Hs{Lord Ernest Hives - Chair}/RB{R. Bowen}1/LG17.5.24 OBJECT OF TEST. Measurement of twist of front axle due to braking. TESTER. R.{Sir Henry Royce} Bolton. CONDITIONS. Tests carried out on chassis 35-PK. Figures give total difference of readings for pivot from normal to fully distorted position. All readings are average of six independent tests. SUMMARY OF TEST. Readings taken on N.S. Pivot - from normal setting. Both brakes applied - Max. value .525" AV. value .487" N.S. brake only - Max. value .462" AV. value .400" O.S. brake only - Max. & AV. values. .124" Readings taken on O.S. pivot. Both brakes applied - Max. value .500" AV. value .475" O.S. brake only - Max. & AV. values. .412" N.S. brake only - Max. value .175" Av. value .168" -------------------- Hs{Lord Ernest Hives - Chair}/RB.{R.
