Hs{Lord Ernest Hives - Chair}/LG26.11.23. OBJECT OF TEST. Bump tests on 40/50 chassis with 4-wheel brakes. TESTER. C.H.Parkinson. CONDITIONS. Bumping tests. SUMMARY OF TEST. These tests show that radius rods do not reduce our front spring breakages. The steering parts, pendulum lever and rocking shaft have failed much sooner than we get on a standard car. The bump test is now being held up until we get new features fitted as described in R1/M22.11.23. Hs.{Lord Ernest Hives - Chair} | ||
