| X.446. Extract from Hsl/LG9.11.23 - HISPANO SUIZA CAR. (X.4214) We have heard that the 4-wheel brakes operated by servo on a 24/60 Sunbeam are very violent in action. With the least pressure on the foot pedal, the brakes are applied so violently that the driver is flung forward and exerts further pressure on the brakes which locks the back wheels.
