To BJ: from Hs{Lord Ernest Hives - Chair}; c. to EY. c. to Wor.{Arthur Wormald - General Works Manager} c. to D/L. CHASSIS 21-EM - MRS. GORING. X9940 F4117 With reference to D/L4/B12.5.25 and the letter attached from Mr. Claremont of the 8th.inst. We can quite conceive that the accident occurred as described in these letters. It has been known that this could happen. It was solely to reduce this effect that the parallel control for the front axle was schemed and designed. On experimental cars we have reproduced similar occurrences which caused the car to go off the road. We chose a suitable road on which to carry out the test. To produce the effect one has to apply the brakes hard, have the steering turned on a fair lock and to be holding the steering wheel lightly. Depending on the freeness of the steering and the efficiency of the front brakes, this fault can be demonstrated on any 40/50 car fitted with 4-wheel brakes. In the Instruction Book, drivers are warned very definitely against applying the brakes when the steering is turned. Hs.{Lord Ernest Hives - Chair} | ||
