bad for gripping with gloves. EXHAUST SYSTEM. Bad boom 1000 R.P.M. and 2500 R.P.M; A better note would be obtained with fishtail directly out of the end of the silencer. Sliding joints working. No sign of disintegration. PROPELLER SHAFT. No signs of whirling. No leak from the mechanics joints. REAR AXLE. Very noisy from the start. This noise has not increased. Critical speed of crankshaft cannot be reached on top giving 95 M.P.H. at 4500 R.P.M. CARBURETTERS. Roar 40 - 55 M.P.H. A silencer should easily cure this STONE GUARD. For a low car like this having a high maximum speed, a stone guard is almost a necessity if the shutters are not to be damaged and possible the radiator matrix punctured. The front number plate is too low. PETROL PUMPS. The worst feature with these is that when running on main, | ||
