| BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} K3458 Φ Hsl/LG2.6.24. 40/50 HP. REAR BRAKE DRUMS. 43458 X9360 As we have pointed out previously, on cars fitted with 4-wheel brakes, we get trouble with the rear brake drums wearing and scoring badly. We recommend that we should increase the brinnel of the rear brake drums. We should like one of the cars going to France to be fitted with these drums with the higher brinnel.
